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.

Weldable Two-Piece Shaft Collars
Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Because they’re grade 1018 carbon steel, you can easily weld them to other components. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.

Weldable Shaft Collars
To install, slide these one-piece collars onto the end of your shaft. Because they’re grade 1018 carbon steel, you can easily weld them to other components. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screw to secure.
