Two-Piece Shaft Collars


For Round Shafts	For Keyed Shafts

Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.

Carbon Steel—Strong and easy to machine. Use in dry environments, since moisture will cause steel to rust.

Slide these collars from one end of your shaft and tighten the clamping screw. They grip firmly and evenly without marring the shaft, so you can reposition or remove them later.
