Shaft Collar 1-1/4 in Aluminium

The Ruland CL-20-A is a one-piece clamp-style shaft collar with a 1-1/4 in plain bore machined from 2024 aluminium. It suits light-duty positioning and spacing tasks on inch-series shafts in machinery and automation builds.

Simple Clamp Installation

A single 1/4 in.-28 alloy-steel socket screw secures the collar without marring the shaft. The screw threads into the aluminium body, so over-tightening can strip the threads; use a calibrated driver and stop at the recommended torque.

Capacity and Headroom

The collar provides 2.295 in outside clearance and 1/2 in width for moderate axial loads within a -40 to 225 °F operating range. It is not intended for high-torque transmission or heavy shock loading where a two-piece or steel collar would be required.

Highlights

  • Secure one-piece clamp grip on 1-1/4 in shafts

  • Alloy-steel 1/4-28 screw delivers reliable holding force

Questions about this item

How can I verify the collar is clamping correctly on a 1-1/4 in shaft after installation?

The bore diameter is 1 1/4 in and the clearance diameter is 2.295 in; tighten the 1/4 in.-28 alloy-steel screw until the collar grips the shaft firmly without damaging the 2024 aluminium body.

What comes in the package and is any extra hardware needed?

The box contains one clamp-style shaft collar; the required 1/4 in.-28 alloy-steel screw is already fitted, so no separate fasteners are necessary.

Should I choose the aluminium version or a different material for high-temperature use?

This 2024 aluminium collar is rated from -40 °F to 225 °F; if your application exceeds 225 °F, select a steel or stainless-steel collar instead.
