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.

Corrosion-Resistant Mounted Linear Ball Bearings for Support Rail Shafts

Outdoor as well as mild chemical environments are no problem for these bearings. They have stainless steel balls for corrosion resistance. Mount them on a support rail shaft for applications requiring maximum rigidity. They are self-aligning to compensate for shaft misalignment.

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. 303 stainless steel locknuts resist corrosion better than steel locknuts but aren’t as strong. They withstand washdowns and chemicals.
