Ruland has expanded its quick-clamping shaft collar line to accommodate sizes up to 75 mm and 3 in. The collars are designed for light-duty stationary or lowRPM applications that require quick positioning adjustments or frequent set-up changes where the use of tools is not practical. Quick-clamping shaft collars slide on the shaft smoothly and have easy access to the handle, allowing them to be removed or repositioned with little effort. When installed, the handle sits flush with the outside diameter, making the collar suitable for rotating applica-

Electro graphite material has long service life in food contact applications

Metallized Carbon’s Metcar Grade M-58 material has been FDA approved for use in food contact applications, allowing it to be used in dry-running, food mixer seals to provide lower seal friction and longer seal wear life. Dry-running mechanical seals are used on large, vertical mixers to seal the clearance between the agitator shaft and the mixer housing at the location where the shaft enters the top of the mixer. Metcar Grade M-58 is an electrographite base material that contains an additive to reduce friction and improve the dry-running wear rate. Available fully machined to the customer’s draw-

ing specifications, these primary seal rings can be used in temperatures between minus 30°F and plus 800°F. The material will also be useful in other machine part applications where an FDAapproved, self-lubricating material with low friction and long wear life is required.

In this vein, Meccano sets are one of the first things to come to mind. They were introduced in 1901 under the name ‘Mechanics Made Easy’. Suitable for kids aged five and up, today’s Meccano sets bear little resemblance to those some of us grew up with.

Modern sets are based on new assembly systems, new integrating materials and new technologies.

offers a Screws kit, Pulleys kit, Simple Machines kit, and Linkages kit; the latter comes with a 36-page activity book with innovative experiments and detailed explanations of the different technological principles applied.

There are plenty of other skill-building sets from various suppliers on the market, including the ubiquitous crystal radios, robot-building kits, electronics kits, and fluid power kits (some of these are very cool). A search for ‘mechanical toys for kids’ on the Internet will bring up plenty of links for these.

As the saying goes, it’s never too early to start. My grandson is going to have a lot of opportunities ahead of him, so I’m making sure these can include the possibility of learning a skilled trade. What are you going to do for the kids in your family?

Production capacity rate dragged down by manufacturing Ottawa – Canadian industries operated at 80.7% of their production capacity in the fourth quarter of 2012, down slightly from 81.1% in the third quarter, reports Statistics Canada. The decline was a result of lower capacity utilization in the manufacturing sector.

The manufacturing sector operated at 80.2% of its capacity in the fourth quarter, 2.1 percentage points lower than in the previous quarter. The decline was largely attributable to transportation equipment manufacturing and food manufacturing, though most other industry groups were also down. Of the 21 major groups in the manufacturing sector, 14 reduced their capacity utilization.

For food manufacturers, capacity use experienced its largest quarterly decline ever, falling from 78.1% in the third quarter to 73.8% in the fourth quarter.

Sharply reduced output of meat products was a key factor in the decline.

Lower production of agricultural, construction, mining and oil and gas field machinery pushed the machinery industry’s capacity utilization rate down 3.5 percentage points to 81.5%. In the fabricated metal products industry, capacity use fell from 83.5% to 80.0% as a result of weaker demand for metal work.

Capacity utilization was higher in the petroleum and coal products manufacturing industry and, to a lesser extent, the paper, chemical products and wood products industries.

In the non-manufacturing sector, there was a widespread increase in capacity utilization in the fourth quarter.

This compensated for part of the sharp decline in the manufacturing sector.

Increased crude petroleum extraction was the main reason for a 2.2 percentage point rise in the oil and gas extraction industry’s capacity use to 85.7%. An increase in metallic and non-metallic mineral mining pushed the mining and quarrying industry’s capacity utilization rate upward in the fourth quarter to 60.8%.

Compared with 2011, the capacity utilization rate of Canadian industries rose 1.3 percentage points to 81.0% in 2012.

This was the third consecutive annual increase, following an unbroken string of declines that started in 2005.

Advances in the capacity use in the manufacturing sector in 2012 was because of both higher output and lower production capacity, which resulted from an investment in facilities and equipment that was not sufficient to offset depreciation and other losses of assets.

DEADLINE FOR REPEAL OF ENGINEERING’S ‘INDUSTRIAL EXCEPTION’ EXTENDED Toronto – Those responsible for professional engineering work in Ontario in relation to production machinery or equipment now have longer to become licensed

by Professional Engineers Ontario (PEO).

On February 27, 2013, the Ontario government changed the date for the repeal of section 12(3)(a) of the Professional Engineers Act, the so-called ‘industrial exception’ to the requirement for a licence, to September 1, 2013, from the previously announced March 1. The government amended the date to allow additional time for those affected to become compliant.

“Extending the proclamation date from March 1, 2013, to September 1, 2013, will give Ontario companies more

time to prepare for the repeal of the industrial exception,” said John Gerretsen, the province’s attorney general. “This approach helps to protect public and worker safety and ensure smooth implementation for businesses.”

With the repeal of the industrial exception, individuals will have to be licensed by PEO if they do any act within the practice of professional engineering on machinery or equipment used to produce products for their employer in their employer’s facility.

Further information on the repeal, including instructional webinars, questions and answers, and a compliance tool kit employers can use to determine if they are affected by the change, is available on PEO’s website at www.peo.on.ca.

PUMP APPRECIATION DAY RECOGNIZES ‘HEART OF INDUSTRY’ Seneca Falls, NY – As the second-most common machine in all of industry (after electric motors), pumps are at the heart of everything. The world’s food, fuel, water and electricity are all processed and transported by pumps. To recognize this technology that is the heart of modern manufacturing, ITT Corporation’s Goulds Pumps brand observed the second-annual Pump Appreciation Day on April 9, 2013, to raise awareness of the value of pumps and the people and organizations that design, apply, install and service them.

In conjunction with Pump Appreciation Day, ITT Goulds Pumps donated $25,000 to the international Emergency Cardiovascular Care (ECC) Program, supported by the American Heart Association and its global partners. Events held on the second Tuesday of April each year include public recognition for recipients of the Heart of Industry and Pulse of Industry Awards, as well as open-house celebrations, cardiopulmonary resuscitation (CPR) training sessions and other educational events organized by the company’s sales team and distribution network.

BIG CLAW MAKES MARINE SALVAGE SAFER Trelleborg, Sweden – Watching the VB 10000 in action is quite a sight. Four giant white C-shaped truss structures with prongs at the bottom, dubbed ‘the Claw’, hang below two massive yellow arched trusses, spanning a pair of barges measuring 22 by 88.5 metres (72x290 ft). Bearings are critical to the unit’s operation.

The Claw is designed to reach hundreds of feet below sea level to remove sunken oil rigs from the seabed, in one piece and in one day. It’s also designed to lift the heaviest of loads. Although most oil rigs weigh between 1,000 and 3,500 tons, the VB 10000 can lift 6,000 tons in its current arrangement, and when in double grapple configuration, it can lift as much as 10,000 tons.

“It’s a game changer,” says Paul Van Kirk, project engineer with salvage specialist Versabar, which built the Claw.

“The industry has never seen anything like it. We can now retrieve platforms that have been knocked over by hurricanes without sending divers down to rig them up. That saves time and money.”

The materials used for bearings in several key locations are a significant part of the vessel’s innovation, says Van Kirk. Its predecessor, the smaller VB 4000, originally used bronze bushings in the critical

hinged gantry and barge connection. The bushings required regular maintenance for lubrication, wore out quickly and made a lot of noise. “When we started the design process for the VB 10000 we knew we wanted to use Orkot,” the Versabar engineer explains, referring to a lightweight and durable composite material developed and manufactured by Trelleborg. “It’s maintenance-free, easy to install, flexible and quiet. It just has a good track record.”

The VB 10000 uses Orkot material for its bearings in the gantry and barge connections and the sheaves in the blocks used to open and close the Claw. “The material is perfect for the job,” says Jason LaBorde, sales engineer with Trelleborg, who worked closely with Versabar’s engineers to get the heavy lifter built. “Orkot is designed for heavy loads and slow movements in a seawater environment. It’s both resistant to UV rays and corrosion.”

WESTERN CANADA TO CREATE 16,000 MORE JOBS FOR ENGINEERS BY 2020 Toronto – The job market for engineers is strongest in western Canada, according to data in a recently released report, Engineering Labour Market in Canada: Projections to 2020. Sponsored by Randstad Engineering in conjunction with Engineers Canada, the report shows that there is ‘strong expansion demand’ in the engineering sector in British Columbia, Alberta, and the prairie provinces. Here are some highlights from the report.

• Saskatchewan: Engineering markets are more cyclical and more varied than other provinces, but supply constraints are an issue. Resource projects are absorbing all available engineers – especially mining engineers. Saskatchewan is a small market with big project demands that come and go. Local post-secondary programs are not able to keep pace. Engineering immigration has been limited and strong current demand is reflected as Canadians from other provinces seek jobs and licensure in the province.

• Alberta: Along with BC, Alberta is the strongest engineering market in Canada.

There was strong engineering job growth in the past year, however there are ongoing shortages and recruiting challenges for engineers with five to 10 years of experience or specialized skills. Growth in enrolments in post-secondary programs for engineers has lagged behind national trends and may contribute to a tight labour market.

• British Columbia: One of the two strongest engineering markets in Canada, BC faces skills shortages and volatile markets in resource-related occupations like mining, metallurgical and petroleum engineers.

However conditions are more balanced for computer and industrial engineers. BC employers will need to source engineers from

other markets, however it is hard to attract them from other western provinces due to competitive compensation levels; * Manitoba: Expansion demands are concentrated in resource and utility projects. Construction, particularly in electrical generation and transmission, is a big driver. Labour markets are divided, with ongoing shortages and recruiting challenges for engineers with five to 10 years of experience or specialized skills.

On a national basis, expansion demand is expected to create an additional 16,000 jobs for engineers by 2020. Virtually all of these jobs will be west of Quebec, with the bulk of them in Alberta and British Columbia.

WORKFORCE CHALLENGES TO CONTINUE Ottawa – Over the next two decades, Canada and its regions will have to contend with the challenges of more and more aging baby-boomers leaving the workforce, according to a new commentary, Growth in Provincial Labour Productivity: A Problem from Coast to Coast, by Alicia Macdonald, senior economist with the Conference Board of Canada. The result will be slower growth in the economy while simultaneously adding to demand and expenditures for health care.

One part of the solution to slower growth would be to lift productivity – a sure-fire way to boost income per capita and help the country pay for those public services we want and need, says Macdonald.

She reports that while Canadians are hopeful for the future, the country’s past performance on the productivity front has not been strong. Numerous past studies have highlighted Canada’s poor labour productivity performance relative to the United States, but few have looked at the issue from a regional perspective. Productivity is not just a federal issue, she says.

This study looks at productivity among the provinces and finds that with just one exception (Newfoundland and Labrador), poor productivity growth is a problem that exists from coast-to-coast. With baby boomers contributing to slower economic growth and to rising health care expenditures across all regions, it’s vital that all provinces develop an agenda to boost their productivity growth, the report contends Over the 1998 to 2011 time period, the US posted average annual compound growth in labour productivity of 2.5%, while Canada posted average growth of 1.3%.

• Unmatched Quality

Problem: Why are the areas around our drives so noisy?

Solution: The problem is likely to be acoustical leaks. These are caused by direct air-path leaks or openings in noise guards around shafts used for visual inspection, or for cooling. These openings can reduce the effectiveness of noise guards.

For example, if a guard has the potential of a 40 decibel noise reduction, a small opening of just 1% of the total surface will cause the actual reduction to be only 20 decibels. Hearing protection is recommended in such areas.

BEARING UP F O C U S

Here are eight practical, field-proven tips for keeping your bearings and seals happy (Part 1 of 2).

T|

he industrial world revolves around bearings. We ask a lot of them. Here are some tips for keeping them turning and avoiding unpleasant surprises.

TIP 1

Press fitting new bearings. “A pump builder once claimed that the bearings they purchased were the wrong size. The new bearings the guys were trying to mount on the shaft were too loose,” recalls Jennifer Moritz, training manager, SKF Canada, Toronto. “We measured the shaft and proved that it was undersized. Then we asked how many times they had put new bearings on the shaft. They said ‘six’.

“Pulling bearings off shafts removes shaft material. You can only do three or four press fits before enough material has been scraped off that the bearing might not fit properly. You need a new shaft or you need to ‘metal it up’, or metal spray it, then turn it down for the right fit,” Moritz advises.

TIP 2 |

Proper shaft alignment.

Misaligning a motor to the opposing mechanical device can cause excessive stress and catastrophic bearing failure. “We had a large compressor motor come in for repair due to a shaft misalignment issue,” says Brad Stevenson, service manager, Gilbert-McEachern Electric, Brantford, ON. “The bearing had spun on the rotor shaft and damaged the end bell bearing journal [due to misalignment]. The bearing came apart and damaged the windings.

“Welding and machining was required on the rotor shaft and end bell, and the motor had to be rewound. This was a very costly repair due to a preventable mistake.”

TIP 3 |

Beware of textbook alignment tolerances regarding seals. Marcus Wickert, engineering division manager, NTN Canada, Mississauga, ON, emphasizes the interdependence of bearings, shafts, housings, seals and lubrication with the exposure of a common misapprehension about alignment. “Most people do not realize that even if bearings can tolerate a specific degree of misalignment, seals do not perform ideally under misaligned conditions.

“Take a common split pillow block.

Even though the spherical roller bearing may have a catalogue rating of 1.5 degrees of misalignment, the accompanying seals can rarely accept more than 0.5 degrees of misalignment. Misalignment causes uneven seal lip pressure, with heavy compression on one portion of the contact surface, while leaving the opposite side under minimal contact and open to contamination.

“If you spend time to align, you will ultimately also benefit from improved sealing performance.”

p11-17 MRO April13 Features.indd 11

TIP 4 |

Fig. 2

Check bearing shaft and housing fit. This is one of the most underestimated factors affecting bearing performance, according to NTN Canada’s Wickert. “An improper fit can allow the bearing to creep and often results in fretting wear or corrosion between the mating components.

“Fretting corrosion, a dark, rusty looking appearance, or mirror-like fretting wear, are key indicators of relative motion of two contact areas under load.

When excessive amounts of either of these are observed, make sure to check that component tolerances are within specifications prior to installing a new bearing onto worn components.”

TIP 5 |

Properly size and install journal bearings. Burlington, Ontario-based Thordon Bearings Inc. specializes in water-lubricated, non-metallic journal bearings. To help shops select and correctly install journal bearings, Thordon offers a bearing sizing program.

“We have a lot of plants that install bearings themselves. There are things that shops sometimes get wrong. If we run into a problem, it may be because the appropriate bearing material was not used, or it was not sized and installed properly,” says Keith Brand, business development manager for pumps and industry at Thordon.

“The sizing program takes a few minutes to fill out. It includes inputs for the application, temperature, pressure, vertical or horizontal pump, and bearing installation type. Once you fill in all this data, you will get a printout of how to size and machine the bearings.”

Don’t be shy about asking for help, Brand says. “We can assist you. This is especially important if a shop is doing this work for the first time.”

TIP 6 |

Use seals for highmoisture applications.

To protect gearboxes against moisture damage, Gilbert-McEachern Electric’s Stevenson recommends using the proper lubrication, keeping the lubrication level up, changing the lubricant regularly and keeping moisture from getting inside.

Concerning the moisture challenge, SKF Canada’s Moritz advises, “I am against employing unnecessary expenses and fancy solutions when properly sealing the bearing cavity can resolve so many problems. Changing the bearing material doesn’t prevent moisture and/or particle ingress. Only proper and effective sealing – a comparatively cheap solution – can eliminate the root cause.

“A simple V-ring seal is shockingly effective at contamination prevention, costs only a few dollars and takes little space to implement.”

Fig. 1: Misalignment of a motor with neighbouring parts can cause catastrophic bearing failures. Fig. 2: Maintaining proper lubricant levels and using the right seals will prevent moisture damage. Fig. 3: Lack of lubrication will result in overheating and bearing destruction.

TIP 7 |

Do not under-lubricate.

It shouldn’t be allowed to happen, but letting bearings run dry is a common oversight. “A lot of people do not have a good grease schedule,” SKF Canada’s Moritz observes.

Gilbert-McEachern Electric’s Stevenson describes some of the damage he has seen due to under-lubrication. “In certain circumstances the inner race of the bearing has worn the bearing journal on the rotor shaft. This requires weld repairs and machining to get the journal back to the correct bearing tolerance. In some cases the bearings have completely come apart. The balls of some bearing have gone so long without the proper lubrication that they have worn flat.”

Prevention is simple, Stevenson says, “Perform routine lubrication using the proper lubrication specified by the motor manufacturer.”

TIP 8 |

Do not over-lubricate.

On the flip side, attacking bearings with the old grease gun creates

its own problems. Stevenson recalls two choice failures. “One customer lubricated the non-drive end bearing without removing the drain plug in the bottom of the end bell. The grease accumulated inside the bearing cavity, eventually filled the end bell and leaked into the winding/stator of the motor.

“Over-lubrication can also fill the air gap of the rotor stator and lock up the motor. Certain greases can carry the electrical current from the windings to the motor frame, causing it to go to a grounded state.”

One solution is to reduce the frequency of lubrication, says Stevenson. If there is a drain plug, remove it while lubricating the bearing. This lets contaminated grease drain from the bearing cavity and allows the new grease to access the bearing properly.

Understanding roller bearing failure modes and mechanisms goes a long way towards avoiding costly bearing failures.

Bearing maintenance takes know-how

BY STEVE GAHBAUER

There are several causes of failures that bearings need to be protected from, including fatigue, wear, corrosion, electrical erosion, plastic deformation, and fracture and cracking.

U

nderstanding what triggers and propagates different types of damage to bearing surfaces can lead to methods that reduce the incidence or severity of such damage.

Over-rolling of solid particles can produce surface indentations of raceways in rolling/sliding lubricated contact areas. These indentations are known to increase the risk of contact failure. The failure process may be influenced by the amount of sliding present at the contact.

For low sliding conditions, typical for rolling bearings, the failure process is dominated by film thickness reduction and surface distress around the shoulders of the indentation.

Keep in mind that indentations in rolling/sliding lubricated contacts repre­ sent a significant risk for the service life of bearings. Bearing deterioration and consequent failure can have many forms and several degrees of severity.

In an in-depth technical paper on bearing failure modes and mechanisms, SKF Canada’s Jennifer Moritz presented a comprehensive overview at an education workshop last fall, convened by the Hamilton, ON, section of the Society of Tribologists and Lubrication Engineers (STLE).

According to Moritz, failure modes can be classified into failures resulting from fatigue, wear, corrosion, electrical erosion, plastic deformation, and fracture and cracking.

Fatigue is manifested visibly as a flaking of particles from the surface. It is caused by repeated stresses developed in the contacts between the rolling elements and the raceways. Wear is the progressive removal of material resulting from the interaction of the asperities of two sliding or rolling/sliding contacting surfaces during service. Wear can be abrasive or adhesive.

Corrosion (rust) is a chemical reaction on metal surfaces. It can be caused by moisture or by friction. The latter is manifested by fretting or false brinelling.

Frictional corrosion is a chemical reaction activated by relative micro movements between mating surfaces under certain conditions. These micro movements lead to oxidation of the surfaces and become visible as powdery rust and/or loss of material from one or both mating surfaces.

Electrical erosion is the removal of material from the contact surfaces caused by the passage of electric current – either excessive voltage or current leakage. Excessive voltage creates craters of up to one-tenth of a millimetre.

Current leakage creates smaller and more closely positioned craters. There is usually a dark grey discolouration.

Plastic deformation occurs when the yield strength of the bearing material is exceeded. Typically this happens in two

p11-17 MRO April13 Features.indd 13

different ways: on a macro scale, where the contact load between a rolling element and the raceway causes yielding over a substantial portion of the contact

footprint; or on a micro scale, where a foreign object (debris) is over-rolled between a rolling element and the raceway, and yielding occurs only over a small part of the contact footprint.

Fracture and cracking happens when there is a stress concentration in excess of the material’s tensile strength.

Fracture is the result of a crack propagating to the point of complete separation of a part. Cracking, which normally precedes fracture, is the incomplete separation of material under stress conditions.

To increase the understanding of the failure process and to develop preventive measures, SKF engineers carried out a detailed analysis of the dynamic behaviour of indentations in rolling/sliding heavily loaded lubricated contacts. They have created advances to bearing theory models that agree with experimental results.

Their work also points out the importance of cleanliness, proper bearing mounting,

and appropriate lubrication to reduce the risk of surface damage.

Senior scientists of the SKF Engineering & Research Centre in Holland suggest three cardinal measures that reduce the risk of generating surface indentation: 1. Keep the lubricant as clean as possible and check for damaged seals.

2. Follow the manufacturer’s mounting recommendations.

3. Always maintain a good lubricating film by selecting the proper viscosity for the operating conditions. This minimizes surface distress and extends bearing life.

Detecting misalignment, preventing corrosion and limiting contamination are all important keys when improving bearing health.

earing health can be monitored through the use of infrared temperature measurements, vibration and acoustical signals, and oil analysis. Failure mode analysis by itself is especially useful in diagnosing root causes of problems after the damage is done.

Through the prudent use of temperature and vibration-monitoring equipment, routine oil analysis, lubrication system evaluations and machine operational performance reviews, bearing distress may be identified and evaluated before catastrophic failure occurs.

Being able to properly identify damage resulting from improper installation, pitting, fatigue, abrasion and corrosion is the key to diagnosing root causes of bearing problems. Some typical problems include false brinelling, true brinelling, misalignment, fretting corrosion, contamination and fatigue.

False brinelling: Caused by vibration resulting in movement of the rolling element against the raceway in stationary bearings. Damage appears as linear or elliptical wear marks in an axial direction at each ball position. It can be controlled by eliminating axial movement and using lubricants containing solid additives.

True brinelling: Appears as indentations in the raceway at the same interval spacing as the balls. It will result in increased bearing vibration and can lead to fatigue failure. It is different from false brinelling in that the indentations are not just surface marks. True brinelling is caused by a severe impact to the bearing, such as by dropping it or striking it with a hammer. Static overload can also be a cause. Proper installation will cure most causes of true brinelling. Paying attention to static load ratings is important too.

Misalignment: Appears as wear path not parallel to the raceway edges. It is caused by many things, most commonly bent shafts or shafts that are not properly aligned, or improper installation. It is best fixed by properly aligning shafts and through good installation practices, including the use of precision locknuts.

Fretting corrosion: Characterized by micro-motion between parts where fit is just short of tight enough. It appears as brown rust, usually between the housing and the outer ring or the shaft and the inner ring. It can be prevented by assuring proper fit upon installation. Fretting corrosion can also affect shaft and huband-spline shaft connections. In these applications, the use of solid lubricants can cure the problem.

Contamination: Raceways and/or roll-

Preventive maintenance tips 1. Oil analysis – a quick visual examination of the oil and oil filter may be all that is required to determine that a problem exists. A thorough oil analysis can provide useful data to assist in diagnosing bearing or machine distress. As a min-

imum, the following should be supplied: • Particulate density and particulate breakdown • Viscosity and water contamination • Chemical breakdown.

2. Operational data - another important source of diagnostic information is unit operational data, such as: • Period of load or speed changes, recent maintenance • Performance of related machinery, vibration data/analysis.

In a perfect world, hydrodynamic bearings theoretically have an infinite life. Equipment operators know that their world is far from perfect.

By taking a forensic approach to plain bearing failures, the operator can uncover and correct system-related problems, and ultimately increase machine availability and output, and thereby decrease costs.

ing elements will bear slight indentation marks in random patterns. It will often lead to early spalling failure. It is caused by dust or dirt particles or other abrasive substances introduced from the environment, or by a contaminated work area or lubricant. Clean tools, work areas and lubricants will solve the problem. Keep bearings in the original packaging until it is time to install them.

Normal fatigue (spalling failure): Indicated by pitting of raceway or rolling element surfaces.

Progressive wear results in increasing vibration and leads to bearing failure. It is caused by excessive preloading, tight inner ring fits and excessive load. Normal fatigue is also the mode of failure for the 10% of bearings that operate for their calculated service life.

ing with surplus houses because they deal with stuff that comes from all over the world, so I think they tend to turn a blind eye as to whether the product could be counterfeit if the packaging looks close.”

The battle against counterfeits Bearing manufacturers around the world are working to fight the growth of fakes, while Canada is one of the latest trouble spots, as the RCMP recently found.

BY REBECCA REID

Users sometimes are unaware of the significant risks associated with using counterfeit bearings. Fake bearings can damage equipment and even cause personal injury.

T

imken Canada received an ominous phone call in July last year from a constable at the Royal Canadian Mounted Police (RCMP), asking about counterfeit bearings.

It turns out the Canada Border Services Agency (CBSA) had intercepted a full pallet of bearings at Toronto’s Pearson International Airport in a shipment from China.

“They sent some photographs of the cartons and the external packaging, and asked if we could determine if they were counterfeit,” recalled Evan Boere, business development manager at Timken Canada in Mississauga, ON. “Unfortunately to the trained eye – or the reasonably trained eye – the differences can be hard to spot, but the actual cartons looked wrong enough to raise suspicion.”

All Timken products come in black and orange packaging with a hologram for counterfeit protection. Boere noted the packaging on the suspect shipment was missing a hologram and the barcoding was wrong.

“Those were the first indications,” he said. “Constable Gill asked if we could do some analysis – there were enough telltale signs – so we sent the bearings to our manufacturing plant in St. Thomas, ON, that has a lab.”

The bearings conformed to Timken’s standards in terms of dimensions, surface hardness and weight, but because of the scoring marks on the cone raceway, the product was sent to Timken’s metallurgical lab at its Canton, OH, headquarters for further analysis.

Once they cut it open, it was obvious the bearings weren’t genuine. They

p11-17 MRO April13 Features.indd 16

were through-hardened, not case-hardened, and the materials were wrong, Boere explained.

Imported from China Tracking down the perpetrator, however, is challenging.

“That gets a little difficult,” he said. “It’s very difficult to determine the manufacturing source, but they came in from China.”

“We have to do it ourselves,” added Daniel Szoch, program manager at Timken in Canton. Szoch heads up the company’s global anti-counterfeiting operations. The authorities in China usually don’t take the lead in these investigations, he explained. The onus is on the manufacturer to track down the guilty party and point the authorities in the right direction. It can be costly and time consuming.

“Users sometimes are unaware of the significant risks associated with using counterfeit bearings,” Szoch said.

“If installed, these fake bearings can damage equipment and even cause personal injury.”

This was the second time in the past year Timken has been notified of counterfeit bearings from China.

“We get a phone call from one of our distributors saying they had unknowingly purchased a bearing from a source they thought was trustworthy,” Boere said. The source was a surplus house.

“We spoke to the principle at the surplus house and he was very good at telling us where he sourced them in China.

We tried tracking them down but we weren’t successful,” he added.

“The products were marked as ‘made in the USA’ but they came from China at a really fantastic lead price. It’s interest-

Improving detection The World Bearing Association has embarked on a mission to educate customs officials around the world about ways to spot counterfeit bearings. In fact, the organization was formed specifically to tackle the problem and has launched a Stop Fake Bearings campaign.

These counterfeits don’t just have an impact on the company’s bottom line; the shoddy performance of these fakes in markets such as automotive can cost people their lives, according to the association.

Boere has conducted education sessions for border officers in Canada. Yet, officials don’t have time to thoroughly check every shipment and even then, fakes would still slip through the cracks, he said.

Scott Lynch, president of the American Bearing Manufacturers Association (ABMA), says Chinese officials have seized 2.2 million bearing products since 2009, and a customs seizure in Long Beach, CA, in 2009 unearthed US$750,000 worth of fakes mimicking four different brands.

Szoch says Timken works with customs officials in each region to determine the flow of their products in and out of the country. “They’ve been more than forthcoming in sharing that kind of information,” he noted.

All bearing manufacturers have been victimized, with the top-selling products being copied most often, he added.

Timken plans to improve detection rates by adding an extra layer of security to its packaging. The hologram will include a QR code; the customer can scan the box to determine authenticity.

When asked if Timken is concerned they could be targets of packaging theft, Szoch said the company pays close attention to any scenario where it could happen, but it isn’t likely. The company doesn’t reuse any of its packaging and customers in the OEM supply chain purchase directly from the company, Szoch explained.

“This phenomenon has more of an impact on our aftermarket industrial distribution business,” he noted. All buyers can do is make sure they purchase from

authorized distributors and notify the manufacturer directly if they suspect a product is counterfeit.

In that regard, some stakeholders are urging the government to keep counterfeit parts out of the supply chain.

“We understand there are customs measures that exist in other countries that are reasonably effective in detecting counterfeit shipments,” said Ingalill Ostman, senior vice-president, group communications and government relations at the SKF Group, based in Gothenburg, Sweden.

“Thankfully, we have no reason to believe that this is a substantial or widespread issue in Canada,” she noted. “That being said, SKF Canada views even the rare instances of counterfeit products that have arisen in this country as serious.”

“SKF believes Canadian law could be strengthened to better protect the borders and market against counterfeit products.”

Ostman isn’t alone. A June 2012 report from the Canadian Intellectual Property Council, called ‘Counterfeiting in the Canadian Market: How do we stop it?’ says Canadian border enforcement needs to be strengthened. It also called for the creation of an intellectual property crime task force.

In March, the federal government enacted the Combating Counterfeit Products Act to help protect the Canadian economy from the health and economic threats presented by counterfeit goods coming into Canada.

The Act provides the CBSA with the authority to take action against the commercial movement of counterfeit goods at the border, and will also include new criminal offences for commercial trademark counterfeiting. It will also allow Canadian businesses to file a request for assistance with the CBSA, in turn, enabling border officers to share information with them regarding suspect shipments.

The Act, which covers only commercial shipments, will bring Canada into compliance with international obligations under the Anti-Counterfeit Trade Agreement (ACTA), signed last year.

CAVEAT EMPTOR The RCMP says buyers need to consider the four P’s when making purchases. People can be easily fooled, even purchasers at an aftermarket distributor.

Packaging | Examine the packaging for quality, spelling errors, incorrect fonts, lack of the supplier’s standard security measures, like Timken’s holograms, and incorrect barcodes.

Price | If the price is too good to be true, it probably is.

However, some counterfeiters do have the audacity to sell their shoddy knock-offs at full-price.

Product | Examine the product for signs of poor-quality manufacturing.

Place | Be wary when purchasing online; ensure the dealer is reputable. Most counterfeit parts come from China, but Taiwan, India, Pakistan and Malaysia are also known to ship fake parts.

Head to U

Toe

sing your head on the job is just one way to keep safe, but it’s also important to know that standards are helping reduce the severity of a wide range of injuries, from head to toe.

Your eyes face risks on a daily basis.

On many worksites, the risks to your eyes and head are greatly increased, calling for personal protective equipment such as hard hats and safety glasses.

Damage to eyesight, a significant head injury or an acquired brain injury can also have devastating long-term impacts. The proper use of protective eyewear can help to avert a disaster. In this regard, the Canadian Standards Association (CSA) has two standards – Z94.1 Industrial Protective Headwear and Z94.3 Eye and Face Protector – aimed at helping to protect the eyes, faces and heads of workers on the job.

Each year the Association of Workers’ Compensation Boards of Canada (AWCBC) publishes the National Work Injury, Disease and Fatality Statistics, documenting the nature of loss-time and fatal incidents in the Canadian workplace. CSA Group uses these numbers to help determine where it needs to place a greater focus on improving the lives of Canada’s workforce.

Every year, more than one million North Americans sustain some kind of brain injury, leading to about 110,000 deaths, according to Dr. Rolf Gainer, chief executive officer of the Neurologic Rehabilitation Institute at Brookhaven Hospital in Tulsa, OK, and the Neurologic Rehabilitation Institute of Ontario in Toronto. The leading causes are falls, motor vehicle crashes, bicycle crashes and sportsrelated injuries. Work-related incidents account for about 15% of all brain injuries.

According to the Brain Injury Association of Canada, it is estimated that the direct and indirect costs associated with traumatic brain injury are $14.7 billion annually in Canada. Brain injury can vary from mild (concussion) to severe (deep coma). Depending on the severity of the injury, some victims may recover after a period of rest, while others will require a lifetime of support.

Since 2003, CSA Group has tracked various benchmarks though its Key Performance Indicators (KPIs). In 1994, more than 25,000 eye, head and face injuries were recorded in Canada. By 2007, that number had dropped to about 18,000, according to the AWCBC’s 2008 report. The introduction and revisions of several CSA standards during that time period led to this decrease.

Here are some useful tips for avoiding eye, face and head injuries:

p11-17 MRO April13 Features.indd 17

• Use the right combination of certified personal protective equipment • Beware of flying objects, such as bits of metal, glass, stone or wood • Always employ safe tool-handling practices • Beware of chemical splashes, sparks and slag from welding and cutting • Beware of pipes and wires sticking out of walls and objects hanging from ceilings • Always practice safe work procedures • Report unsafe conditions as quickly as possible to your supervisor or employer.

Keeping your feet and toes safer Foot and toe injuries – those that are crushed, amputated or punctured – represent a significant portion of lost-time injuries in the workplace.

In 1970, CSA introduced a standard for protective footwear (Z195) in 1970. Since 2002, when the sixth edition of this standard was published, the number of foot and toe injuries on worksites across Canada has declined by thousands each year.

Work-related foot injuries come in two basic categories: foot injuries from punctures, crushing, sprains and lacerations; and foot injuries resulting from slips, trips and falls. These account for 10% and 15% of all reported disabling injuries respectively. Slips and falls do not always result in a foot injury, but lack of attention to foot safety plays an important role in their occurrence.

CSA Group’s KPIs show that in 1993, nearly 16,000 foot injuries were recorded in Canada. By 2007, that number had dropped to less than 12,000, according to the AWCBC’s report, National Work Injury, Disease and Fatality Statistics (2007). The introduction and revisions of several CSA standards during that time period helped to speed this decrease.

There is no workplace where a worker is immune to foot injury. However, the hazards differ according to the workplace and the types of tasks the worker does. The first step in developing a strategy to reduce foot problems is to identify the relevant hazards at the workplace.

Such hazards should be assessed in each workplace, no matter how safe or how dangerous it may seem.

Foot injury prevention Job and workplace designs also have the potential to increase foot safety in workplaces that are specifically hazardous.

Separating mobile equipment from pedestrian traffic and installing safety mirrors and warning signs can decrease the number of accidents that might result in cut or crushed feet or toes.

Proper guarding of machines such as

saws can avoid cuts or severed feet or toes. Effective housekeeping reduces the number of accidents at workplaces. For example, loose nails and other sharp objects, and littered walkways, are hazards for foot injury.

Tips for safety shoes A safety shoe’s steel toecap should cover the whole length of the toes from tips to beyond the natural bend of the foot. A soft pad covering the edge of the toecap increases comfort. If the toecap cuts into the foot, either the size or style of the footwear is incorrect.

Soles come in a variety of thicknesses

and materials. They need to be chosen according to the hazards and type(s) of flooring in the workplace. Uppers of protective footwear come in a variety of materials. Selection should take into account the hazards, and individual characteristics of the worker’s foot. A steelmidsole that protects the foot against penetration by sharp objects should be flexible enough to allow the foot to bend.

Ensure that your boots are CSA-approved and certified to the type of activity you will need them for.

Why preventive maintenance must become mandatory.

Overcoming PM challenges I

have the opportunity to visit many industrial facilities in the run of a year and get to see many common problems as I work with their maintenance departments. A common issue I see is maintenance departments trying to find the time to do preventive maintenance (PM).

Why is finding the time for this important task a problem? There are several reasons, however, the top three are: 1. Production is not releasing the equipment for maintenance work. 2. There are not enough available maintenance labour hours. 3. Maintenance is too busy repairing breakdowns. Let’s look at these in order.

1. Production schedules: Although the maintenance department can request to have the equipment released for preventive maintenance, the production department may refuse in order to meet customer demands.

Beyond expressing the importance of completing preventive maintenance, there is little maintenance can do if the equipment is not released. In situations like this, a maintenance department needs to become more creative. Here is a solution for this problem that other North American facilities have used: Break the PMs into two categories – running and downtime.

Running PMs are tasks that can be done during normal equipment operation.

Running PMs require attention to detail.

Abnormal noises, heat, vibration, etc., indicate problems that either need to be addressed immediately or can wait for scheduled downtime.

Downtime PMs are tasks that need the equipment out of service. When there is limited time available to complete the necessary checks, these PMs need to be very focused. The available time needs to be used to thoroughly check the equipment components that can cause breakdowns.

It is my experience that when these two PM categories are adopted, four things occur:

p18-19 MRO April13 Columns.indd 18

©iStockphoto/Thinkstock

a) PMs become more focused. b) The time the equipment needs to be out of service for preventive maintenance is reduced. c) Production is more likely to release equipment because of the reduced time it takes to do the PM. d) As a result, the equipment becomes more reliable.

2. Not enough maintenance hours: Everyone will agree about the importance of doing preventive maintenance.

Supervisors will develop basic and detailed checklists and determine the frequency the PM must be performed and the labour hours required to carry out the PM task.

However, when everything is ready to implement, maintenance realizes that they do not have enough available manhours to complete the scheduled PMs. This lack of hours comes from two causes. a) There are physically not enough labour hours available. For example: there are 100 labour hours of preventive maintenance to do, but only 80 labour hours available to do them.

This is happens quite regularly in nonproduction environments like universities, laboratories and hospitals, where breakdowns are not a big issue. Therefore, these types of facilities must decide to hire more maintenance personnel or reduce the number of PMs they perform. The latter is usually the case in 90% of these types of facilities. b) Maintenance procedures and execution of the planned maintenance are ineffective.

One thing that is very evident is the ineffectiveness of PM procedures. Checklists are almost always out-of-date and vague.

Simply having a checklist is not enough; procedures need to tell tradespeople how things are to be checked and what to look for. Then proper scheduling must be developed, making sure labour, parts and materials are available at PM time.

3. Maintenance is too busy repairing breakdowns: There are too many

breakdowns, creating a Catch 22 situation – whether to respond to breakdowns or perform preventive maintenance.

There are many companies that want to change this culture. Maintenance supervisors and tradespeople get totally consumed just keeping production equipment running. In these cases, the breakdown-to-PM ratio is very skewed.

Preventive maintenance doesn’t get put in the back seat but gets put in the trunk and is virtually forgotten. Changing this type of maintenance culture takes a lot of work.

Why do preventive maintenance?

To strengthen the importance of completing maintenance tasks in whatever environment you work in – production or nonproduction – I want to review the reasons why we must do preventive maintenance.

Here are the top six reasons: 1. Legal: There may be federal, provincial or local legislation that requires you to do preventive maintenance. In particular, look into anything where emissions can damage or harm people or the environment. Preventive maintenance on pumps, tanks, or chemical systems that control emissions from the plant, must be maintained to ensure the safety of the public and environment. As well, insurance policies may require electrical substation equipment to be inspected and thermographic scans to be taken yearly.

2. Safety: Protecting the safety of all staff within a facility is the responsibility of the owner of the company. Companies are morally responsible to protect their employees.

Government occupational health safety divisions are given the responsibility to enforce the laws that protect people in the workplace. Failure to do preventive maintenance, where it results in the injury of personnel, will prompt officers to investigate and possibly fine, or charge, supervisors and managers under provincial laws.

3. Operational: Keeping equipment up and running is what maintenance departments are supposed to do. Preventive maintenance is the key to make this a daily reality. No one can dispute that regular, effective preventive maintenance will reduce failures.

4. Economical: There is no doubt that prolonging the life of equipment and maintaining its reliability will save a company money. Reducing the cost per unit helps make a company more profitable.

5. Customer demands: Customers of all types are demanding more quality, better delivery, improved service and lower prices. Therefore, the reliability of equipment is most important to serve these needs. In OEM auto parts manufacturing, for example, the auto companies require the equipment that builds their parts to be inspected at very specific intervals. In other words, if XYZ Company produces OEM parts for Toyota, then the equipment that produces these parts must have regular preventive maintenance.

6. Maintaining certifications: Whether the certification is external like that from ISO, or a customer certification, your preventive maintenance plan will be reviewed in an audit. Both internal and external auditors score the PM records for completeness and for being performed on time. They check for signatures of the maintenance person, as well as the execution of follow-up work orders from abnormalities found during the preventive maintenance routines.

Let’s face it, most of us can do a better job at scheduling and performing preventive maintenance. These six reasons to do preventive maintenance make it clear: PM is no longer an option – it is mandatory.

Five basic rules for safe maintenance

It is very important to remember that exceeding the scope of one’s own skills and competence may result in accidents.

BY SIMON FRIDLYAND

M

aintenance is a high-risk activity because it often requires working alongside a running process and in close contact with machinery. During normal production operations, automation typically diminishes the likelihood of human error that can lead to accidents. However, in maintenance activities, contrary to normal operation, direct contact between the worker and machine cannot be reduced substantially, as maintenance is an activity where workers need to be in close contact with processes and machinery.

Maintenance often involves unusual work, non-routine tasks, and it is often performed in exceptional conditions, such as in confined spaces, for example. Maintenance operations typically include both disassembly and reassembly, often involving complicated machinery. This can be associated with a greater risk of human error, increasing the accident risk.

Working under time pressure is also typical for maintenance operations, especially when shutdowns or high-priority repairs are involved.

As a result, there is a high risk of accidents related to maintenance activities.

Here are some of the most common: • Crushing by moving machinery or unexpected machine start-up • Falls from heights or accidents involving falling objects • Electrocution, electrical shocks or burns • Confined spaces resulting in asphyxiation • Explosions and fire.

In order to mitigate the risk to maintenance personnel, there are five basic rules for safe maintenance.

1. Planning. Maintenance must start with proper planning. A risk assessment must be carried out and workers should be involved in this process. Issues to be covered at the planning stage are: a) The scope of the task – what needs to be done, and how it will affect other workers and activities in the workplace. b) Risk assessment – potential hazards have to be identified (e.g., dangerous substances, confined spaces, moving parts of machinery, chemical substances or dust in the air), and measures need to be developed to eliminate or minimize the risks. c) Permits to work and lock-out systems. d) The time and resources that the activity will require. e) Communication between maintenance and production staff, and all other parties concerned. f) Competence of the employees and adequate training.

Employers need to ensure that workers have the skills that they need to carry out the necessary tasks, are informed about safe work procedures, and know what to do when a situation exceeds their competence.

2. Making the workplace safe. The work area needs to be secured by preventing unauthorized access, by using

p18-19 MRO April13 Columns.indd 19

©iStockphoto/Thinkstock

barriers and signs, for example. The area also needs to be kept clean and safe, with power locked-out, moving parts of machinery secured, temporary ventilation installed, and safe routes established for workers to enter and exit the work area.

Warning cards should be attached to machinery, with the date and time of lock-out, as well as the name of the person authorized to remove the lock. This way, the safety of the worker performing the maintenance on the machine will not be jeopardized by another worker inadvertently starting it up.

If possible, guards should be designed so as to allow minor maintenance on the machines without removing them. If the guards must be removed or deactivated, then lock-out procedures should be followed. Maintenance workers must be trained on how, and under which conditions, safeguards may be removed.

3. Use of appropriate equipment.

Workers involved in maintenance tasks should have the appropriate tools and equipment, which may be different from those that they normally use. Considering that they may be working in areas that are not designed to have people working in them, and that they may be exposed to a variety of hazards, they must also have appropriate personal protective equipment (PPE).

With respect to the equipment and tools to be used, employers should ensure that: • the right tools and equipment for the job are available (together with instructions in using them, if required) • they are in an appropriate condition • they are suitable for the work environ-

ment (e.g., no sparking tools in flammable atmospheres), and • they have an ergonomic design.

All personal protective equipment must: • be appropriate for the risks involved, without the equipment itself leading to any increased risk • correspond to existing conditions at the workplace • take account of ergonomic requirements and the worker’s state of health • fit the wearer correctly after any necessary adjustment.

4. Working as planned. Safe work procedures have to be communicated and understood by workers and supervisors, and applied correctly. The work should be monitored so that the agreed safe systems of work and jobsite rules are observed.

Maintenance is often carried out under pressure – for example, when a fault has brought the production process to a standstill. Safe procedures need to be followed, even when there is time pressure. Shortcuts could be very costly if they lead to accidents, injuries or damage to property.

Procedures need to be in place for unexpected events. Part of the safe system of work should be to stop work when faced with an unforeseen problem or a problem exceeding one’s own competence.

It is very important to remember that exceeding the scope of one’s own skills and competence may result in accidents.

5. Final check. The maintenance process needs to end with checks to make sure that the task has been completed, that the machine under maintenance is in a safe condition, and that all waste material that has been generated during the maintenance process has been cleaned away. When all is checked and declared safe, then the task can be signed off, and supervisors and other workers can be notified.

This final step also involves completing a report, describing the work that has been performed and including comments on any difficulties that have been encountered, together with recommendations for improvement. Ideally, this should also be discussed at a staff meeting where the workers involved in the process – as well as those working around them – can comment on the maintenance activity and come up with suitable suggestions to improve the process.

Statistics shows that around 15% to 20% (depending on the province) of all accidents and 10% to 15% of all fatal accidents are related to maintenance operations. Maintenance workers, please be safe!

ment in the bearing. Load rating and rating life are increased significantly as a result. The cage comprises two cage rings lying one inside the other and joined together. The crosspieces of the inner cage guide the roller elements. At the same time, these retain the roller elements in the bearing, even when the bearing ring is removed. This means that the bearing is much easier to mount, as no separate device is required to help prevent the roller elements from falling out.

Cooper Roller Bearings has increased the load capacities of many of its split roller bearings, with L10 life that is 23% to 135% longer.

The 01E (medium-duty) and 02E (heavy-duty) bearings are interchangeable with the company’s 01 and 02 series bearings, yet provide up to 29% more radial capacity and 16% to 90% more axial load capacity. The bearings are completely split to the shaft, which eliminates the need to disassemble all components on a shaft for service or replacement. They feature the same sealing and energy-efficiency as their counterparts in the 01 and 02 series and share the same exterior dimensions, giving users more capacity in the same space. Rugged brass cages make them suitable for underground applications and other challenging environments. The bearings are available with bore sizes from 160 mm to 300 mm (6.5 in. to 12 in.). Typical applications include mining equipment (e.g. bucket wheel excavators, crushers, stacker reclaimers), industrial fans and conveyors, and power generation.

Koyo offers ball bearings with both contact and non-contact sealing options. Its RD lightcontact sealed ball bearings provide both low torque and tight sealing. The ingress of contaminants and moisture is prevented by several design features. The inner seal lip prevents the leakage of grease by directing it towards the bearing interior, while clearances between the inner ring and lip seals form a labyrinth, which improves seal tightness. Also, the angled inner ring and seal outer lip help keep contamination out of the bearing, and the protuberance at the tip of the outer lip improves the seal’s tightness. Foreign materials are prevented from entering the bearing interior by centrifugal force resulting from rotation.

Tschudin & Heid linear roller cages and guides are components for machine, instrument, tool and fixture applications. The design of the rollers and cages allows the displacement of moving parts in an axial direction through the use of parallel shafts and sleeves, while no radial movement is possible. This construction is particularly appropriate in cases where heavy loads must be moved in confined spaces without loss of precision or rigidity. As the use of rollers instead of balls results in line contact with the guide, rather than point contact, pre-load at assembly can be kept low, which produces a low surface pressure between the rollers and guides. The rollers are arranged within a plastic or metallic cage in spiral fashion, spread over the entire surface area of the shaft and sleeve, leading to long service life of the guide unit. This is a low-maintenance unit, requiring only a thin lubricating film for normal operation.

The work gloves, which are resistant to abrasion and punctures, can be used alone or as a two-part system that mates the gloves with tools or pieces of equipment wrapped with Gripping Material tape. When used as a two-part system, the gloves can provide up to a 270% improvement in friction. They are suitable for anyone who needs a better grip, especially in wet or oily conditions.

Fortress Interlocks has added the E1 Extracted Key Adaptor to its amGard range of modular safety gate switch interlocks. The E1 ensures that the door to hazardous machinery cannot be opened without removing the safety key, and the machinery cannot then be restarted until the key is returned. The mechanism is designed to trap an actuator in the head unit until the key is removed, which then allows the gate to swing over the keyhole. While the actuator remains out of the head, the gate remains over the keyhole, preventing the key being returned to the lock. The device ensures a specific sequence of operation and can be stacked or combined with other adaptors; up to five key adaptors can be used in one configuration.

It works with access key and safety key adaptors, Fortress amGard LOK or Stop bodies, and is suitable for either hinged or sliding door applications.

What’s new in seals and gaskets

One-piece V-cup seal reduces part cost

Minnesota Rubber and Plastics’ redesigned piston V-cup seal combines two components into a single part while maintaining part function and product life. Used in fuel assembly applications, it provides improved seal life while reducing manufacturing and assembly costs. A fuel-resistant fluoroelastomer material enables the seal to withstand the harshness of extended fuels. In addition to providing the needed fuel resistance, the fluoroelastomer provides good flex fatigue resistance and compression set. The single-part cost is 23% less than the previous two-part assembly, while delivery time has been shortened, and part quality and repeatability enhanced because of the one-piece design.

Metal-on-metal highpressure waterjet seal cuts maintenance costs

Jet Edge’s high-pressure fluid sealing mechanism improves waterjet seal life and lowers maintenance costs by providing robust metal-on-metal sealing without the use of plastic seals. This technology uses two convex curved surfaces in single-line contact with one another to seal ultra-high-pressure fluid at static pressures up to 130,000 psi. The company initially developed the seal to meet the increased performance demands of its XStream (XP) pressure intensifier pumps,

Rubber seal is metal-detectable and X-ray inspectable

As elastomers degrade, there is a high risk of rubber fragments breaking off, resulting in product contamination, product recall, lost product and downtime. Due to its low conductivity, elastomeric material is often missed by even the strongest detection systems. Daemar’s detectable seals are made from a standard elastomer, such as Buna, Sili-

cone, FKM Fluoroelastomer and EPDM, with the addition of a metal-impregnated compound, allowing displaced rubber material (fragments as small as 1 mm) to be located by an in-line metal detector. This enables systems to instantly reject contaminated product. X-ray inspectable and metal-detectable seals provide confidence to food, dairy and pharmaceutical manufacturers by ensuring product safety and integrity.

SKF’s sealed energy-efficient, deep-groove ball bearing (sealed E2 DGBB) is suitable for applications in many industries, ranging from electric motors and twowheelers to industrial conveyors and water pumps.

The sealed E2 DGBB reduces friction by more than 30% compared to the SKF Explorer sealed DGBB. As a result, it significantly saves energy and reduces CO2.

The addition of a seal provides minimal interference between the inner ring and seal lip without compromising the performance of the sealing ability. For a typical textile machine running 8,000 hours per year equipped with 200 sealed E2 DGBBs, the energy reduction is estimated at 11,310 kWh annually. This reduction translates into a CO2 saving of 8.5 tonnes per year, according to a world power grid mix CO2 factor of 0.749 kg CO2 e/kWh. Available in sizes up to 52 mm outer diameter, the item is included in the company’s BeyondZero portfolio of products that offer enhanced environmental performance characteristics.

Makita’s cordless 18V LXT Multi Tool is designed for up to 15 minutes of run time using its fast-charging 18-volt LXT lithium-ion battery. Variable speed (6,000-20,000 opm) and a soft-start feature are meant to give the user more control for each application.

The tool is a little bulky and has some weight to it at 1.4 kg, but this only made my project easier by letting it do its job without having to push it to its limits.

The tool uses a 3.2-degree oscillation angle for faster, more aggressive cutting and sanding.

It can be purchased by itself or with batteries and a charger, as well as in various combo kits.

the norm. NTN tapered roller bearings are made to meet or exceed industry standards and feature case carburized steel.

Optimized roller/rib interface promotes lubrication and lowers bearing running torque.

Honed raceways ensure low friction for trouble free operation.

Carburizing hardens the steel from the surface to the proper depth, leaving a relatively soft core, improved durability and longer life. These results make the material ideal for shock loading and extreme conditions.

Schaeffler Introduces a Genuine Breakthrough in Condition Monitoring: WiProM with FisNet is the industry’s first truly cost-effective diagnostic tool for analyzing the performance of vital plant equipment such as motors, pumps and generators. WiProM’s portable design allows for quick and easy deployment, while the proprietary FisNet wireless network transmits the data to a monitoring center (yours or ours) for analysis.

Real Solutions - Real Savings When a customer faced the daunting task of performing end-of-warranty inspections on scores of gearboxes and generators, Schaeffler was called upon for a solution. A permanent online monitoring system was deemed cost-prohibitive, and the facility was not staffed with highly trained data analysis experts.

Armed with a single yellow carrying case containing a WiProM diagnostic unit, Schaeffler experts set about the task of analyzing factors such as meshing of gears and generator performance. Within three weeks, Schaeffler was able to provide condition monitoring data that has, so far, saved the customer over $1 million.
