About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Mounted Linear Ball Bearings for Support Rail Shafts
Mount these bearings on a support rail shaft for applications requiring maximum rigidity. End seals keep lubricant in and dirt out. Self-aligning bearings compensate for shaft misalignment.

High-Load High-Speed Mounted Linear Sleeve Bearings for Support Rail Shafts
With two bearings mounted in a single housing, these bearings have higher load capacities than standard ones. A ceramic liner helps them achieve high speeds as well as rapid acceleration and deceleration. Mount these bearings on a support rail shaft for applications requiring maximum rigidity. Made of ceramic-coated aluminum, their housing is lightweight and corrosion resistant. These bearings are for fixed alignment, ideal for well-aligned shafts. Note: Not for use with ceramic-coated aluminum or 300 series stainless steel shafts.

High-Load Mounted Linear Sleeve Bearings for Support Rail Shafts
With two bearings mounted in one housing, these sleeve bearings are designed to withstand heavy loads. Use them on round support rail shafts for applications that require maximum rigidity. All of these bearings have a ceramic-coated aluminum housing that’s lightweight and stands up to corrosion. They also have a slippery, chemical-resistant PTFE liner, so there’s no need for lubrication. These fixed-alignment bearings are for use where shaft misalignment is unlikely.

Bearing Retaining Locknuts
With a nylon insert that grips your threaded shaft or spindle without damaging its threads, these locknuts—also called shaft nuts—hold bearings, bushings, gears, and pulleys prone to vibration tightly in place. They come as one piece, so you can easily clamp them onto your shaft or spindle. But, since they aren’t made entirely of metal, they don’t stand up to heat as well as all-metal locknuts. Slots in their sides mean you can tighten and loosen them with a spanner wrench or spanner socket. Their face is also chamfered to help keep the size and weight of your assembly at a minimum. All meet international standards for bearing locknut dimensions.
When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.
All carbon steel locknuts are strong and resist wear, though they don’t stand up to corrosion as well as stainless steel locknuts. Zinc-plated steel locknuts resist rusting from some moisture, but you shouldn’t use them with salt water or chemicals.
303 stainless steel locknuts resist corrosion better than steel locknuts but aren’t as strong. They withstand washdowns and chemicals.
