1-1/2 Inch Aluminum Shaft Collar

The Ruland Manufacturing CL-24-A is a one-piece clamp-style shaft collar machined from 2024 aluminium alloy. It fits a round bore of 1-1/2 inches and uses an alloy-steel screw to lock onto a shaft without marring the surface. The collar suits power-transmission assemblies that need quick positioning or component retention.

Suited for light-duty clamping on inch-size shafts

This collar works well for hobbyist machinery, prototype fixtures and low-torque drives where aluminium’s weight saving matters. It is not intended for high-vibration shock loads, applications that demand a two-piece split design for in-place installation, or environments where the Proposition 65 listed chemicals are prohibited.

2024 aluminium construction with 9/16 inch width

The material provides adequate clamping force for moderate radial loads while keeping rotating mass low. At 2.58 inches clearance diameter the collar clears most adjacent hardware, yet the single-piece design limits use where shafts cannot be slid through from an end. For heavier axial forces a steel or two-piece alternative should be considered.

Questions about this item

What shaft diameter must I already have for the CL-24-A collar to fit?

The collar accepts a 1-1/2 in round bore, so your shaft must measure exactly that diameter.

Will the 2-3/8 in outside diameter clear the adjacent bearing housing on my current assembly?

The collar's outside diameter is 2-3/8 in with a 2.58 in clearance diameter; verify that your housing provides at least that much space.

How can I confirm the clamp screw is holding the collar securely after installation?

Tighten the alloy-steel screw until the 1-piece aluminum collar grips the shaft firmly with no axial movement.
