2-Piece Aluminum Shaft Collar

The Ruland Manufacturing SP-10-A is a two-piece clamp-style shaft collar machined from 2024 aluminum alloy. It fits a 5/8 in round bore and uses alloy steel screws to secure the collar without marring the shaft. This design allows installation or adjustment without removing other components from the shaft.

Suits inch shafts needing frequent adjustment

This collar suits maintenance teams and machine builders working with inch-dimension shafts who need a strong, reusable clamp that can be repositioned quickly. It is not suited for metric shafts, for applications requiring a keyway to transmit torque, or for environments where aluminum contact is prohibited.

Check shaft diameter and clearance before ordering

Verify the shaft measures exactly 5/8 in diameter so the clamp can achieve full holding power. Confirm the 1.5 in clearance diameter clears adjacent bearings, brackets or guards. Ensure the 7/16 in collar width fits the available axial space on the shaft.

Questions about this item

What shaft diameter is required for the 5/8 in bore?

The collar fits a 5/8 in round shaft; the bore diameter is 5/8 in and the bore type is round.

Will the 1 5/16 in outside diameter clear existing components on a 5/8 in shaft?

The collar outside diameter is 1 5/16 in and the clearance diameter is 1.5 in, so adjacent parts must allow at least 1.5 in of radial space.

How can I confirm the clamp is holding correctly after installation?

Tighten the alloy-steel screws until the two-piece collar seats firmly on the shaft with no axial play; the 2024 aluminum body should show no deformation.
