Getting recognition

J

ust after we went to press last issue, we got more good news here at our magazine offices. Machinery & Equipment MRO received another honour, an Award of Excellence in APEX 2009, the 21st Annual Awards for Publication Excellence competition. We’re pleased as punch because this marks the fourth year in a row we’ve received an APEX Award.

Sponsored by Communications Concepts, the international APEX Awards are based on excellence in graphic design, editorial content and the success of the entry in achieving overall communications effectiveness and excellence.

The submission by Ellie Robinson, our long-serving art director, and my-

self, for Machinery & Equipment MRO’s December 2008 issue, was selected from among a total of almost 4,000 entries.

The Award of Excellence is for the competition’s Magapapers & Newspapers category; Apex Awards are given in 11 different categories.

This year’s award will join the others on our wall, along with our multiple Gold, Silver, Top 5 and Top 10 awards from the Canadian Business Press. You may have read in our previous issue about our Top Five award for our technical article, Troubleshooting Couplings, by contributor Lloyd (Tex) Leugner, in the 2009 Canadian Business Press editorial competition.

As you well know, it’s great to receive

recognition for your work. But I think it’s unfortunate that there isn’t more such acknowledgement available for the bulk of our readers, all those maintenance professionals who must endure the pressure of keeping all sorts of complicated machinery and equipment churning along, doing its job.

We know from experience than many of you are true inventors, coming up with unusual workarounds when trouble strikes, doing whatever it takes to get the mill back up, the production line running again, or improving a process so it’s more efficient or effective.

Most people think of the work we do around our offices — putting together magazines and websites — as pretty creative, but it’s unfortunately that few recognize the amazing creativity that shows up on the shop floors in industries across the country every day.

Without your creative thoughts and analyses of various technical prob-

lems, there’d be a lot more lingering troubles on those shop floors. And a lot more downtime.

I wish there was an easy way to make those executives realize the wonderful benefits of the work you all do; that it’s not just about following the engineering standards and formulas that rule mechanical, fluid and electrical systems.

There’s much more to maintaining uptime than that. But without recognition from the top, we expect your job probably can be fairly frustrating at times.

It’s not much consolation, but be aware that all of us here at Machinery & Equipment MRO understand your plight and your challenges.

So if you suddenly start getting some unexpected kudos from up the ladder, let us know. We’ll be happy to share the news that the message is getting through to those who need to know.

Manitoba dealing with men’s depression in the workplace Winnipeg, MN — A silent crisis. That’s how the Canadian Health Association describes men’s mental health — a shadowy crisis that is slowly coming to light, according to the June 2009 issue of the Canadian Health and Safety Report produced by the Canadian Centre for Occupational Health and Safety.

The CHA reports that nearly three million Canadians will experience depression, however in men it is less likely to be diagnosed.

Studies show that men often don’t make the connection between their mental health and physical symptoms, such as headaches, digestive problems and chronic pain. They also may face specific social barriers — e.g. that emotions are a sign of inadequacy — that may prevent them from recognizing and seeking help for their mental health concerns.

In Canada men die by suicide about four times as often as women, but only receive a diagnosis of depression about half as often.

Men often don’t make the connection between their mental health and physical symptoms.

Often men do not recognize their mental health concerns until they have a great personal and economic cost. Men are more likely to seek help if they have a connection with supportive peers and access to health information. So, while workplaces bear significant costs of men’s mental health issues (e.g. increased absenteeism, staff turnover, lower productivity), they are in a unique position to promote employees’ mental health.

Klinic’s Man to Man Project in Winnipeg, MN, is one initiative in place to help reach men through their employers.

The project works to address the issue of unrecognized and undiagnosed depression in men, and how it affects communities and workplaces.

The project provides free services to Winnipeg men and their workplaces by giving a presentation highlighting the signs and costs of mental distress, and strategies to attain mental wellness.

Organizations are pointed to information and resources they can use to promote the overall wellness of their employees.

The project provides promotional materials for display in the workplace that invite men to access free, ongoing confidential support for their mental health concerns, at no additional expense to the organization.

By shedding light on men’s mental health, men who are suffering from illness can emerge from the shroud of

silence and be treated.

To learn more about the Man to Man Project, visit klinic.mb.ca/mantoman/index.html. For information about depression from the Canadian Mental Health Association, visit cmha.ca.

vehicle manufacturing and the primary metals industry.

Manufacturers reported a 0.1% decline in inventories compared to May, with levels falling to $62.7 billion.

This was the fifth consecutive monthly decline.

Fabricated metal products manufacturers (-3.1%) and the primary metals industry (-2.0%) posted two of the larger declines in value terms. However, a 14.0% advance in the value of inventories in the petroleum and coal products industry, stemming from both price and volume increases, largely offset the declines in other industries.

The slight decrease in inventories and the increase in overall manufacturing sales caused the inventory-to-sales ratio to drop to 1.58 from 1.61. The inventoryto-sales ratio remains well above values seen in 2007 and 2008.

The backlog of unfilled orders rose 2.0% in June to $60.0 billion, partially offsetting the 7.0% decline in May. In June, the aerospace products and parts industry reported a 3.0% increase in the value of unfilled orders. Excluding aerospace products and parts, unfilled orders increased 0.9%. New orders increased 18.4% in June to $40.8 billion.

MANUFACTURING TECHNOLOGY SHOW TO REINFORCE IMPORTANCE OF TECHNOLOGICAL INNOVATIONS IN TOUGH ECONOMY

BSA EXAMINES USE OF BEARINGS IN POULTRY PROCESSING Glen Ellyn, IL — The Educational Services Committee of the Bearing Specialists Association (BSA) has released the first in a new series of industry-specific educational publications, referred to as Industry Briefs, which are intended to enhance the association’s existing Bearing Briefs by identifying bearing selection specifics used by individual industries.

The BSA Industry Brief: Poultry Process, details the use of bearings in poultry processing and is available for downloading as both a PowerPoint presentation and a PDF from the BSA members-only website, and as a PDF from the public website, bsahome.org, under Tools You Can Use. Specifically, the Industry Brief maps the poultry process and identifies particular requirements for bearings. For example, in the receiving process, the Brief points out: “This application is subjected to shock loads that require rug-

Toronto, ON — Manufacturing still matters. That’s the message from organizers of the Canadian Manufacturing Technology Show 2009 (CMTS), where more than 500 manufacturers and distributors are expected to convene in Toronto, October 19-22, 2009.

The event will unveil the latest trends in manufacturing innovations and demonstrate how new technological developments can help Canadian manufacturers reinvent themselves on the heels of a recession.

“Manufacturing is essential to restoring a stagnant economy,” said Mark Tomlinson, executive director and general manager of the Society of Manufacturing Engineers (SME), which is organizing the four-day event. “Not only is this sector providing goodpaying jobs, but it’s also helping to develop the innovations that will keep Canada globally competitive.”

“That’s not to say the industry is without its challenges,” adds Tomlinson. With manufacturing sales hitting record lows across almost all sectors and in all provinces, show organizers are sending out a strong message that Canadian manufacturers need to rethink business strategies and embrace diversification in order to survive.

“Businesses have to adapt, whether that means collaborating with other companies to create larger corporations capable of tackling tough markets, or transitioning traditional manufacturing processes to take advantage of emerging trends in the energy, aerospace and medical industries,” he said, emphasizing that CMTS 2009 conference sessions will provide participants with valuable insight into these opportunities.

CMTS exhibits will include the latest machine tools, automation technologies, metal forming, measurement technologies, tooling solutions, production methods and management strategies.

Highlights of the show will include a keynote address by Linda Hasenfratz,

ged cast iron construction pillow block and four-bolt flanged bearings. Corrosion-resistant bearings are usually not required at this stage of the process.”

Subsequent processes considered in this brief — slaughter, scalding and chilling — are given comparable consideration.

The Educational Services Committee hopes to address bearing selection specifics in various additional industries in subsequent Industry Briefs. The BSA Industry Brief: Poultry Process was approved at the association’s 2009 Annual Convention.

BSA is an international service and educational organization of distributors representing a total of almost 100 companies distributing factory-warranted ball-, roller-, and anti-friction bearings and invited manufacturers of bearings and related products.

Mr.0 The Practical Problem Solver

Tips for selecting roller and conveyor chain

Problem: How can we get longer life from roller and conveyor chain?

Solution: The overall requirements of the application are important when selecting the correct type of roller or conveyor chain. Important factors to consider are resistance to the environment, wear life/ strength, and total cost.

The chain selected should be capable of resisting the majority of the chemical and/or temperature requirements it will encounter. If the environment is ambient in temperature, stainless, nickel-plated or Silver Shield CR chains (a Drives Inc. brand) may be considered. (Silver Shield CR series chains consist of standard carbon steel components coated with a zinc-aluminum compound.)

If the environment is elevated or subzero, stainless steel chains will most often provide the best overall operation. In applications where extended wear is a requirement, carbon-steel-based nickel-plated or Silver Shield CR chains are the best choice.

Chain strength is normally defined by its allowable working load.

This value is one at which the chain can be expected to operate at (or below) for an indefinite period of time.

While allowable working load is a function of ultimate tensile strength, it is not measured using the same criteria. Chains can have very different allowable working loads, but have very similar ultimate tensile strengths. A chain manufacturer’s application engineering staff can provide more information if chain strength is a critical factor in a particular application.

Collecting data, identifying weaknesses and making continuous improvements keep the Trudeau airport’s baggage handling system flying.

Photos by Carroll McCormick

H

idden in the bowls of the Pierre Elliott Trudeau International Airport in Montreal is a labyrinthine system of conveyors, chutes, pushers, sorters and tilt trays, powered by hundreds of motors and bossed around by software that in turn makes split-second responses to endlessly-changing real-time data on sometimes thousands of pieces of baggage an hour.

Riding shotgun on this system is Axima Services, a Montreal-based technical management company. It took over the maintenance and servicing of the airport’s baggage handling system (BHS) in September 2005. The Trudeau airport (formerly Dorval International Airport) used to maintain the system in-house, but its growth, increased passenger throughput and an increasingly-complex BHS forced a review of maintenance practices. Airport operator Aéroports de Montréal (ADM) decided to get out of the BHS maintenance business and Axima won the maintenance contract.

“When you calculate everything, the maintenance budget has not gone up.

Axima gets the latest technology and it is their responsibility to keep the staff training up to date. It does maintenance at many airports around the world.

Going with an outsource service, we were gaining expertise,” explains Pierre-Paul Pharand, director, operations, ADM. For example, the most recent belt conveyor ADM commissioned was in December 2005 under the guidance of the same Axima employee who was responsible for the building and start-up of the new bag room at the Athens International Airport in time for the 2004 Summer Olympics.

The Trudeau airport has three baggage handling systems. Two traditional belt-conveyor systems serve domestic and international traffic, and are considered as one in this article. The third system, commissioned in the summer of 2009 to serve trans-border (US-bound) traffic, is an entirely different creature and is not covered here.

The BHS, located under the main terminal, is fed via 135 ticket counters and seven bag drops. Dual, redundant conveyors between the ticket counters and the security room, where bags are

scanned for explosives, provide backup in case of some BHS system failures. After passing through the security room, bags travel to a racetrack-shaped tilt tray system, which deliver bags to piers — airport-speak for the locations where handlers collect baggage on to carts and drive them to waiting aircraft.

That is the short version of the trip, but the delight and the devil are in the details: There are 1,600 pieces of equipment (70 different types) listed in the airport’s Maximo preventive maintenance

software program. There are six kilometres of belt conveyors, and 980 motors sourced from SEW Canada that range from 3/4 hp to 3 hp, with the exception of one 5-hp motor.

Twelve beefy vertical sorters shunt baggage up or down to different parts of the BHS. There are also pushers, ram-like devices that punt bags from one conveyor to another running at a right angle to the first.

The tilt tray system is a 230metre long conveyor, but with a difference: rather than being made of rubber belts, it consists of 212 wooden trays that look suspiciously like the business ends of those seats found in elementary schools. The conveyor goes ceaselessly round and round, the trays tipping baggage into chutes at the correct piers.

Suspended from the ceiling, the tilt tray system is the highest-maintenance part of the BHS, requiring 160 hours per month of preventive maintenance (PM).

In all, the 15 maintenance staff, which includes electricians, mechanics, PLC programmers and IT technicians,

handles about 100 work orders a month for the BHS. The BHS is described as an electromechanical system with a high degree of automation, according to Pierre Loyer, director, Airport Group, Axima. “The equipment is simple and it is easy to maintain, but the system [software] on top of it is where the complexity lies: the automation and IT.” Axima constantly strives to improve the performance of the mechanical system, which by one definition, is the rate at which it processes baggage. The design capacity of the BHS is 5,800 bags per hour. “We run a very intensive continuous improvement program so we can reduce our intervention with the system,” Loyer says. “We use Six Sigma on a daily basis.” (Six Sigma is a business management strategy aimed at improving processes and eliminating defects.)

“It is important to implement statistical measures for the system. At one merge, for example, we were having a lot of jams. The fact that we could measure continued on page 16

how many [there were] gave us information that led us to realize that we could change the configuration of the merge.”

Every glitch, such as a jammed bag, automatically generates an event report, even though it may not affect the system. For example, while MRO Magazine was on site, a bag was caught up by its baggage strap, which had snagged on the corner of a conveyor behind a check-in counter.

Loyer quickly unhooked it, but commented that the snag had nonetheless been logged.

This snag would not have happened had the check-in agent put the bag and its dangling strap in a baggage tub, according to Loyer. In fact, he notes, humans in the system cause far more problems than any mechanical issues.

“We can analyze the jams and go back to the airlines and train [their staff]. We ask airlines to let their personnel take an hour to tour the system and visually see the trouble that they can cause … a baggage strap can rip off a piece of belt.”

Axima keeps $600,000 worth of spare parts on hand. To ensure that the right parts are available, Axima has identified higher-risk parts of the system. “Our target is to always ID critical equipment and the critical parts. We analyze the risks, and the time to deliver parts,” Loyer explains. For example, there is a transformer that reduces a 600-volt feed to 480 volts for the tilt tray. Despite costing $15,000, Axima keeps a spare on hand: were it to fail, half of the BHS would go down. The transformer takes just 20 minutes to replace, but 14 weeks to order.

In a six-kilometre system, conveyor belt selection is a science. “Belt selection is a big, big thing. They are chosen for the right friction situations, or whether the belts decline or incline. Belts can last for years, but if you use the wrong belt in an area, you will get a lot of wear,” Loyer says.

Cleanliness is another challenge, especially in the winter, when the urea used to de-ice the aprons creates more dust than usual. The BHS has nine locations where bag tags are read with bar code readers.

Each reader consists of 12 heads arranged in a circle around a gap between two belts. This 360-degree coverage allows tags to be read no matter what their orientation, but as any shopper knows, bar code readers sometimes are unable to read the data. Loyer attributes the readers’ 96% read rate to regular PM on the heads, with extra attention to cleaning them in the winter. Regular analysis of the quality the output of the bar code printers helps as well.

Axima answers to ADM for the performance of the BHS, but meetings with ADM and the airport’s

tenant airlines are not just to discuss Axima’s report cards.

“A committee of airline, ADM and Axima representatives meet once a month to discuss performance, operational issues and expansion possibilities. This is a steering and operational committee. We give reports on the service levels, system uptime, intervention time, read rates, etc,” Loyer says.

The committee was struck after the BHS became common-use — that is, when all 39 of the airlines at the facility began using the same BHS, as opposed to each having its own. The exchange of information and good communication ensures that everyone understands their roles in keeping this hidden but critical part of the commercial aviation supply chain functioning smoothly.

Thermoplastic bearings handle plant’s assault Different bearings extend maintenance periods substantially for electric lifts in wet and salty environment at Quebec bacon plant.

T

he roller wheels on the electric forklifts used at the Olymel L.P. bacon plant in Drummondville, QC, were causing some serious maintenance issues.

The roller bearings in the wheels were constantly seizing after only a few weeks in service. The operating and service conditions for these electric lifts are arduous, as the environment is wet and salty.

The seals at the ends of the rolling element bearings would become damaged after exposure to the corrosive mixture (salt in water), and the contamination would cause the bearings to seize onto the shafts. These seals were not sophisticated in design (most are O-rings) and could be easily damaged when the packaged meat product, dirt, tie wraps, plastic wrap or other contaminants came into contact with them.

Replacing the roller bearings became expensive and time-consuming, so Marco Vachon, Olymel’s maintenance supervisor, decided to try some new materials manufactured by Thordon Bearings after he heard about some good results achieved at a nearby corrugated box manufacturer, Mitchel-Lincoln Packaging Ltd. of Montreal.

First, Thordon SXL was tested as the actual wheel part (no roller bearings) and the elastomeric polymer material lasted 16 times longer than the original combination of the wheel with rolling element bearings.

To extend the service life, Olymel then tried Thordon’s new engineered thermoplastic, called ThorPlas. ThorPlas bearings were made and used to replace the roller bearing element in the previous wheel configuration, a feature that was not possible with Thordon SXL, as only ThorPlas was capable of handling the higher pressures of the application.

The conversion to ThorPlas roller bearings in the wheels was done in August 2007 and almost two years later, the bearings are still operating satisfactorily. The electric lifts have performed well in this period with no noticeable wear or other issues to date.

Olymel plans to replace all the rolling element bearings in its roller wheels, as well as other applications, using ThorPlas. An order for 24 ThorPlas bearings was recently placed and another order for 48 is expected in the near future.

Olymel L.P., based in St-Hyacinthe, QC, handles primary processing, further processing, and distribution of pork and poultry meat products, with facilities in Quebec, Ontario and Alberta. Its trade-

marks include Olymel, Lafleur and Flamingo, and its products are sold in Canada and exported to 60 countries around the world.

MRO Thordon Bearings Inc. designs and manufactures environmentally friendly, highperformance oil and grease-free bearings and seals for marine, hydro-turbine, pump and industrial markets. For more information, visit www.thordonbearings.com.

Crashing Guns Linear sleeve bearings keep automotive welding line running, putting an end to linear shafting and ball bearing problems caused by welding slag buildup.

T

he production line at a major automotive manufacturer centres around several machines, all working together with production staff to ensure high production rates and quality. A kink in this chain can halt production and greatly increase costs to a staggering level. In this case, the kink was a big one — crashing welding guns on the manufacturer’s production line — so help was called in.

When the manufacturer contacted PBC Linear, a supplier of linear and rotary motion solutions, the welding guns were running on conventional linear shafting and ball-bearing technology.

Welding slag particulate collected along the shafting, causing the system to fall off track and machine inaccurately.

The slag buildup also caused the bearings to stall, seize up, and catastrophically fail — resulting in unplanned downtime and skyrocketing production costs.

PBC Linear recommended the use of

its Simplicity linear bearings and accurate shafting. Equipped with a FrelonGold liner to allow for a high tolerance against contamination, heat and shock vibration, the self-lubricating bearings were wellsuited for the welding application.

The automotive manufacturer recommended installing the parts in the two welding guns with the history of the highest slag accumulation. Eight months later, the manufacturer reported that the new shafting looked as it did the day it was installed. That’s because the Sim-

plicity bearings harmlessly wipe the slag and other contaminants off the shaft, promoting smooth and long-lasting linear motion.

With 150 other welding machines using failing ball bearings, PBC Linear was asked to install its replacement system on the plant’s remaining welding guns.

Tough and reliable, guide wheels tackle any environment and excel under dirty conditions.

achinery and maintenance professionals in industries such as woodworking, machine tools, paper processing, textiles, food processing and packaging often consider guide wheels based on their functionality in harsh environments. In fact, it is not at all uncommon for a guide wheel system to replace an existing linear motion system prone to frequent maintenance or failure.

This is exactly how DualVee guide wheels from Bishop-Wisecarver originated. The design of the wheels provides the ability to outperform other linear motion technologies in environments where dirt, dust, metal chips, wood chips, textile fibre, food particles or other debris are present.

DualVee was invented and patented in 1967 by Bud Wisecarver while designing fertilizer packaging equipment for Standard Oil. The equipment’s flat rollers constantly became clogged with debris, causing the equipment to shut down. Wisecarver knew there must be a better way, and replaced the flat rollers with a double vee bearing, which handled the debris with ease.

The ability to excel under such dirty conditions is largely due to two primary

design features: sealed bearings and the guide wheel’s inner vee design.

Because a guide wheel’s bearings are self-contained and isolated from the environment, there is no contact between the bearings and the track. Other linear motion technologies such as profile rail or round rail systems feature bearings that are exposed to contaminants that settle on the rail. These bearings become clogged, resulting in performance problems, or in many cases, system failure.

In addition, contaminants, when mixed with lubrication, result in a sticky, greasy substance that increases friction and causes excessive heat generation.

Maintenance and repair requirements can prove frequent and costly as a result.

A guide wheel’s inner vee diameter travels at a slower rate than the outer vee diameter, resulting in a velocity gradient that sweeps aside any debris that has settled on the track. As described by an equipment manufacturer in the wood and paper processing industry, DualVee forces the dust and glue off the ends of the track “like a squeegee.”

Other extreme environments The double row angular contact design has now been incorporated into linear

Washdown Challenge

Choosing lubricants for harsh conditions and frequent washdowns.

H

arsh environments call for specially formulated lubricants, and every application dictates the necessary properties for the ideal lubricant. Dusty environments lend themselves to solid lubricants that will not dry out and will not trap dust and dirt. On the other hand, extreme temperatures and frequent washdowns — as found in food processing facilities and other applications — call for lubricants that can withstand water, maintain their viscosity, control rust and corrosion, and will not be washed away.

Research indicates that synthetic lu-

bricants can provide superior performance to mineral oils in extreme-temperature and wet environments. Mineral oils are produced using a solvent-based refining process. Due to the manufacturing process, they tend to retain a significant number of impurities, such as sulphur or aromatics, that result in decreased thermal and oxidative stability, leading to premature degradation of oil.

In addition, impurities such as sulphur-containing species lend polarity to mineral oils, which can generate an increased rate of emulsification when compared to synthetics.

guides and actuators, as well as hightemperature, low-temperature and washdown versions, to conquer the demands of a wide variety of extreme conditions.

These specialty guide wheels are geometrically identical to the original wheels for interchangeability, and because they incorporate the same design features, they offer long life and reliability where debris is major a factor.

Other considerations Guide wheels have other distinct advantages, providing the versatility to meet requirements in a wide range of applications: • Noise level reductions by as much as 20% compared to other ball circuit technologies • Smooth, low-friction motion • Speeds up to 5.5 m/s • Acceleration up to 5 g’s • Accommodates both axial and radial loading • Inner or outer vee load-bearing surfaces.

Guide wheels are easy to install, and because they are lubricated for life, they are virtually maintenance-free. Replacement, which is required less frequently due to long life, typically takes minutes.

Adjusting a guide-wheel based system is relatively simple, with little to no surface preparation required, resulting in higher productivity, longer maintenance intervals, and reduced downtime. Guide wheels provide a cost-effective and long-term solution in dirty environments.

Synthetic lubricants are produced through chemical engineering and designed to meet certain performance parameters. Compared to mineral oils, synthetic fluids are inherently more chemically inert. Certain synthetics such as polyalphaolefins (PAO) lack polar sites, which means they offer no inherent attraction to water, allowing free water to separate from the oil and go to the lowest point in a system, where it can be easily drained off.

PAO greases used in the food and beverage industry possess the same properties as PAO fluids and can be formulated to be extremely tacky in order to resist water washout and spray off. For example, Molykote G-1502FG Synthetic Chain and Open Gear Grease has proven successful in washdown environments in food and beverage applications. It has demonstrated the ability to reduce the amount of grease used to lubricate washdown-application bearings. The grease stays in the bearing after repeated washdowns, reducing the ability of water to enter the bearing housing.

Polyolesters (POE) are synthetic lubricating fluids that possess excellent thermal and oxidative stability and can tolerate water very well. POE oils are often biodegradable. Due to these facts, POE lubri-

cants, such as Molykote L-4646 Synthetic High Temperature Compressor Oil, are a good choice in rotary screw compressor applications. POE oils have demonstrated greater than 14,000 hours of service life on a single fill. Unlike hydrocarbon-based lubricants, polyolester lubricants will not form varnish and sludge deposits.

Silicone fluids can be used to formulate greases that perform extremely well over a wide range of temperature extremes (-73°C to 288°C). Silicone fluids have an inherent viscosity index of 400500, which means that in comparison to other lubricating fluids, the viscosity of the oil will not alter much over differing operating temperatures.

Operating efficiencies may be increased as a result of lower viscosities of silicone lubricants at extremely low temperatures, since less energy is required to create motion and operate bearings and other mechanical components, leading to cost savings and lower carbon dioxide emissions.

Vibration analyzer ensures bearing reliability in gearbox refurbishing

The success of vibration measuring equipment in bearing refurbishment for the aerospace industry has led to increasing interest from other areas of industry. This report gives details of the development of the technology.

F

ifty years of ongoing development has given rise to a bearing vibration analyzer that can probe deep into rotating bearings while they are under load. Initially used as a production line tester, it’s now proving invaluable during the maintenance and refurbishment of gearboxes and other critical units in demanding applications such as aerospace.

However, the creation of a bearing vibration analyzer wasn’t as easy as some might think.

A good first step towards solving any problem is to get the facts. And that’s exactly what a group of senior engineers at SKF did in the early 1950s.

It was said that, collectively, the group members knew everything there was to know about bearing materials, bearing design, bearing manufacture and bearing applications. But still the SKF engineers had a problem. They were concerned about the causes of failure that bearings from all manufacturers were exhibiting.

Minute exterior examination of bearing components and bearing assemblies could only take them so far. They wanted more facts. They wanted to probe deep inside a bearing while it was rotating, and while it was under loads similar to those it would experience in service.

Intuitively, they knew that vibrations caused by the rotating and flexible parts in a bearing caused noise and could be a source of wear and bearing damage. But they also felt that understanding the vibrations better could tell them even more — perhaps even tell them what caused the vibration in the first place and how to design and manufacture in order to reduce the vibrations and the corresponding wear.

So the company set off on a path to develop an understanding of vibration phenomena in bearings, as well as find a method of measuring vibrations and connecting this back to distinct causes — as specific as rolling element induced vibration or damaged ring induced vibration.

By the mid-1950s, the group had successfully created its first vibration testing equipment for analyzing structureborne noise and vibration in bearings. It went on to develop equipment that would reveal problems hidden within a bearing, such as: dirt particles, cage noise, or form deviations in a component. Their search had revealed the factors that could lead to bearing failure and customer dissatisfaction.

Early milestone Early versions of the equipment were introduced into production line testing but the group continued to probe further, until in 1965, one member of the group, E. Yhland, reached a milestone in the understanding of the quasi-static problem of bearing vibration.

His work became a contribution to establishing national standards such as AFBMA 13-1987 and DIN 5426 (draft).

These standards define and specify the physical quantities to be measured and the test conditions to be applied. The equipment became of extreme importance for high-quality bearing production.

Today, SKF equipment such as the MVH Vibration Tester is used to analyze precisely the structure-borne noise and vibration of deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, and spherical roller bearings. The MVH is also used as the SKF reference equipment for these measurements.

Operation of the MVH 90C/200C Vibration Tester is semi-automatic, so when a bearing is to be tested, the only things to be done by hand are: the loading of the bearing on the test spindle, the pressing of the two-handed start, and the removal of the bearing after the test.

An extremely precise sliding bearing spindle drives the inner ring of the bear-

Expanding vibration testing applications SKF-developed vibration testing equipment used by Rolls-Royce for noise testing of bearings during gearbox servicing has been released for other applications.

Release became necessary when Rolls Royce Deutschland decided to transfer service work on gearboxes for secondary power systems to the subcontractor Vector Aerospace in Almondbank, Scotland. Overhaul of the gearboxes required detailed inspection of more than 3,000 components, some of which require testing with special equipment. The components include various types of rolling bearings used in the gearbox, whick require stringent noise and vibration testing, and measurement of the radial and axial clearances.

Vector Aerospace selected SKF as the best suitable supplier of test equipment for the bearing tests. But before putting the equipment to use, it was necessary to run a release process with Rolls-Royce Deutschland. A detailed test and acceptance program was developed by Rolls-Royce Deutschland using reference and series bearings from different manufacturers to confirm the usability of the noise-test equipment after its installation at the Vector Aerospace site.

Top: Rolls Royce was an early user of vibration analysis for its aircraft services. Below left: SKF’s bearing vibration analyzer comes as a complete system.

ing at a constant set speed, while loading is provided by an adjustable, pneumatic axial loading unit. When the automatic test cycle begins, the axial loading unit applies an axial load to the outer ring and moves the bearing against the testing spindle.

A pickup is applied to the stationary outer ring of the bearing and any bearing noise is measured, analyzed and displayed. After a pre-determined time, the axial loading unit returns to its rest position and the machine is ready for the next test cycle. Resetting for another type of bearing can be done quickly and simply.

The tip of the pickup rests against the outer ring and converts the radial vibration of the bearing into an electrical signal that is proportional to the velocity of the pickup tip. When the signal is amplified and analyzed, the vibration level is measured in three frequency bands. The result identifies one or more

Reducing costs and ensuring reliability The great success of vibration measuring equipment in bearing refurbishment for the aerospace industry has lead to increasing interest from other areas of industry.

There is also increasing awareness of the savings to be made from the re-use of bearings that have been tested and meet quality and reliability standards.

Other examples of the vibration tester’s versatility are its use in manufacturing companies where the equipment can be used to inspect incoming components, and its use in research departments to support R&D activities or act as a test rig for gears, motors or steering units and so on. The equipment is equally useful for grease noise testing.

Although the bearing vibration analyzer has come a long way since the 1950s, its development continues at SKF, where the search is on for even more accurate measurements and analysis. At the present time, research is focusing on three interesting areas: the application of different sensor technologies, the use of a detailed noise map, and the introduction of an expert system.

Owners vs. Suppliers Who’s Responsible for Compliance?

Photo Bernd Klumpp, © iStockphoto.com

To avoid unnecessary liability, many purchasers of machinery and equipment pass the responsibility for PSRs on to their suppliers.

BY SIMON FRIDLYAND

M

any of my clients who are engineers complain that they are experts in their specific fields but might not necessarily be experts in machine or robot safety, or in areas such as flammable liquids.

Yet once your company becomes the owner or lessee of equipment with these concerns, it also becomes responsible for its compliance to the requirements of the Occupational Health and Safety Act (OHSA).

Owners and lessees of equipment or processes related to the storage and dispensing of flammable liquids, machine guarding, racks and racking systems, potentially explosive processes, dust collectors, molten metal and foundries, lifting devices, or occupational exposure to hazardous substances, are increasingly becoming responsible for making sure that the process, machine or device that will be used in their industrial establishments is in compliance with provincial OH&S regulations.

In Ontario, this is achieved through the so-called Pre-Start Health & Safety

Equipment owners or lessees are responsible for ensuring machinary, equipment and processes are in compliance with government regulations.

Review process or PSR, where a professional engineer must review the hazards of the above equipment or process and issue a report that the equipment is in compliance with the applicable standards.

A section of the OHSA dealing with PSRs was substantially changed on October 7, 2000. The amendment allows the parties in the workplace to become more self-reliant in preventing hazards to workers — and they are now a major part of the internal responsibility system in the workplace.

The task of developing guidelines for engineers providing PSRs was assigned to Professional Engineers Ontario (PEO).

Engineers carrying out the PSR must be

familiar with the equipment under review and must understand the principles of hazard analysis and issues related to occupational safety. He or she must have a thorough knowledge of the OHSA and codes and standards applicable to the equipment under review.

The professional engineers who sign and seal the PSR report are professionally and legally responsible for the statements made in the report. Engineers are held professionally accountable through the PEO’s discipline process, which may result in a reprimand, a suspension or revocation of their license to practice or other penalties if the PEO’s committee finds any wrongdoing on the part of the engineer.

Legal accountability may occur through a lawsuit brought by an injured party. OHSA allows for fines and/or imprisonment for contravention of the act.

This liability is not insurable and cannot be transferred to the employer if charges are laid against an engineer. This risk of liability warrants the necessity for personal liability insurance for engineers required to sign and seal PSR documents.

Failure to comply with the requirements of the Industrial Establishments Regulation in Ontario could now result in prosecutions and penalties for officers, directors, owners, lessees and engineers.

A corporation that is convicted of noncompliance could face a maximum fine of $500,000 per count. For individuals, the maximum fine is $25,000 per count, plus a 20% victim surcharge levied on all fines imposed by the courts, and/or imprisonment for up to 12 months.

The federal government has recently introduced amendments to the criminal code in Bill C-45. Under Bill C-45, new criminal offences are created for corporations and individuals who fail to protect workers and the public. Those who undertake, or have the authority to direct how other people work or perform tasks, are required to take reasonable steps to prevent bodily harm to any person arising from the work.

To avoid unnecessary liability, many purchasers pass the responsibility for PSRs on to their suppliers by stating in their purchase orders that suppliers must obtain a PSR from a professional engineer, licensed by Professional Engineers Ontario, before a shipment is accepted.

This policy has proven to be an effective one in ensuring that equipment is compliant before it is shipped. It requires original equipment manufacturers to supply a product that will comply with the regulations in the OHSA to avoid MRO extra costs and delays.

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 June 2009 edition, as maintenance manager Bob Edwards and members of his team return from an information-gathering visit to a big US paper mill. We join Bob on his way home.

I

reflected on what we had just seen as we travelled back from the paper mill in Wisconsin and realized that there was a constant theme of improving that ran throughout the plant, starting with the bottom line. We had made some strides in our own mill, but we still had a long way to go.

I must have looked pensive, as Carol, our reliability manager, commented, “Don’t worry, Bob, I know it’s a lot to think about, but I really believe that we only have to take small steps and we’ll be getting close. Everyone at our mill is poised to make the change. Once we really start, I’m sure the momentum will take over.”

By the time I arrived back at my mill the next morning, I had some ideas that would hopefully get the ball rolling. I called Joe Davis, the plant manager, to see if I could go over our visit to the US mill with him and tell him about my new ideas.

“Sure come on up to my office at 10.30 — I’m looking forward to hearing what you learned.”

Suddenly, Carol appeared at my office door. “Well what do you think — are you ready for the big push?”

“Come in, sit down. Let’s talk. I’ll be meeting with Joe later this morning and I want to run something by you. You saw how Chuck, the Wisconsin mill’s maintenance manager, was front and centre there. He wasn’t just their mill manager; he was the champion for their operating mode. I’m going to ask Joe if he will do the same for us.”

“You’re right about Chuck. It was definitely top-down as far as the strategy was concerned. But it was completely sustained by the guys on the floor.”

‘That’s it. I think we’ve got the guys on board and I know Joe supports us.

We just haven’t pulled them all together.

If we can do that, then Fred and his production group will have no choice but to join in. In fairness to Fred, as our production manager, he seems to be at least interested in changing. I know if Joe were to actively ‘champion the cause’, Fred would be fully on board” “Well, we’ve seen the results at the other mill, so I think it’s worth a try.”

By the time I got to Joe’s office, I had a plan as to how I could get him involved.

“Come in, Bob. Tell me all about the ‘wonder mill’. Was it as good as

everyone has made out? ” “If you mean, are they very profitable, the answer’s yes. If you mean, have they grown their business since start-up, that’s an emphatic yes. Are they the preferred supplier for their customers? Yes again. Do they have very little turnover?

Yes, one more time!”

“Okay, okay. Those are good things about the company. But what about the mill?, Joe asked.”

“That was about the mill, Joe, and pretty much anyone at the mill would have answered the same way I did. They all understand that those things are the most important ones and take great pride in telling you about them.”

“But what about their predictive systems and things like that?”

Everyone is focused on the bottom liine “They’re all fine, but what makes the biggest difference between that mill and any other that I’ve visited is that everyone is focused on the bottom line.”

I went on to tell Joe about our discussion with Chuck, their maintenance manager, and Alan, their mechanical team lead, and about their insistence that the way they operated the mill was the way it was because they felt it would give them the best bottom-line results.

“Don’t get me wrong. The whole set-

up is fantastic, but it was all secondary to the results — and that’s something I wanted to talk to you about.”

Joe seemed a little uncomfortable at first, as I explained that Chuck was the champion at the plant and that he insisted that the end justified the means.

“Everyone at the mill talked the same talk — about the well-being of the company — so it was pretty obvious that this approach was top-down driven and that the guys on the floor sustained the approach,” I commented, stealing Carol’s words.

I talked about the pride and the neatness that was everywhere in the mill.

“I realize that we can’t make too many physical changes to our mill, but if we did things like brighten up the control rooms, use the 5S approach and start to involve everyone in a business perspective, I really believe we can make big improvements to our bottom line.”

“I’m sure you could get some of those things done — a few lights and a coat of paint here and there. You already involve your guys more than anyone, so that’s not a problem.”

The mill needs a champion for change “I guess I need to be more blunt, Joe. It’s not about what I can do; it’s about what you can do. We need a champion at this mill. Someone who can transform what we in maintenance are trying to achieve into ‘the way we operate’, all based on the idea that what’s good for the company will be good for us all. And whatever is good for the individual must be good for the company. So what do you think, Joe? Can you be the champion?”

“I’m not really sure what to say, Bob. I don’t know what it is you want me to do.”

“That’s the problem Joe. I’m not really sure either. I just know that what I saw works.

Then I told him what I had in mind.

“What I was thinking was that you make an announcement that we have an improvement project that involves everyone — something that is bottom-line driven.

“Right now we produce 565 tonnes of paper a day, so why don’t we develop a plan to increase it to, say, 600 tonnes per day? We could identify the issues that prevent us from reaching that level today and then develop a path forward. One of the things that I learned in Wisconsin is that succeeding is about partnerships — from a maintenance perspective, it’s partnering with operations, purchasing, scheduling and so on. Nobody succeeds alone.

“So what do you think?”

“Hmm, this actually falls in line with the corporate goals, so it may be a good idea. We could call it ‘Solution Six Hundred’ or something.”

“The way they approached it in Wisconsin was to explain what it is we’re hoping to achieve. Then they told everyone why they needed to succeed. This was followed with the plan for the road-

was followed with the plan for the roadmap and then it was explained — on an departmental and individual basis — what part they played in it.”

“Okay, I think I’ve got the idea, Bob. We could have departmental goals that would add up to 600 tonnes per day and we can ensure that if any department is struggling, then the rest help out. I’ll pull these ideas together and hold ‘town hall’ meetings this week to announce what we’re going to do.

“Obviously the first step will be to analyze what our problems are right now, and then, to be honest, I’m going to depend very heavily on you and the other department managers, as you will know more about the solutions.”

“Sounds good, Joe, but this can’t be smoke and mirrors. We’ll only get one chance at this and it’ll be a tough go for some people.”

I went on to tell Joe that the ‘fit’ of people in this sort of culture was extremely important. “They lost people early on as they couldn’t accept the way things happened; those that stayed took on greater responsibility.”

I described that there were no shift supervisors, and more importantly, the operators and maintenance took care of problems on the off-shifts.

“I don’t know how Fred will accept that. He likes to be called for everything.”

“That’s true, Bob, but obviously we’ll have to give the tools to the operators before we stop the calls to Fred. We’re going to think long and hard before we make these radical changes and you know what — we’re going to involve all levels in them.”

“Wow, that’s the spirit. Just be careful to let everyone know what their level of decision-making is.”

I brought Joe up to speed with the way things were done in Wisconsin and how they had adapted to 5S. “We need to have someone trained in 5S, maybe one of Fred’s people.”

“I think we have enough work ahead of us, Bob. Let’s get this rolling but don’t forget that we need to track in detail what we are doing. Because of corporate’s response to your efforts, we’re going to have to give them a template to be rolled out.”

‘I’ll make a start on moving our department down the path we identified.

This visit just reinforced that we’re on the right track.”

The meeting had gone better than I could have imagined and I felt confident that we could achieve a lot of the success MRO I had seen in Wisconsin.

Big Wheel Clutches and actuators provide a smooth ride for China’s Great Wheel. The actuators can be subjected to low pressure jets of water from all directions, while the clutches keep the carriages steady in strong winds.

I

n Beijing, China, plans are underway to build the Great Wheel of China, a giant ferris wheel that will hold the record as the world’s highest observation wheel, with views reaching the famous Great Wall of China.

The wheel’s manufacturer, Sigma, is using linear actuators to open the doors and electromagnetic clutches to control the yaw of each of the 48 observation carriages. These components are being provided

by Warner Electric, part of power transmission group Altra Industrial Motion.

When the world’s tallest ferris wheel is completed in late 2009, it will stand 680 ft high (208 m), which is over 130 ft (40 m) taller than the current highest wheel, located in Singapore.

The wheel will have 48 air-conditioned carriages that will each be able to hold 40 passengers, giving it a total of capacity of 1,920 passengers. The wheel will be so high that on clear days passengers will have a view stretching all the way to the Great Wall of China.

The wheel is predicted to make 750,000 rotations over a period of 50 years, so only products that are designed to deliver extended service life were considered, according to the manufacturer.

Linear actuators for each of the 48 carriages will be used as a secondary lock to prevent the door from opening during rotation. The actuator was designed in accordance to customer specifications, which included an adjustable end limit switch, end stroke signalling, specific stud, nut and washer arrangements, a manual release lever and extruded aluminium tube Page bodies1 MSD/MRO 3/31/09 10:56 AM

to avoid corrosion and reduce weight.

Warner Electric designs and manufactures a full line of maintenance-free linear actuators for applications ranging from light to rugged duty. Each actuator has an ingress protection rating of IP65, meaning they can be subjected to low-pressure jets of water from all directions. All products can be mixed and matched to accommodate custom orders quickly and effectively.

Each cabin of the Great Wheel of China has also been equipped with a Warner Electric electromagnetic tooth clutch to provide stability to the carriages. The clutches will prevent the carriages from swaying in the wind, which is necessary to prevent passengers from suffering from motion sickness throughout the 20-minute ride.

The clutches keep each carriage axis

vertical as the wheel rotates. If the carriages were left to hang freely, they could sway too much for comfort in the strong winds that are present at such a height.

A tooth clutch provides higher torque in limited areas, which means that the relatively small clutches are able to stabilize the cabins, according to Pierre Lootvoet of Warner Electric. Each clutch has a flexible coupling that compensates for misalignments and allows for easy mounting. In the event of the transmission locking on the wheel, the clutch will be disengaged to leave the cabin free. A hand release lever also allows for manual disengagement.

How to justify a CMMS system purchase

BY PETER PHILLIPS

Answer these 10 questions and you’ll know for certain if you should invest in computerized maintenance management software.

R

ecently, we have worked with some companies that have been trying to decide if it’s time to purchase a computerized maintenance management software system. I’m sure there are many other companies and facilities out there that are contemplating the same question. How do you know when it’s time the purchase and implement CMMS? For many maintenance departments, the shift from a file cabinet full of equipment folders, purchase orders and preventive maintenance inspection lists, to a CMMS, is a big step.

Determining whether it’s a step in the right direction is often a very difficult decision.

So let’s look at some of the key warning signs that can help you make a strong case to move into electronic record-keeping … or not, as the case may be.

How do you know when you’re ready?

1. First of all, answer this question: how full is that filing cabinet?

Do you have 100 or more individual equipment files that you maintain with written service records? Do you keep a written file of equipment spare parts that you continually maintain and up-

date? Along with that, do you have another file folder for each machine that includes the preventive maintenance (PM) schedule and check sheets?

I’m not saying that you can’t have an impeccable paper file system. What I want to emphasize is the time it takes to maintain a paper system. Updating equipment service records, writing down spare parts and modifying inspection sheets takes time. As the file folders get thicker, it becomes harder to find the information you’re looking for. Even with a well-organized filing system, you have to admit that the bigger the file, the longer it takes to sort through the records to find that one piece of information you need.

By contrast, a CMMS can retain all your equipment records and return specific information in a fraction of the time it takes to look in the paper file. A CMMS can retrieve the data you’re looking for before you can even open the file cabinet drawer.

Updating parts list and preventive maintenance procedures in a CMMS takes

Overall, a CMMS will save most companies time and money.

only seconds — and often, equipment parts lists are automatically updated from the service records you create in the software.

2. Do you have a parts storeroom?

A threshold of about 500 parts usually means that you’re spending a fair amount of time ordering parts and maintaining an inventory of commonly used items.

The shortcomings of a paper system for inventory and purchasing relates to finding the right vendor when you need to order a part.

Shops that use a paper system tell me this is where they spend the majority of their time.

Do you want to know how many parts you have and where they are in the stockroom?

It’s advantageous to know where the parts are on the shelf, as well as the number in stock. With an electronic system, parts are easily located and reordering is very simple.

3. Would you like to consolidate your purchasing?

From a purchase savings perspective, it is nice to know how many units of the same item you’re buying. With this frequency of purchase data, you can talk to your vendors about some bulk purchases and discounts. This is difficult to do with multiple purchase order books.

4. Do you know when equipment is due for servicing?

When it comes to preventive maintenance, and when you’re trying to manually schedule inspections on the 100-plus pieces of equipment we described earlier, then it’s time to consider a CMMS. Planning by keeping a manual PM schedule and the related inspection sheet takes too much time. I know some people that use their e-mail calendar to schedule PMs on their equipment. This does work as a reminder, but you still need to find and print the inspection sheets.

5. Is your to-do-list for equipment repairs growing longer?

Many people use a large desk calendar to plan their daily maintenance.

When the calendar gets full, then a notepad is used to record the overflow. As the pad gets fuller, planning the work to be done just becomes unmanageable.

I know places that use this method and they have a desk calendar full of maintenance jobs, along with the parts that need to be ordered. One notepad has a list of repairs to do later and another pad has a list of parts to order. A lot of us have been in this position. I re-

member the time it took to review and maintain these pads.

Creating and scheduling work orders in a CMMS saves time. Even if you’re not doing the job until later or until the parts come in, a work order can be created and be ready to go. Software companies have made updating and closing work orders so easy that these records can be completed in seconds. You won’t miss your pads!

6. Do you want safety information on the equipment accessible to crafts people?

Because of government safety regulations, trades people need to know the critical safety issues on equipment before they begin work. This information includes such things as lockout procedures.

In a CMMS, safety information is written directly on the work order automatically. This protects the employee and shows due diligence on the part of the employer.

7. Do you want to start tracking equipment costs?

I can imagine it would scare most people to death to think of trying to calculate the cost of maintaining equipment in a paper system.

Maintaining equipment history and costs have moved to the forefront of almost every organization, big or small.

Justifying equipment purchases and keeping within maintenance budgets are now a normal process of doing business.

8. Do your customers want reports?

We work with agriculture companies that have different growing operations.

Usually there is one maintenance facility that services them all. Many of their customers would like to see reports on the repairs to their equipment. They’d also like to have a schedule of when to bring their equipment in for servicing or annual overhauls. This very hard to do quickly in a manual system.

9. Are you going to start a certification process like ISO or HACCP? There are requirements in some accreditations that stipulate the use of maintenance software and electronic records. The people who audit these certification programs will want detailed data on the equipment and the planned preventive maintenance.

10. Finally, do all of your maintenance information and planned activities reside in the heads of one or two people?

This is very common in many smallto medium-sized companies. It’s also risky business. When people are on vacation, taking sick time, or leave a company for good, it causes a major hiccup in the maintenance department. Some information is lost forever.

So if you are experiencing one or more of these signs, it might be time to research a CMMS that will fit your current and future needs.

People worry that maintaining and updating a CMMS will take too much time. If you’re one of them, you need to step back and have a closer look at the actual time you’re spending looking after your paper filing system.

What we have concluded after working with companies that have made the jump to a CMMS is that it actually saves time.

Yes, it takes time to implement and learn the program, and this does cost money.

However, after a short time, you’ll wonder MRO how you got along without it.

PTDA’s Canadian Conference targets distributor needs da, accounting for 14% of Canada’s GDP — and provided an in-depth economic overview. He also emphasized new market and business opportunities for Canadian manufacturers and distributors.

According to Myers’ presentation, Canadian companies will continue to be challenged by the tightening of the US credit market and high levels of risk and uncertainty, but there are a number of opportunities for companies that build a strategy around differentiation. Organizations that continue to innovate and explore new markets, while focusing on what customers value and on eliminating waste, have an advantage as the economy stabilizes.

Following Myers’ analysis, delegates attended in-depth market briefings on: • Infrastructure with Martin Doble, global managing director, Hatch Engineering

• Mining with Tim Gallant, Iron Ore Company of Canada • Hydroelectric with Rick Everdell, project director, Niagara Tunnel Project, Ontario Power Generation, and • Aerospace and industrial engine manufacturing with Kevin Sodhi, commodities management global purchasing, and Antonio Columbo, key supplier initiatives, Pratt & Whitney Canada.

Attendees also listened to a presentation by Pat MacDonald, director of consulting for continuing education for Mohawk College; Ted Chisholm, vicepresident of finance and IT for BDI Canada Inc.; and Richard Ayuen, regional vice-president, Central Canada, for Kinecor LP, on the Industrial Careers Pathway program at Mohawk College in Hamilton, ON. A partnership between industry leaders and the college has yielded the unique Industrial Distribution Leader-

ship certificate program at Mohawk College, helping local distributors hone key skill sets in business principles, operational awareness, client service principles and leadership training/coaching.

A cohort of nearly 25 students is making its way through the program, which includes five core courses and a capstone course that provides an opportunity for students to apply the program’s lessons to their own work environments.

An energizing closing keynote address by Larry Smith, president and CEO of the Montreal Alouettes Football Club, concluded the Canadian Conference. Smith is an expert on successfully managing people within an ever-changing environment and shared the strategies he uses to bring out the best in a team. Smith emphasized the importance of developing a personal life plan that includes lifelong learning.

Next year, the Canadian Conference will be held June 3-5, 2010, in Montreal. The program is open to all PTDA members selling product in Canada — distributors and manufacturers — as well as non-members who qualify for MRO membership.

UNMATCHED ENGINEERING EXCELLENCE FROM THE SCHAEFFLER GROUP PowerTherm Induction Heaters Many rolling bearings and other rotationally symmetrical parts made from steel have tight fits on the 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 -

Driven to Extremes The constant evolution of capacity and efficiency in the field of power transmission increases the standard to 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 achieve extreme standards of performance.

Transport and Mounting Tool BEARING.MATE 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 by two 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 by crane. 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.

For additional information about PowerTherm induction heaters or BEARING.MATE, contact your local Schaeffler representative or visit www.fis-services.com
