2-Inch Two-Piece Aluminum Clamp Collar

The Ruland Manufacturing SP-32-A is a 2-piece clamp shaft collar machined from 2024 aluminium. It fits a 2 in round bore and uses alloy steel screws to secure components on inch-dimension shafts. Maintenance teams and machine builders use it for positioning, spacing or limiting travel without marring the shaft surface.

Replaces Solid Collars When Shaft Removal Is

A two-piece design lets you install or reposition the collar without sliding it over the shaft end or disassembling adjacent hardware. The jump is worth it when downtime for shaft removal exceeds the few seconds needed to open the clamp, or when the shaft carries bearings, gears or other fixed elements that cannot be removed.

Verify Bore Diameter and Clearance Before Ordering

Confirm the shaft measures exactly 2 in and that the 3.27 in clearance diameter clears nearby brackets, guards or bearing housings. Ensure the 11/16 in collar width fits the available axial space and that aluminium’s strength and corrosion profile suit the operating environment.

Questions about this item

What shaft diameter does the 2 in bore of the SP-32-A clamp collar fit?

The collar has a 2 in round bore designed to clamp onto a 2 in diameter shaft.

How do you install the two-piece clamp collar and which step is often missed?

Separate the two halves, place them around the shaft, insert both alloy-steel screws, and tighten them alternately to evenly distribute the clamping force.

When should the alloy-steel screws on this aluminum collar be replaced?

Replace the screws if the threads are stripped, the heads are rounded, or corrosion prevents proper torque during re-installation.
