Two-piece shaft collar for 1-1/16 in shafts

The Ruland Manufacturing SP-17-A is a 2-piece clamp-style collar machined from 2024 aluminium. It fits round bores of 1-1/16 in and uses alloy-steel screws to secure components on inch-system shafts in power-transmission assemblies.

Capacity and headroom

The collar provides a 1 7/8 in outside diameter and a 2.14 in clearance diameter with a 1/2 in width, giving adequate clamping surface for moderate radial and axial loads. It is not suited for applications that demand higher torque capacity or wider bearing surfaces than these dimensions allow.

Bundled accessories and software

No accessories, software or additional hardware are included with the collar. The package contains only the two-piece aluminium collar and its alloy-steel mounting screws, so installers must supply any required tools, lubricants or shaft-key components separately.

Questions about this item

Will the 1-1/16 in bore fit the 1-1/16 in shaft I already use?

Yes, the bore diameter is 1 1/16 in and the bore type is round, matching a shaft of that size.

How can I confirm the collar is clamping correctly after installation?

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

Does the package include the alloy steel screw or must I source it separately?

The collar construction is 2-piece with an alloy steel screw included, so no separate hardware is required.
