Two-piece stainless steel clamping collar

The Climax Metal Products 2C-125-S is a 2-piece clamping collar machined from 303 stainless steel with a carbon-steel screw. It fits a 1 1/4 in round bore and suits machinery builders who need quick shaft positioning without marring the shaft surface.

Replaces solid one-piece collars

A split 2-piece design lets you install or reposition the collar without sliding it over shaft ends or removing mounted components. The upgrade is worth it when downtime for disassembly is costly or when the shaft carries bearings, gears or pulleys that cannot be removed easily.

Verify shaft diameter and clearance

Confirm the shaft measures exactly 1 1/4 in and that the 2.31 in clearance diameter clears adjacent parts. Ensure the 1/2 in collar width fits the available axial space and that carbon-steel screw material is compatible with the operating environment.

Questions about this item

What shaft diameter does the 1 1/4 in bore of this two-piece clamping collar fit?

The collar fits a 1 1/4 in round shaft; its bore diameter matches that size exactly.

How do the carbon-steel screws secure the 303 stainless-steel collar halves during installation?

Tighten the socket-head cap screws evenly in a cross pattern to draw both halves together without distorting the 2 1/16 in outside diameter.

When should the carbon-steel screws be replaced on this 303 stainless-steel clamping collar?

Replace the screws if the threads strip, the heads round off, or corrosion appears on the carbon-steel hardware.
