3/4-inch bore shaft collar

The Ruland Manufacturing QCL-12-A is a single-piece aluminium shaft collar with a 3/4-inch round bore. It suits maintenance engineers and machine builders who need a quick-clamp fastening method on inch-sized shafts without marring the surface.

Black anodised 6061 aluminium finish

The collar is made from 6061-grade aluminium with a black anodised coating. This surface treatment adds corrosion resistance and reduces galling when the collar is repositioned. A stainless-steel screw with a bright finish provides the clamping force.

Simple one-piece installation

The one-piece construction slides onto the shaft and locks with a single screw, so no disassembly of adjacent components is required. Over-tightening the screw can deform the aluminium bore, and the anodised coating may wear if the collar is moved frequently along a rough shaft.

Questions about this item

Will the stainless-steel clamping screw need periodic tightening or replacement?

The collar uses a stainless-steel screw that resists corrosion; retighten only if vibration loosens it.

What is the first limitation when the collar runs continuously under load?

The 6061 aluminium body reaches its yield strength before the clamp slips, so torque capacity is the limiting factor.

Does the black anodised finish affect heat build-up or noise during all-day operation?

The anodised surface does not change thermal behaviour; the collar runs silently and adds negligible heat.
