Shaft Collar CL-22-SS 303 Stainless

This Ruland CL-22-SS shaft collar is a 1-piece clamp component made from 303 stainless steel. It fits a round bore of 1-3/8 inch with an outside diameter of 2 1/4 inch and a collar width of 9/16 inch. The clearance diameter measures 2.47 inches for assembly planning.

Upgrade from set-screw collars

A clamp collar replaces set-screw types when shaft damage must be avoided and holding power needs to be uniform. The jump is worth it for applications with frequent adjustment or where marring the shaft surface is unacceptable. Stainless steel construction adds corrosion resistance for harsh environments.

Capacity for light-duty positioning

The 303 stainless material comfortably handles light-duty positioning, spacing and component retention on 1-3/8 inch shafts. It runs out when high axial loads or torque transmission exceed the clamp screw capacity. Not suited for keyed shafts or applications requiring a keyway.
