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.

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).
Bearings with end seals keep lubricants in and dirt out.
Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Bearing Retaining Nuts
Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle. They have slotted sides, so you can tighten and loosen them with a spanner wrench or spanner socket.
Chamfered-face retaining nuts weigh less and produce less heat than stepped-face nuts.
Carbon steel retaining nuts are strong and resist wear.
303 stainless steel retaining nuts resist corrosion better than steel. They also withstand washdowns and chemicals.
