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.

Machinable-Bore Clamping Two-Piece Shaft Collars

Customize the bore of these collars to precisely fit your shaft. The two-piece design allows you to install them anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.
Add a plating or coating of your choice to unfinished steel collars. Black-oxide steel collars have some corrosion resistance. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Machinable-Face Shaft Collars

These collars have two different sides—one locks down like a standard clamping shaft collar; the other has a flush face that you can machine to add slots, holes, and grooves to match your special setups. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screws to secure. Collars are black-oxide steel, which offers some corrosion resistance.
