Shaft Collar for Inch Shafts

This Climax Metal Products C-137-BO shaft collar fits round shafts with a 1 3/8 inch bore diameter. The one-piece carbon steel construction uses a set screw to lock onto the shaft. It is sold as a single piece for maintenance or replacement tasks.

Bore Diameter Determines Fit

The collar accepts a round shaft measuring exactly 1 3/8 inches across the bore. Its outside diameter is 2 1/8 inches with a 3/4 inch width and a 2.13 inch clearance diameter. Grade 1211 carbon steel forms both the collar and the set screw.

Simple Set Screw Installation

Sliding the collar onto the shaft and tightening the carbon steel set screw secures it in place. The one-piece design requires no extra tools or disassembly. Over-tightening the screw can mar the shaft surface or strip the threads, so apply firm but measured force.

Questions about this item

How does the 1-3/8 in bore size translate when the collar is installed on a shaft?

The 1-3/8 in bore fits a matching inch-series shaft directly; the 2 1/8 in outside diameter and 3/4 in width then sit flush against the shaft shoulder to locate or retain components.

What does the set-screw fastening method limit in practice?

A single carbon-steel set screw clamps the 1-piece carbon-steel collar onto the shaft, so holding power depends on screw torque and shaft hardness rather than a clamping-screw array.

What clearance and mounting space does the 2.13 in clearance diameter require?

The 2.13 in clearance diameter means adjacent parts must stay clear of that circle, while the 3/4 in collar width determines the axial space the collar occupies on the shaft.
