Precision Shaft Collar for 3/4 Inch Bore

The Ruland CL-12-A is a one-piece clamp collar machined from 2024-grade aluminum with a 3/4 inch round bore. It suits hobbyists, restorers or collectors who need a lightweight, corrosion-resistant fastening point on inch-sized shafts. The clear anodised finish keeps the metal visible for inspection or display purposes.

Simple One-Piece Clamp Installation

A single alloy-steel socket screw tightens the split clamp evenly around the shaft without marring the surface. No keyway or set-screw drilling is required, so alignment stays repeatable. Over-torquing the screw can distort the thin aluminum wall, and the 1/2 inch collar width leaves little leverage for very high axial loads.

Verify Shaft Diameter and Clearance First

Measure the shaft to confirm an exact 3/4 inch outside diameter before ordering. The collar’s 1 1/2 inch outside diameter and 1.81 inch clearance diameter determine the space needed inside brackets or housings. California Proposition 65 warnings apply, so handlers should follow safe-practice guidelines for the listed chemicals.

Questions about this item

How do I verify the CL-12-A shaft collar is seated correctly after installation?

The 1-piece clamp design tightens with its alloy steel screw; a secure fit is confirmed when the collar does not rotate or slide on the 3/4 in shaft.

What components are included with the CL-12-A shaft collar?

The package contains one 2024 aluminum collar with a 1 1/2 in outside diameter, 1/2 in width, 1.81 in clearance diameter, and an alloy steel clamping screw.

Which bore size should I select for a 3/4 inch round shaft?

Choose the CL-12-A model with its 3/4 in round bore diameter; it matches the shaft exactly and uses a 1-piece clamp construction.
