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.

Precision Adjustable-Width Clamping Shaft Collars
Two knurled sides provide micrometer-like movement for precise width adjustments. Use them to set the stroke length of a linear sliding guide rod or shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide the collar onto your shaft and tighten the clamping screws on one side to secure. Then rotate the other side to make width adjustments. Finally, tighten the clamping screws to lock the collar in place. Collars are black-oxide steel, which offers some corrosion resistance.
