Case Studies


Handi Quilter’s dedicated engineering team encountered quite a few technical challenges when designing their large capacity HQ24 Fusion machine. The long-arm quilting machine applies an intermittent but significant radial load as the needle pierces the quilt material up to 2,200 times a minute...

Commercial lawn mowers take a lot of abuse as they ride over sticks, rocks and stumps. For this reason, the bearings that raise and lower the mower deck must withstand multiple high shock loads and be extremely durable...

When designing the equipment’s print image mechanism, the company’s engineers needed a bearing that could deliver precision performance, cover a small footprint and handle a high load with no wear over many millions of print cycles...

The Checksum engineers’ challenge was to find bearings that would operate in an oscillatory motion and carry a peak load of 2,700 pounds, with a minimum bearing life of 500,000 cycles. Corrosion resistance, maintenance-free life, low cost and ease of installation were also important...

The Parata Robotic Dispensing System is the most productive and accurate pharmaceutical dispensing system in the world. In fact, it dispenses medications with 100% accuracy at the rate of 150+ transactions an hour. Fast and compact, this high-capacity machine demanded economical bearings with a tiny footprint...

Wheelchair lifts on buses and trains must be able to raise and lower heavy loads at relatively slow speeds with utmost reliability and stability. Moreover, because they slosh through rain, ice, snow, salt and deicing chemicals, all of the lifts’ components must be able to withstand the most difficult conditions...

Nita is a Quebec-based manufacturer of high-quality transport and manipulation systems for large, rectangular lithographic printing plates. The plates are made of extremely soft aluminum and must be handled with care and precision as they are delivered, rotated, notched and fed into the printing press...

The original bearing design required welding big blocks of stainless steel onto the chassis, which caused unsightly distortions and pockets. Despite their best efforts to correct the warping, the results still looked unprofessional...

The solar curtains were on a timer, shading the atrium from the desert sun as the day progressed. Unfortunately, every time they moved, the solar curtains produced a loud squeal, which echoed off the hard surfaces of the atrium, annoying guests and employees alike. The problem? A simple plastic bearing...

Vulcan engineers were faced with a number of challenges. For example, the hinged door on the oven required a bearing that would withstand the rigors of a busy commercial kitchen, including acidic food spills, corrosive cleaning materials, and 500°F ambient heat when the door was open. And did you know that chefs often stand on open oven doors to reach upper shelves and griddles?...

Aluminum Ladder’s most recent challenge involved gangways used for unloading barges and ships on the Great Lakes, where brackish water was corroding the existing bearings and cracking the cast housings. When the gangways didn’t work, the ships couldn’t be unloaded. The repair costs and downtime were untenable...

The world’s most popular small arms training unit — Meggitt Training Systems’ Stationary Infantry Target (SIT) — was failing in bad weather. The company’s Stationary Armor Target (SAT) battle target system had the same problem. Water leaks short-circuited the electrical system, and the expensive devices were rendered useless...

Engineers suggested a sheet metal chassis to lower costs — a big plus. But the downside of using sheet metal was that the chassis had to be constructed in two pieces, increasing the likelihood of misalignment. Bottom line? The new design required a different bearing to ensure smooth, quiet and efficient operation...

The bearings in their existing gangplanks failed regularly due to wear, and the huge expense and downtime to replace 20 of them at a time was unacceptable...

These machines require maintenance-free bearings that can withstand high usage in a variety of extreme conditions, from salty, wet beach locations to freezing mountain towns...

The compactor demands a compact, low-maintenance bearing able to handle a high load (1,200 pounds) in any type of weather over a 10-year life span...
