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.

Linear Ball Bearings for Support Rail Shafts
Mount these bearings on a support rail shaft for applications requiring maximum rigidity. All have end seals to keep lubricant in and dirt out. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).
Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.
Fixed-alignment bearings are for use where shaft misalignment is unlinkely.

High-Load Linear Ball Bearings for Support Rail Shafts
Designed for heavy loads, these bearings have higher load capacities than comparable standard linear ball bearings for support rails. Use them for applications that require maximum rigidity. All are self-aligning to compensate for shaft misalignment. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).

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.
