Climax Metal Products 1C-125-S One-Piece Clamping Collar collectible

One-Piece Stainless Clamping Collar

This one-piece clamping collar from Climax Metal Products is machined from 303 stainless steel for corrosion resistance and clean appearance. It fits a 1 1/4 inch round bore and uses a single socket-head screw to lock onto shafting without marring the surface. The unit is supplied new and intended for maintenance, repair or light-duty power-transmission builds.

Bore and Width Define Fit

The 1/2 inch collar width and 2.31 inch clearance diameter determine how much axial space the clamp occupies and whether adjacent components can clear it. Because the bore is plain round with no keyway, the collar relies solely on friction from the stainless screw for holding power. No additional hardware or shims are included in the package.

Inch-Series Limits

The collar follows inch-series dimensions, so it will not mate with metric shafting without an adapter or custom machining. The 303 stainless material offers good machinability but lower tensile strength than heat-treated alloy steels, limiting torque transmission in high-load drives. Buyers who need a split two-piece design for in-place installation or a larger bore size must select a different part.
