This month’s Notebook topic really doesn’t have anything to do with maintenance. I thought instead I’d give you a small insight into our own operations here, as we near the end of our 25th anniversary year. It’s about our covers – some of which show industrial operations, and some of which are abstract concepts that show a bit more imagination (we’ve used both on this issue).
Choosing an image for our covers is one of the most time-consuming tasks we face around here at the MRO Magazine offices. In fact, the process of thinking about ideas for the next cover usually spills over into home time. Ideas can come from anywhere – reading a novel, glancing through the business section of
the daily newspaper, chatting to people about seemingly irrelevant topics, and of course, from the vast resources of the Internet – forums, chats, Facebook, Twitter, LinkedIn, YouTube and the like.
Our covers are very important because they quickly catch the reader’s eye, and if they look interesting enough – and different from all the other publications that come in the mail – our magazine is more likely to be opened and read.
Of course, coming up with a great cover idea is only one step. Then the idea must be executed. Is the concept one that can be photographed? Will it require a creative illustration? Can we communicate our ideas to a creative supplier who may never in his or her life have been in
a mine, a mill or a manufacturing plant?
Sometimes, we can’t find just the right solution, so our award-winning art director will work to create a compelling image from a variety of existing parts –two or three photographs that when combined relate to the concept we are trying to convey.
Usually, the topic of our cover images is pretty transparent, but sometimes it’s only a hint. Our goal is to create curiosity. After all, printing and sending out a magazine doesn’t make it one that’s read. We feel we need to entice you into picking up each issue, so we want to build curiosity with the graphics and the text and the promise of what’s inside. The cover tells you what kind of content is inside – articles that we expect will be worthwhile for you read.
In this issue, for example, our main cover headline, Predictive Maintenance, aims to draw attention to one of the key themes of the articles in this issue. Our
technical articles and case studies look at various applications of PdM tools, including ultrasound, infrared thermography and vibration monitoring. It’s not so easy to illustrate sound waves or vibration, it turns out. Sure, we could have used a product photograph of sound detection equipment, but we wanted to convey the ‘concept’ of sound waves and the useful data they can impart. We think the background behind the downtime detective on our cover is compelling and interesting.
We’ve created really interesting covers in the past – in fact, we’ve received Gold, Silver and Top Five awards in national competitions over the years in recognition of our creativity. But those judges weren’t regular readers like you. I’d really like to hear your point of view on this issue’s cover. Are our efforts worthwhile? Send me a quick note at broebuck@mromagazine.com.

creased 2.0% in August 2010 to $45.1 billion, Statistics Canada reported in its latest available Monthly Survey of Manufacturing. Gains were widespread across industries; however, the main contributors to the increase were motor vehicle, and petroleum and coal product manufacturers. Higher sales volumes were responsible for most of the gain.
With the increase, manufacturing sales were 17.6% higher than their most recent low, reached in May 2009. Compared to July, constant dollar manufacturing sales increased 2.1% in August.
Higher sales were seen in 15 of 21 industries, representing 81.8% of total sales. Sales increased in Ontario, Quebec, Saskatchewan, Alberta and Nova Scotia.
Inventories levels increased 1.3% in August to $60.0 billion. The rise in inventories over the past three months
from November 2009 to May 2010.
As well, unfilled orders rose 1.5% to $54.7 billion in August. The backlog of orders at manufacturing plants across Canada has been gradually increasing since November 2009.
Glen Ellyn, IL — In 2011, the Bearing Specialists Association (BSA) will celebrate 45 years of successfully bringing together the top-level executives of what is now a $5.6-billion bearing industry in an annual convention designed for networking and knowledge sharing.
The association’s 2011 Annual Convention, with the theme ‘Growing Together: 45 Years Strong’, is planned for April 29-May 3 at the Hyatt Regency Lost Pines, near Austin, TX.
Despite a variety of economic and business challenges — including those of the recent recovering economy — BSA has continued to deliver networking and problem solving within the bearing industry. Both the 2010 Annual Convention and the 2010 Fall Meeting set new attendance standards. BSA anticipates the same response to the 2011 Annual Convention.
Convention planning is well under way for business programs and social events to develop and enhance the industry-specific relationships that are the basis for BSA. As always, the annual event will feature industry updates from the American Bearing Manufacturers Association (ABMA), and the Conference Tables Session, which features pre-scheduled and planned conferences between distributors and manufacturers designed to resolve issues of mutual concern.
The Hyatt Regency Lost Pines, located along the Colorado River, is just 32 km from Austin, offering luxury accommodations, ample outdoor recreation and complimentary children’s activities. Lost Pines is a Four Diamond resort located in a rugged, historic Texas setting. The resort’s Wolfdancer Golf Club (ranked by Golfweek in its list of Top 100 Resort Courses) is just steps from the lobby entrance.

Toronto, ON — Ontario’s Workplace Safety and Insurance Board (WSIB) is moving forward with a Funding Review to ensure its long-term financial stability.
The year-long review will gather expert advice and input from workers, labour and employers on a range of public policy issues relating to the WSIB’s financial future, including a plan on how to eliminate the WSIB’s unfunded liability.
To provide business with certainty and stability during the course of these
consultations, and in order to help slow the growth of the WSIB’s projected unfunded liability (UFL), the average premium rate will increase by 2% for 2011 and 2012.
The UFL is the difference between the total cost of claims in the system and the funds in the system to pay for them. It has increased due to insufficient premium revenue, rising claims and health care costs, and declining investment returns following the recent economic downturn. Currently the WSIB’s projected UFL is more than $12 billion.
The WSIB is also making a number of internal administrative changes that will address the UFL while improving customer service and operational efficiency. This includes a Value for Money Audit of the claims and adjudication process. These actions, along with the modest premium rate increases, will assist in balancing annual revenue with claim costs.
“We are taking important steps in ensuring that the workplace safety and insurance system is financially stable now and for future workers and employers,” said WSIB president and CEO David Marshall. “These steps, along with our continuing commitment to accountability and fiscal responsibility, will steer us toward our goal of achieving full funding, while preserving workers benefits and ultimately lowering employer premiums.”
The average premium rate will rise from $2.30 to $2.35 for every $100 of insurable earnings in 2011 and to $2.40 in 2012. This is well below the average premium rate of $3.00 in the mid 1990’s. The increase is being applied to the average premium rate, meaning more than half of registered employers will see little to no increase, while other employers in high-risk industries with a history of costly injury claims may see increases of more than 2%. Employers with good safety records will continue to be eligible for rebates under the WSIB’s incentive programs.
More details can be found on the WSIB’s website at www.wsib.on.ca.
Chicago, IL — The International Exposition for Power Transmission (known as IFPE) will be held at the Las Vegas Convention Center in Las Vegas, NV, from March 22-26, 2011. IFPE is an international exposition and technical conference devoted to power transmission/motion control and fluid power, as applied through hydraulic, pneumatic, electrical and mechanical technologies. It is held every three years.
IFPE 2011 will be co-located with Conexpo-Con/Agg 2011, the largest international gathering place for the construction industry.
The Power Transmission Distributors Association (PTDA) will host a pavilion to help member companies build their brands and business with customer audiences at IFPE. Space in the PTDA Pavilion frequently sells out well in advance of the show. It helps exhibitors secure prime space that offers more prominence and increased presence than exhibiting on their own.
PTDA members can take advantage of a 15% discount off the non-member rate at IFPE 2011 by exhibiting in the PTDA Pavilion. Space rates include drayage, pipe and drape, directory and basic Virtual Trade Show listings and free marketing materials. More than 2,100 sq ft of space has already been sold in the PTDA Pavilion for 2011.

RESOURCE HELPS WITH DEVELOPING DISTRIBUTOR/ MANUFACTURER AGREEMENTS
Chicago, IL — Identified by members of the Power Transmission Distributors Association (PTDA) as one of the top 10 issues between a distributor and manufacturer, PTDA has created a comprehensive distributor/manufacturer agreement template focused on the elements that need to be considered when entering a formal relationship.
‘Guidelines for Developing a Distributor/Manufacturer Agreement: A Components Checklist’ is a resource for outlining the parameters of a mutually profitable partnership.
Rex Davis, vice-president supply chain, warehouse and aerospace division, IBT Inc., served as chair of the task force charged with developing the guidelines. “PTDA is an association of both distributors and manufacturers,” he said. “We need to work together to deliver solutions to our mutual customers. To do that effectively, we have to be solid in our business relationship and understand what each of our strengths are.
“We analyzed these guidelines from many different perspectives: small, midsized and large companies, distributors and manufacturers, and relationships and processes. The input we received from PTDA manufacturer and distributor members throughout the development process influenced the committee to create a usable resource that is relevant to all of our members.”
The guidelines include practical, customizable language for 38 contract claus-
es grouped in six main sections: introductory clauses, terms and conditions clauses, product and price policy clauses, sales policy clauses, inventory clauses, and concluding clauses.
Developed using sample agreements from many of PTDA’s member companies, each clause includes a description of when the clause may be applicable and provides sample language to use in writing a mutually acceptable contract.
The guidelines include a Microsoft Word document, allowing one to edit, delete or add to each of the sample clauses.
“Communicating on important issues and laying out the expectations in advance with our distributors make it possible for us to focus our joint efforts on helping the customer,” said task force member Dennis Tanrikulu, vice-president of aftermarket sales for NTN Bearing Corp.
“A written agreement that addresses all of those details allows us to spend our time on the activities that drive profitability for both of us. These guidelines will help both parties ensure that each of the components of an agreement are discussed and negotiated before an issue can arise.”
The guidelines are available for purchase at US$349 for non-members at www.ptda.org/agreement. PTDA member companies can download the guidelines at no charge.
Chicago, IL — The inaugural Quarterly Business Index recently released by the Power Transmission Distributors Associ-
This table shows an overview of the results and provides a breakout reading by distributor and manufacturer of the PTDA Quarterly Business Index.
ation (PTDA) shows rapid expansion for the power transmission/motion control (PT/MC) industry in the second quarter of the year. The overall reading of the association’s distributor and manufacturer members revealed an impressive score of 77.0, where a reading above 50 indicates growth.
Conducted jointly by the PTDA and Cleveland Research Company, the new PTDA Quarterly Business Index was modelled after the widely respected Purchasing Managers Index and tracks change in business activity, new orders, employment, supplier deliveries, inventories, prices and backlog in the PT/MC market to arrive at an overall index.
The initial survey showed a robust response, with 122 companies participating — comprising 55 distributors and 67 manufacturing firms. A comparative review of the results reveals that manufacturer respondents are expanding at a more aggressive rate with an index of 81.6, with distributor respon-
dents showing a growth index of 71.1. In addition to improving sales and production, the survey results also anticipated continued strength in the near-term.
Participants were also asked to provide their perspective on the remainder of 2010. The positive momentum in the survey results appears to be reflected in the full-year outlook, which calls for 12% growth in sales on average. This comprises expectations for 8% growth on average for distributor participants and 16% growth for manufacturers.
The Quarterly Business Index is available at no charge through at www. ptda.org/index. The full report includes US and Canadian breakout data, as well as distributor and manufacturer expectations in business activity, new orders, employment, supplier deliveries, inventories, prices and backlogs.

Problem: How can I determine what’s wrong with a belt drive system without stopping production?
Solution: A stroboscope is a wonderful diagnostic tool for belt drives. With a stroboscope light you can:
• Read the original belt’s number and manufacturer without stopping the machine: Run the strobe at the belt’s speed and the fast-moving label and manufacturer name will appear to stop.
• See if one in a series of belts are slipping: Shut down the equipment, chalk or paint a mark across all belts, start the equipment, and calibrate the strobe to the running speed of the sheave. A slipping belt will slow down and separate from the others, as you’ll see from the mark on it.
• Check multi-belt drives for misalignment: If the belts from the example above present a step-type pattern, the sheaves are misaligned. The belt with the most load slips the least.
• Check if a v-belt is worn out. Shine the strobe at the sheaves. Check for shiny groove bottoms, which mean that the belt or the sheave is worn out and the belt is riding on the bottom instead of on the walls.
The methods above require that you have see-through guards, an inspection lid or inspection hole. For the greatest visibility, the guard cover should be of expanded metal painted matt black and the sheaves and inside of the cover should be painted in two contrasting bright colors. With this configuration the guard cover will become invisible in a strobe light.
As always, make sure you observe all applicable safety regulations and procedures, and work safely.

Eliminating failed traps can save large amounts of money. To test steam traps, the two basic pieces of equipment to own are an infrared thermometer and an airborne ultrasonic instrument.
BY BRUCE GORELICK & ALAN BANDES
Properly functioning steam traps open to release condensate and automatically close when steam is present. Failed traps waste fuel, reduce efficiency, increase production costs and compromise the overall integrity of the steam and condensate systems. That’s why traps should be tested on a regular basis — or the neglect may be quite costly.
Steam energy conservation is important to the economy. Consider that:
• Over 45% of all the fuel burned by US manufacturers is consumed to raise steam. Steam is used to heat raw materials and treat semi-finished products. It is also a power source for equipment, as well as for building heat and electricity generation. But steam is not free. It costs approximately $18 billion annually to feed the boilers generating steam in the United States (all figures in US dollars).
• Many manufacturing facilities can recapture energy through the installation of more efficient steam equipment and processes. A typical industrial facility can realize steam savings of 20% by improving its steam system. If steam system improvement were adopted industrywide, the benefits would be $4 billion in fuel cost reduction and 32 million metric tons of emission reductions. (Source: US Department of Energy, Energy Efficiency and Renewable Energy.)
Why do steam traps fail?
Obviously, anything mechanical will malfunction; steam traps are no exception to the rule. Proper maintenance improves longevity and helps reduce maintenance costs.
There are three general conditions that adversely affect traps:
A. Dirt is by far the leading cause of failure, resulting in either a leaking or plugged trap.
B. Pressure surges (due to sudden steam valve openings, improper piping, or trap misapplications), resulting in waterhammer and subsequent damage to the internal steam trap components.

How do we keep problems to a minimum and keep energy costs in check? One simple way is to look for warning signs. Let’s review the most evident signs that should signal a distress call from your steam system.
1. The once-lazy plume from your condensate stacks is now an out-of-control freight train. The steam coming from your stack like a soldier standing at attention is costing you dearly.
2. Condensate back pressures that have slowly been rising have been causing your electric condensate pump to selfdestruct. High-temperature condensate
cannot be handled by conventional electric pumps. Temperatures over 212ºF cause conventional electric condensate return pumps to cavitate. Motors burn out and mechanical seals begin to leak when steam is present.
3. Pressure-reducing valves (PRVs) or control valves fail to maintain set pressures. Fully or partially plugged traps prevent condensate from being eliminated from the steam space. Undrained condensate at PRV stations will back up into the steam line and will wiredraw the heads and seats of the reducing valves. Wiredrawing is when high-velocity water in the steam system cuts (scores) the surfaces of heads and seats. Even small microscopic cuts will prevent the proper operation of these valves.
4. A production capability has been reduced. Open or closed traps that have failed will have a negative impact on production. Plugged traps will back condensate up into the process and dramatically reduce system efficiency. Blowing and leaking traps are costly to production due the added and unnecessary energy consumption.
5. Pipe wall thickness of the condensate system has become an issue. Fully open or partially opened steam traps that are not repaired in a timely manner will deteriorate the condensate return piping. Some of the early warning signs begin with steam leaks.
6. The cost to maintain heat exchanger bundles, humidifiers, HVAC coils and other equipment has dramatically increased. Failed traps will prevent proper operation of sensitive equipment. When steam traps fail in a closed position, over time the stagnant condensate will turn to carbonic acid (H 2 CO3 ). Carbonic acid will deteriorate all the metal it comes in contact with. Beyond increased energy consumption, failed open traps will also cause control and efficiency issues.
7. Water hammer can develop in neglected or mismanaged steam and condensate systems. Water hammer literally sounds like someone is hitting a pipe with a hammer. In some cases water hammer can occur when a portion of the steam condenses into water within steam piping. Left undrained, condensate will spill into the steam system and begin to accumulate. Eventually a wave of water will be created. This slug of water can be carried at high velocity until it reaches an obstruction like a closed valve, a lower elevation, or a sudden change of direction.
A trap that is blowing steam can also cause water hammer. Blowing traps create back pressure in the condensate system piping. If condensate piping is already undersized, the problem will be compounded by the additional pressures found by the faulty traps.
Undrained condensate can back up into the steam distribution piping. From the
Above: In this application, after an ultrasonic test found the trap to be blowing, the downstream condensate line was shut and the test valve was opened to verify test results. The system pressure was 270 psi. At the cost of $10 per thousand pounds of steam produced, the energy loss for this single blowing trap was a whopping $21,000. Right: A 600-psi-rated steam trap is being ultrasonically tested.

Before you begin
Before you spend your hard-earned money, consider some of the characteristics of ultrasound instrument. Ask the following questions:
• How is the sound quality heard through the headphones? (External speakers will be hard to use in most steam environments.)
• Does it lack in versatility? (Will it in
• Waste energy
• Adversely affect production
• Increase maintenance costs
• Create safety issues
• Perform a regularly scheduled steam trap survey.
• Identify system design issues.
• Perform an insulation audit. Areas where insulation has been removed and never replaced will significantly add to your overall steam production costs.
• Using ultrasound detection equipment, test bypass valves if they exist in your steam system. They may be leaking through when they ought to be shut.
• Turn off seasonally operated equipment, such as unit heaters.
• Periodically test control valves or shutoff valves in the HVAC system with a handheld IR temperature instrument and an ultrasonic leak detector. If they are even partially leaking through, they are adding to overall energy costs.
• Audit the system and unused inventory equipment. Remove defunct systems.
• Whenever possible and practical, use a computerized system to control and monitor processes.
Purchase proper test equipment
Even if outside technical professionals are contracted to test the steam system, from time to time, a problem will occur. Time is money. Having the proper equipment and just one trained employee can avoid costly downtime.
The two basic pieces of equipment to own are an infrared thermometer and an airborne ultrasonic instrument. Such equipment is readily available in all price ranges. A thermometer with simple features is fine; however, an ultrasonic listening device should be selected more carefully and must have a clear signal quality.
This is similar to purchasing an audio system for your home and comparing one set of speakers to another set. When listening to a quality speaker system, the nuances of what was actually recorded opens your ears to new level of listening. The same is true of listening to a steam trap. With a fine instrument you can even hear the snap-crackle-pop of steam pass-

• Is it heavy and/or awkward to handle when up on a ladder?
• Does it have an extended warranty period?
• Is there proper technical support via phone or in the field?
• Can batteries be easily charged and replaced?
• Are trial rentals available?
Purchasing an ultrasound device should take intelligent consideration. The instrument must be capable of providing you a clear and discernable signal quality. Labour hours and equipment costs depend on it.
Why use ultrasound to test traps?
Of all the inspection methods, ultrasound is often the most recommended and reliable. Ultrasound is a shortwave, high-frequency signal that does not travel far from its source. By listening to the ultrasonic components of a working steam trap, a user can isolate the signal and easily identify operational sounds. Ultrasonic testers translate high-frequency emissions generated from the mechanical and fluid flows of traps into the audible range where they are heard through headphones and seen as intensity levels on a meter. Some units have frequency tuning to filter out additional signals and to tune in to the sounds of steam and condensate.
Testing steam traps with ultrasound provides results in real time. It isolates the area being tested by eliminating confusing background noises. A user can quickly adjust to recognizing differences among various steam traps.
The ultrasonic detector may be easy to use, flexible and accurate among sound testing methods. However, the ultrasonic instrument cannot tell if a trap is cold or blocked. Therefore, first use a temperature indicator instrument to be certain that the system is operating. Then use the ultrasound instrument to determine if the trap is partially blocked or if backpressure exists at the trap's outlet. MRO

Remote-monitoring system identifies the correct source of a failure, avoiding the unnecessary replacement of bearings.
This case study is a concrete example of the benefit of a vibration monitoring system with remote access on an isolated machine. A wind turbine is an excellent example of such an isolated machine, with difficult access as well.

Since 2006, this machine has been equipped with a OneProd Wind System, a continuous vibration monitoring system.
The measurements are remotely processed by a local service provider that specializes in the monitoring of rotating machines, with the assistance, when required, of the

system provider, 01dB-Metravib.
On April 21, 2009, after an alarm was issued by the instrumentation on the generator, the operator of the wind farm requested the results of the analyses of the latest vibration measurements from the service provider. It also requested a diagnosis of the problem, along with recommendations for maintenance actions.
In parallel, the operator also consulted the subcontractor in charge of the maintenance of the machines, who recommended replacing the bearings of the generator.
On April 22, the service provider and 01dB-Metravib sent the conclusions of their analyses to the operator, along with their diagnosis hypotheses. The study of the most recent vibration signals collected on the generator, as well as the analysis of their time history, showed a few problems with the equipment, including:
• the existence of a very marked periodic shock at the rotation frequency of the generator (1,500 rpm) on the last measurements collected at high speed on the bearing located opposite the coupling
• progressive occurrence of shocks throughout the month of March 2009, and development of these shocks during the month of April 2009
• a strong and concomitant increase of the Kurtosis parameter collected in March and April 2009

• the existence of a similar but less intense phenomenon when the turbine was operating at slow speed (1,000 rpm)
• a notable increase of the vibration components corresponding to the notch frequencies of the generator, which are electromagnetic vibrations generated by the presence of notches on the rotor, these notches hosting the windings or bars that make up the rotor electric circuit.
The conclusions and diagnosis hypotheses were as follows:
• No fault – scaling, wear or defective lubrication – was identified on the bearings
• Possible – but not likely – air gap change (rotor/stator distance) resulting from radial backlash
• Possible temperature phenomenon, which may result from a ventilation problem on the generator, leading to stator distortion and rotor/stator contact
• Hypothesis of a secondary element generating shocks at the rotation frequency. Accordingly, the following corrective actions were recommended: immediate visual inspection of the generator; verification of the fixing of the generator fan, which is mounted along the rotor axis on the opposite side of the coupling, and driven by an independent motor; and control of the bearing backlash.
On April 23, 2009, based on these elements, the machine was inspected, while the electric parameters were controlled.
The on-site operations by the technicians showed that the fixing devices of the generator fan were broken, hence the air flow was no longer correctly oriented, which generated abnormal heating of the machine at the origin of the observed phenomena.
The fan was set back into place during the operation (which lasted three hours), after which the machine could be restarted. The bearing replacement scheduled for the next day was cancelled.
In this example, the diagnostic capabilities offered by the system proved very useful, allowing for a targeted, quick and relevant maintenance action, thus avoiding a costly and useless operation (changing the bearings).
No degradation of the machine was observed, while operating losses were limited to the maintenance time. Furthermore, the operator benefits from the experience of getting feedback on the machine.

safety regulations and maintain ISO quality standards in an increasingly competitive environment. Capital-equipment intensive facilities are finding it critical to make sure that the maintenance department is well-equipped with the tools required to keep equipment running efficiently in order to meet these challenges. That’s where PdM tools come into play, as they
can be used to perform thermal imaging, vibration monitoring, oil analysis, laser sighting-based rotating machinery shaft alignment, and ultrasonic testing.
In order to assure that the PdM tools are optimally used and integrated with asset management information, new models have evolved whereby the tool assists users at a variety of skill levels in performing the necessary inspection
Infrared inspection is an established predictive maintenance (PdM) method that continues to evolve. Recent advances in infrared camera platforms have created a new class of infrared imaging instrument that helps make PdM easier than ever.
Infrared cameras can now incorporate pen-based computing, which — with application specific software — can create a powerful infrared inspection data logger. This product integration has a direct impact on the return on investment (ROI) for thermography programs, as well as on productivity, training and the integration of thermal inspection data with CMMS systems.
Today’s operations managers are under tremendous pressure to decrease costs, increase asset availability, reconcile employee skill levels, comply with
tasks with precision, consistency and efficiency. One such example is the thermal imaging camera that now includes not just an imaging capability to perform infrared inspection, but also incorporates an operating system that can be an interface to asset databases. The infrared inspection tool can now guide the user with route-based inspections and permit the capture of in-the-field incident details through image smart tags.
Route-based infrared inspection Many PdM professionals are familiar with route-based vibration data collectors. Route-based data collection has proven itself to be a productive and effective approach to conducting repetitive inspections of industrial equipment, including rotating equipment, electrical systems and many other critical production assets. A route-based system for infrared inspection cameras is also ex-

tremely desirable, resulting in the acquisition of more reliable data, systematically gathered, stored, and consistently available throughout the enterprise.
Typically, the camera can be operated in several modes, including off-route inspection, learn, on-route and survey (see Figs. 1 and 2).
1. Off-Route Inspection: This mode is useful when the user does not wish to follow a planned path, nor wants any assistance specifying the location of the points to be measured. (Cameras not equipped for routing always operate in the OffRoute mode).
2. Learn Mode : This mode allows the user to teach the camera an ordered list of inspection points (known as a route). For each of the traversed inspection points, the specific location, location detail, and equipment information are captured. Learned routes are saved in indi-
vidual files by user-defined names to facilitate future recall. Note that routes may also be created on a PC.
3. On-Route: A user selects a learned route from a set of routes stored in the infrared camera. While ‘on route’, the camera user is guided through an ordered set of inspection points. At each inspection point, the user has all the predefined inspection point information. The user can elect to take an image if desired (for example, if an anomaly is found, or simply to record the inspection event).
4. Survey Mode : This mode allows a user to randomly review inspection points on a specific route. This permits the user to benefit from the instant recall of predefined location and equipment field values, simplifying data entry and increasing operator efficiency.
Image smart tags

tion, location detail and equipment field relationships into the routing process described above is that users can configure their camera in advance to guide them through a series of inspection points in which each of these fields can be preset, extensively simplifying user input in the field. Since the relationship between equipment, diagnosis and recommendation fields can also be userconfigured on a PC host, in-field typing is nearly eliminated in favour of the automatic population of input boxes and simple pull-down menus.
Image smart tags provide an opportunity to supply new image attributes, change default entries, or select from pull-down lists. As shown in Fig. 1, the location could be “Computer Room 2A”, the location detail field is “Back-up Supply” and the equipment type “UPS” (Uninterruptible Power Supply).
Once the equipment is identified, the infrared camera can offer expert-systembased diagnosis and recommendation options for that equipment. For example, diagnosis options for a UPS system may include: Faulty Connection, Defective Equipment, Improper Crimp, Overload, Unknown Anomaly, Short Circuit, or Other, to name a few. Once identified, the severity field can be identified in the camera and comments added.
Since all information is stored with the image, downloading after an inspection run will make the information accessible in PC software for archiving and automatic report generation.
As with other predictive maintenance modalities, infrared inspection has matured to be a common tool for the maintenance professional. In order to reap the benefits of infrared inspection, recent advances in infrared camera platforms have created a new class of infrared imaging instrument that incorporates many of the benefits of pen-based computing. With application-specific software, it can create a powerful infrared inspection data logger with many traits similar to mature vibration data collection systems.
Such developments have made possible route-based inspections and the use of smart tags to facilitate infrared inspections, better organize infrared inspection programs, optimize manpower planning, increase consistency of data a nd improve the productivity of personnel.

Consider modifying a shaft only with good engineering support. Even then, remember that the greater the consequence of failure, the more generous the safety factor should be.
BY CHUCK YUNG AND CYNDI NYBERG
Have you ever wondered why various types of electric motors with the same hp/kW ratings have different shaft diameters, or why some pump shafts are so much smaller than the shafts of the motors that drive them? And what about those hollow-shaft motors? Knowing the answers to some of these questions, and some of the basics of how shaft sizes are determined, can be helpful to anyone who works with pumps and motors.
Bigger is better, at least it used to be Owing partly to tradition, the shafts of electric motors are often larger than those
of the equipment they drive. Engineers were very conservative a century ago when electric motors first came into widespread industrial use, so they typically designed in a sizable margin of error.
Today’s engineers haven’t changed much in this respect. For example, standard NEMA frame dimensions, which have been revised only once since 1950, still specify much larger shaft sizes than commonly accepted principles of mechanical engineering would require.
Shaft design basics
Shaft size is dictated by torque, not horsepower. But changes in horsepower and speed (rpm) affect torque, as the following equation shows:
Torque (lb-ft) = hp x 5252/rpm.
Accordingly, an increase in horsepower would require more torque, as would a decrease in rpm. For example, a 100-hp (75-kW) motor designed for 900 rpm would require twice as much torque as a 100-hp motor designed for 1,800 rpm. Each shaft must be sized for the torsional load it is expected to carry.
Two basic approaches are used to determine the required minimum shaft size for motors, both of which are quite conservative. One method calls for making the shaft large enough (and therefore strong enough) to drive the specified load without breaking. Mechanical engineers define this as the ability to transmit the required torque without exceeding the maximum allowable torsional shearing stress of the shaft material. In practice, this usually means that the minimum shaft diameter can withstand at least two times the rated torque of the motor.
Another way to design a shaft is to calculate the minimum diameter needed to prevent torsional deflection (twisting)
for a 200-hp motor is designed to withstand twice the rated torque, the shaft diameter of 2.371 in. is at the absolute minimum for the 400-hp rating.
Resistance to twisting method
The other way to calculate minimum shaft size for a motor is to set a limit on the amount of torsional deflection (twisting) that may occur. Resistance to torsional stress is directly proportional to shaft size: the larger the diameter, the greater the resistance to twisting.
A rule of thumb with this method is that the shaft must be large enough that it will not deflect more than 1 degree in a length of 20 times its diameter. To calculate the minimum shaft size to meet this specification, see Formula 4.
Example 2 : For the 200-hp, 1,800-rpm motor from Example 1, the minimum shaft size to limit torsional deflection would be as shown in Formula 5.
The minimum shaft diameters calculated by the torque transmission and torsional deflection methods are essentially the same for Examples 1 and 2. Still, a good approach is to calculate the size both ways, and then use the larger value as the absolute minimum.

during service. To engineers, this means the allowable twisting moment, or torque, is a function of the allowable torsional shearing stress (in psi or kPa) and the polar section modulus (a function of the cross-sectional area of the shaft).
Machinery’s Handbook provides the following equations for determining minimum shaft sizes using both design approaches: resistance of torsional deflection and transmission of torque. Both sets of equations are based on standard values for steel, with allowable stresses of 4,000 psi (2.86 kg/sq mm) for power-transmitting shafts, and 6,000 psi (4.29 kg/sq mm) for line-shafts with sheaves (the proper name for what most of us incorrectly call pulleys).
Some of the equations also are specific to keyed or non-keyed shafts, which is handy for pump users who need to know how to calculate the size of each kind. (see Formula 1)
Most motor shafts are keyed, which increases the shear stress exerted on the shaft. Considering this, motor shaft designs typically use no more than 75% of the maximum recommended stress for a non-keyed shaft. This is another reason why the shafts of electric motors are often larger than the pump shafts they drive.
Example 1: Consider a 200-hp (150kW), 1,800 rpm motor. For a direct-couple application, the standard frame size is 445TS, with a (keyed) shaft diameter of 2.375 in. (60 mm). Using equation [1] (from Formula 1), the minimum shaft size would be as shown in Formula 2.
To see how much of a safety factor is built into the Formula 2 equations, substitute 400 hp for the 200 hp power rating. (see Formula 3)
Since the calculated shaft diameter
vertical motors. These designs allow the pump shaft to pass through the hollow motor shaft, which simplifies the coupling process for pump shafts that must support the heavy water column associated with a deep well.
The calculations for shaft diameter are not quite as straightforward for a vertical hollow-shaft motor. Two variables — the outside and inside diameters of the hollow-shaft — are not standardized, making it impossible to simplify the calculation with a ratio. For this reason, it is easier to demonstrate if a specific hollowshaft is sufficient for a given power rating.
Example 3: A 200-hp, 1,800 rpm hollowshaft motor has an outside shaft diameter of 3 in. (76 mm) and inside diameter of 2 in. (51 mm). To determine if this shaft size is sufficient to transmit the required torque, solve the following equation for P: 80 × P/N = (D4 - d4)⁄D [5] Where: P = power in horsepower N = rpm
D = outside diameter of hollow shaft (inches) d = inside diameter of hollow shaft (inches). For this example, P must be greater than 200 hp to ensure that the shaft will be large enough to handle the torque of the motor: 80 × P/1800 = (34 − 24)⁄3 P = 1,702 hp.
Hollow-shaft designs
Direct-coupled loads exert a twisting force (torsion) on the shaft, placing the greatest strain near the surface or radius and very little on the inside portion. That makes hollow-shaft designs practical for

Or, in metric units:
Theoretically, this shaft is capable of transmitting 1,700 hp, so it is more than sufficient for the 200-hp requirement.
Example 4: The amount of torque that a hollow shaft can transmit depends on thickness of the wall between its inside and outside diameters. A thinner wall cannot handle as much torque as a thicker one. The 3-in. shaft in Example 3 was capable of transmitting 1,700 hp and had a wall that was 0.5 in. thick: (3 − 2)/2 = 0.5 in. How much horsepower could a 3-in. shaft transmit if the wall were only 0.25 in. thick?
80 × P/N = (D4 − d4)/D
80 × P/1800 = (34 − 2.54)/3 P = 314 hp
The effect of a thinner wall is dramatic. The shaft with the 0.25-in. wall can carry less than 20% of the torque of the shaft with 0.5-in. wall.
Summing up
Engineers tend to design using an ample safety factor, and older equipment in particular was overdesigned by even today’s standards. Of course, that is one reason many of us appreciate older machinery. It was darned reliable!
In any case, keep in mind that adding a keyway to an existing shaft weakens the shaft. Likewise, increasing the bore diameter of a hollow-shaft reduces the torque capacity. Consider modifying a shaft only with good engineering support. Even then, remember that the greater the consequence of failure, the more generous the safety factor should be. After all, who wants to board an elevator that was designed and built with no safety factor?

This article is part of an ongoing series. The introduction appeared in Machinery & Equipment MRO’s February 2005 issue and the series has run in every issue since. Previous instalments are archived online at www.mromagazine.com. In this issue, we pick up where we left off in the September 2010 edition, as maintenance manager Bob Edwards gets ready to take on more responsibility in implementing major changes to the mill’s maintenance operations.
After hearing that one of our key millwrights, Dave, had accepted a job offer at another company as its maintenance manager, I called the guys together in the shop the next day, and told them about what was happening. There was definitely a subdued reaction from the group. It was Stan who broke the silence.
“Well, that just means we’ll have to take more of a role, and when we get the new guy, we’ll need to make sure he follows in Dave’s footsteps. What was it you guys used to say to me? ‘Lead, follow or get out of the way’?”
After that, everyone seemed more positive as they trooped out of the shop. Surprisingly, the day carried on as normal, even without Dave being there.
Later, I finished my calculations and figured that by reducing the number and time of our shutdowns, we could realize a gain of at least 2% from the planned downtime — and if we didn’t have the downtime associated with start-ups, we could reduce maintenance downtime by 1%.
Joe couldn’t argue with these numbers and I was sure corporate wouldn’t complain. That thought reminded me that I would have to present to the corporate group next week, so I thought I’d touch base with our reliability manager, Carol. When I called her, she said that she wasn’t quite ready and asked if she could have more time to get all of the reports together. It wasn’t like Carol not to be ahead of schedule, but I told that would be fine.
“Tomorrow’s good — it’ll give me the weekend to look at it,” I said.
The next day, I went to Carol’s office to get the reports.
“Well, the good news is that we are improving very quickly. Our downtime is down to 4%, which is less than half of what it was before. Our cost per ton has also dropped by 10% due to the fact that we use fewer parts and produce more tons. But the bad news is that we don’t

They seemed impressed that we had been able to reduce our unplanned downtime by 50% and seemed really keen when I discussed how we had managed to reduce inventory a little, with a plan to reduce it by a substantial amount over the next year.
“Exactly how much and how are you going to do that?” asked Monte, the vicepresident of finance.
“How much? That I can’t really tell you yet as we don’t have good data on which to base the numbers, but rest assured that it will be as much as possible without putting the operation of the mill at risk.” As to how, I described the usage reorder report that I had asked Carol to prepare. This seemed to answer their questions satisfactorily.
I saw Joe squirm just a little as I next brought up the subject of planned down-
time. When I brought up my chart that showed that we could easily save 2% downtime on planned shutdowns with a probable bonus of 1% of what was now being classified as unplanned downtime, everyone perked up. And when I mentioned how this was very much in line with what the Wisconsin mill had experienced, I’m sure everyone in the room could hear Joe exhale.
Scott, the vice-president of operations, had said very little all through the meeting and I wondered if he really saw value in what we were doing. But he soon allayed my fear when he commented, “Well, Bob, it looks quite impressive with what you’ve shown so far. We’ll soon be at the world-class mark for unplanned downtime, your inventory turns will be close behind and your planned downtime will far outdo any other mill I’ve heard about — other than Wisconsin.
“Now Joe has mentioned a little about how you try and get the guys involved —
and when I talk with my counterpart in Wisconsin, I’m amazed at exactly what the frontline people do. Do you have a measure for that and how are we doing in that aspect?”
If someone opens the door, walk on through Delegate as soon as possible
“Well, Scott, if there is a measure, I’m afraid I don’t know of it — and when I talked with Alan at the Wisconsin mill, he didn’t really know of one either.”
Involve as much as possible
I went on to tell the group about our discussion with the Wisconsin management team, where they told us that this was their operating mode and it was driven by the bottom line. “Their philosophy is that decisions should be made at the lowest level possible and they’ve done everything to allow that to happen. That’s something we’re working on right now and we believe it will give us bottom-

line results, while getting the guys engaged. But it will take some changes, a move towards empowerment and a great deal of trust.”
Joe just closed his eyes and shook his head as I continued by telling the group that we had just started tracking the reasons for delays in getting work done and that we believed a large proportion of it was waiting for someone with authority to make a decision on it — a decision the trades staff were quite capable of making themselves.
“Once we’ve confirmed that is true, we’ll start delegating authority in a controlled way. We can set up some sort of criteria that will allow the work to be completed sooner. This will also involve the operations group, as they will be involved in the decision-making process, so that will help us to include more people in the changes we’re trying to make.”
“Thanks, Bob,” said Scott. “That was encouraging stuff. Joe, I think we can safely say that this mill is headed in the right direction, and as I’ve mentioned before, we’ll be looking to you and people like Bob to help guide the other mills.”
“You can count on that, Scott, and thanks for the support,” Joe replied.
The next morning, Joe called me to his office, where he appeared a little bit anxious. “Bob, please don’t pull a stunt like that again — you know I didn’t know anything about the move to give the guys more authority.”
“I couldn’t help it. Scott just opened up the door and I had to drive through it. I think we came across very well, given their comments.”
“Yes, but as you mentioned, this will involve operations as well, and I’m not sure Fred’s group is ready for this.”
“I think you are selling Fred short,” I said. Then I told Joe about the change I had seen in Fred and about his comments to Kevin about work orders. “I know his guys are ready for it and I’m sure that all Fred needs is a little bit of support and a lot of reassurance. I’ll get him involved very soon.”
“Okay, but in future, keep me up-tospeed with everything you’re going to mention in a meeting!”
Later that day, I got the supervisors and Carol together and told them about what had happened in the meeting with the corporate group.
“Let’s call a meeting with the guys,” suggested Carol. “I want you to tell them about the codes and ask for suggestions on how we can reduce the delays, but we’ll need to be ready for a lot of them! I’ll talk with Fred so he’ll be aware of what’s going on.”
“Why not ask Fred if he wants his guys to sit in on the meeting?” suggested Kevin. “That way, we can be sure that everyone gets the same message. Carol and Jim, our maintenance supervisor, can take a group each and if you take one, then we’ll be able to cover all four shifts.”
“That’s a great idea, Kevin. I can invite Fred to sit in with me and that should help with his understanding.” MRO

ysis (VA) and today a predictive maintenance program couldn’t function without it. VA in the early days wasn’t available to use right off the shelf and usually had to be invented and produced on the spot, where it was needed. Then in 1954, recognizing the demand for this type of equipment, Jim Chadwick and Jim Helmuth started a company that successfully produced vibration measurement systems.
were applied to the manufacturing of Hughes helicopter engines. Over the years, these field-ready units were used by every maintenance facility that serviced aircraft engines.
VA began in 1974 when the Canadian Armed Forces started using it on its Sea King helicopters.
days of VA in the Canadian Navy, I spoke with Jolson Sanford of Windsor, NS. A retired Navy Master Chief, Sanford helped to develop VA equipment and the early standards for measuring vibration in turbine aircraft engines.

in the beginning, when vibration analysis was a brand new tool.
BY PETER PHILLIPS
The early history of the introduction of vibration analysis technology to maintenance is a fascinating story, told here in recognition of MRO Magazine’s 25th anniversary and also to mark the Royal Canadian Navy’s 100th anniversary.
ter and Greenwood, NS. By 1984, most Canadian Forces bases had engine test cells and vibration analysis equipment. When we went to sea, we’d pick up a VA kit to take with us. We’d need it to do repairs and services to the helicopters
brex, made by Chadwick Helmuth, which was the only one available at the time. Before VA was introduced into the navy, we used a screwdriver held against the bearing housings of the Sea King engine. With the screwdriver grip against our ear, we determined if bearings were good or bad.
“This was the only way at the time to troubleshoot faulty bearings. As you got experienced listening to the sounds you felt and heard, you could determine which bearings were close to failing.
“When VA was first introduced, there were no baseline or benchmark readings to determine the condition of the Sea King engine bearings. In the beginning, we used our screwdrivers in conjunction with VA pickups (sensors) attached to the bearing housings. Back then, we even had to make the stand-offs (brackets) in the machine shop to mount the vibration pickups to the bearing housings.
“Once we had them mounted, we would compare the reading on the graph that the VA gear would print out, with what we heard with our screwdriver. If we found a bad bearing with our screwdriver, we would see if the graph corresponded. The graph would have high peaks if the bearing was failing. Bearings with the highest readings would score a ‘4’ on the graph. Other questionable bearings would score lower, usually a ‘1’ or ‘2’.
“Then we would dismantle the engine and check and measure the bearing. We paid special attention to the ones we found bad with our screwdriver and VA. This is the way we developed the first
“We would replace all the bearings during the rebuild and put the unit back into the test cell again for multiple starts and run-ups, while taking more VA measurements. These measurements and repairs were recorded for each engine on recipe cards. Along with the VA graph, the card would be posted on the walls of the test cell office. One of the test offices we had was 12 x 14 ft. We had hundreds of these cards covering every wall in the room. This was the history of every repair that was done to each engine.”
Sanford added that these early years were interesting. “The first VA test carts we built were mobile. The engine would be bolted on to the cart and wheeled behind an earth berm and tied down with one-inch cables. We stood behind an earth berm in case the engine blew up.
“The Sea King T58 GE engine absolutely screamed when it was turned up. The compressor rotated at 26,000 rpm and created 4,200 hp. We really took our lives into our own hands testing those engines in the open air without any protection. Once, in a lead-lined indoor test cell, an engine blew up and the turbine blades were stuck in the walls around the room. Imagine what would have happened if we had tested it outdoors just with a test cart.
“In the 1980s, we built test cells
“As we refined our use of VA on our Sea King helicopters and Aurora aircraft, our efforts began to be noticed by our military colleagues. In 1985, the American Air Force contacted us to go to Memphis to help them build a test cart for their Sea Stallion helicopter. By then we had developed the benchmark readings and it was easy to determine the condition of the engine bearings. They were quite impressed with our methods.
“As time went on, engine reliability improved and the 200-hour teardown and rebuild intervals were lengthened. This had a lot to do with the historical data we had collected on our recipe cards, and our ability to predict failures and test engines.”
Sanford said that many of their bearing problems occurred due to lubrication issues. Faulty lubrication pumps and plugged lines caused premature failures. Whether it’s in the 1970s or now, the reasons for such failures are the same. Lack of lubrication is still a major cause of bearing failure.
Interestingly, the methods of measurement really have not changed much these days either, as experienced maintenance practitioners still use screwdrivers to listen to bearings. The big difference today is the availability of the new technology that has been incorporated in modern vibration analysis equipment.
New VA equipment comes in handheld units that can be quickly used to measure a bearing’s condition; it simply displays a good or bad reading. More sophisticated units measure and analyze the collected data, and though analytic software provide users with useful graphs and reports of the results.
Today, many companies have pur-
many of those who haven’t done so yet continue to purchase services from vibration analysis specialists.
Although VA is more commonly referred to now as condition monitoring, the latest equipment allows vibration readings to be recorded over time using trend analysis software. Gone are the paper records and recipe cards. Today, everything’s right at your fingertips.
Back in Sanford’s day, VA was only capable of measuring high rpm readings. Today, full spectrum measurements can be taken on critically lowspeed rotating equipment to ultra-highfrequency centrifugal compressors that rotate up to 80,000 Hz.
Variable-speed equipment measurements, which once were difficult if not impossible to record and analyze, now can be taken as modern analyzers automatically adapt their diagnostic tools to variable turning speeds during routine data collection.
Even more advanced instruments use dual channels to correlate machinery vibration with process variables. This is accomplished by inputting the process information as a volt signal into one channel, while monitoring vibration on the other.
Of course, vibration readings can be recorded in a CMMS system and you can let it do the data crunching. It can then inform you that readings are out of spec and maintenance on the equipment needs to be scheduled.
This year, 2010, marks the 100th anniversary of the Royal Canadian Navy. I am pleased to dedicate this article to all those retired and active service people who have developed many tools and measurements that we now use in everyday industrial life. MRO

Torque tester keeps hand tools at peak efficiency
The easy-to-use EZ-TorQ II torque tester from Mountz is a cost-effective calibration tester for verifying and calibrating all small hand torque and non-impacting torque power tools. The instrument packs a builtin transducer and graphics display into a small, portable unit, making it suitable for checking torque tools on the production floor or calibrating in the lab. Calibration of hand torque screwdrivers and wrenches, as well as power tools, avoids overtightening problems such as stripped fasteners and parts, and under-tightening problems such as fasteners that can vi-
mine the positional change over time and the influences of given events. The module uses the five-axis sensor to monitor both the vertical and horizontal parallel and angular displacement of rotating machinery. The Vibration Acceptance Check add-on module works in combination with the company’s Vibtool device to measure vibration levels according to ISO 10816-3. The RMS velocity value is transferred wirelessly and stored back on to the Rotalign Ultra system, where the result is instantly evaluated against the machine classification threshold.

More than 280 power transmission and motion control professionals participated in over 750 individual meetings that took place between manufacturers and distributors during the event’s MD-IDEX session.
Brussels, Belgium – EPTDA (the European Power Transmission Distributors Association), an association for the industrial distribution channel in Europe, has hosted another successful industry summit. The event was held in Malta, and drew over 280 participants from around the world.
Among the delegates were 63 firsttimers, nine non-member companies and 30 international guests from the US, Canada, South Africa, Egypt, Japan and other countries.
EPTDA’s MD-IDEX (Manufacturer Distributor Idea Exchange) sessions facilitated over 750 individual meetings between manufacturers and distributors, the highest ever in its history.
The association also hosted its first ever Next Generation event at the Annual Convention, welcoming more than 40 young business potentials and aiming to attract future talent to invest, engage and get involved in the power transmission/motion control (PT/MC) industry.
Hetronic Malta, Vodafone, and others.
“Our aim is to add value to our members’ business and help them succeed,” said Hans Hanegreefs, executive vicepresident of EPTDA. “Malta boasts many achievements across numerous sectors, including pharmaceuticals, mechanical engineering, electronics, maritime products, yacht services, biomedical equipment, aircraft maintenance and many
“We are extremely proud of the success of our association and the Annual Convention in Malta,” said EPTDA’s newly elected president, David Harrow, managing director of Godiva Bearings in the United Kingdom. “The positive energy amongst the members, a strong belief in the benefits that we offer to them, and growing interest from other industry leaders to join us, signals that we are moving ahead on the road to recovery, and helping PT/MC leaders to grow profitably.”
EPTDA’s 2010 Annual Convention was themed ‘Our Future’, and featured prominent strategic thinkers and entrepreneurs, including Daniel Burrus and renowned economist Alan Beaulieu, who shared the insights on lessons learned in the past, and an outlook for the future.
While Burrus focused on the impact of technological development on the industry, Beaulieu (who is known for a magical 96% accuracy in economic forecasting) showed the audience which markets to watch, markets to avoid, where to invest, which industries to move into, and more. Supplementing this futuristic outlook, retail expert Prof. Dr. Joachim Zentes emphasized the role of innovation as the key to success from both the macro- and micro-economic perspectives.
One of the most successful highlights of this year’s convention were the company visits organized in co-operation with Malta Enterprise. The executive chairman of Malta Enterprise, Alan Camilleri, was a guest of honour at the annual business meeting and welcomed participants to explore the trade and economic strengths of Malta, a small but promising business hub that is already home to several multinational enterprises, such as Lufthansa Technik Malta Ltd., Trelleborg Sealing Solutions, Methode Electronics,
other industries that are directly or indirectly related to the PT/MC industry. The company visits are another innovative initiative by EPTDA to share information and knowledge that can be vital to our members’ business growth,” he added.
EPTDA has announced a strategic partnership with CHI Hotels & Resorts to offer privileged rates for business and leisure hotel stays for all EPTDA members. Corinthia Hotels’ CEO, Tony Potter, announced the partnership and discussed the strengths of Corinthia Hotels as a special guest of honour at a glamorous Gala Dinner hosted at the Palazzo Parisio in Malta.
As a yearly tradition and to show a strong commitment to responsible business, EPTDA’s members joined hands to donate EUR 7,400 to the Maltese charity Puttinu Cares Children’s Cancer Support Group.
EPTDA is the largest organization of distributors and manufacturers of power transmission and motion control products in Europe. It represents nearly 200 companies of the industry. Founded in 1998, EPTDA’s mission is to advance distribution and strengthen members to be successful, profitable and competitive in a changing market environment. It is dedicated to providing its members with information, education and business tools required to profitably meet the needs of the industrial marketplace. This year alone, EPTDA attracted 11 new members to its association, and following the Malta convention, several non-members expressed their willingness to join the association.

At NTN, we are dedicated to help you get the most out of your rotating machinery.
Our people contribute to this vision every day. Invite us to roll up our sleeves with you.
Many rolling bearings and other rotationally symmetrical parts made from steel have tight fits onthe shaft. Larger bearings and parts - in particular - can be mounted more easily if they are heated first.
Induction heating is superior to the conventional methods, and particularly suitable for batch mounting. Heating is carried out on complete bearings, rings for cylindrical roller or needle roller bearings and rotationally symmetrical steel parts such as labyrinth rings, roll couplings, etc.
Advantages
•Quick, safe and energy-efficient operation
•Environmentally friendly - no disposal required
•Uniform, controlled heating
•Automatic demagnetization
For the mounting of bearings and parts with a mass up to 300 kg, Schaeffler supplies five FAG brand table-top heating devices -
PowerTherm HEATER10 to 300 -suitable for mobile and/or stationary use. For parts with a mass as great as 3,000 kg, Schaeffler offers and recommends heavy duty standalone devices.
The constant evolution of capacity and efficiency in the field of power transmission increases the standardto be achieved in technical product design. And in the selection of technology partners. Drawing from years of close collaboration with designers and manufacturers, Schaeffler Group implements the latest technology into compact and powerful INA and FAG bearing design solutions. From industrial gears and transmissions to wind turbines and modern rail applications, Schaeffler is driven by innovation and operational reliability to achieveextreme standards of performance.
BEARING.MATE is an accessory used for the safe quick and easy handling of medium-sized and large rolling bearings. It can also be used where bearings are heated prior to mounting. The tool is comprised of two handles and two steel strips. Turning the handles clamps the steel strips firmly on the outer ring of the rolling bearing. The compact packaging also includes two brackets to be used when handling spherical roller bearings and selfaligning ball bearings. The clamps secure the bearing in order to prevent tilting of the inner rings.
The tool and bearing can either be carried bytwo people or by crane using slings (ordered separately). If two carrying slings are used, the rolling bearing can be rotated to any position when transported bycrane. During heating on an induction heating device, the BEARING.MATE remains mounted on the bearing. The steel strips expand uniformly with the bearing, maintaining optimum tension.
BEARING.MATE is recommended for use in conjunction with bearings weighing as much as 500 kg, and can tolerate heating temperatures as high as 160°C. It is available in three different sizes that can be matched to bearing outside diameters ranging from 250 to 850 mm.
