  • 303 stainless steel resists corrosion in harsh environments

Precision Shaft Collar

The Ruland Manufacturing CL-20-SS is a one-piece clamp collar machined from 303 stainless steel. It fits a 1-1/4 inch round bore and uses a stainless steel screw for secure axial positioning on shafts.

Build Integration

The collar measures 2 1/16 inches outside diameter with a 2.3 inch clearance diameter and a 1/2 inch width. Its clamp design locks without marring the shaft, freeing the keyway for other components.

Target Users

Suited for maintenance teams and OEMs needing corrosion-resistant holding power in inch-series drives. Not for buyers who require a keyway slot, a two-piece split design, or metric bore dimensions.

Questions about this item

What is the maximum outside diameter the 1-1/4 in bore collar reaches when clamped?

The collar outside diameter is 2 1/16 in and the clearance diameter is 2.3 in, giving the total radial envelope under clamp load.

Does the 303 stainless steel clamp collar generate heat or noise during continuous shaft rotation?

The 1-piece clamp collar has no moving parts, so it produces no audible noise and adds negligible frictional heat to the shaft.

Which fastener is required to secure the CL-20-SS to a 1-1/4 in shaft?

The collar includes a stainless steel socket-head cap screw; a matching hex key is the only tool needed for installation.
