Shaft Collar 1-1/16 Inch Bore

This two-piece clamp collar fits a round shaft measuring 1-1/16 inches and is made from carbon steel grade 1215 with a black oxide finish. The split design allows installation or adjustment without removing other components from the shaft.

Two-Piece Clamp With Alloy Steel Screw

The collar width is 1/2 inch and the outside diameter is 1 7/8 inches, giving a clearance diameter of 2.14 inches. A single alloy steel screw secures both halves, distributing clamping force evenly around the shaft without marring the surface.

Inch-Series Collar For General Power Transmission

The collar uses inch-series dimensions and has no keyway or threaded bore, so it suits applications that rely solely on friction grip. California Proposition 65 warnings apply because the steel contains a listed chemical.
