The Ruland Manufacturing SP-4-SS is a two-piece clamp-style shaft collar machined from 303 stainless steel. It fits a 1/4-inch round bore and has a 5/8-inch outside diameter with a 9/32-inch width. The collar uses a stainless steel screw for secure fastening on shafts.

Questions about this item

Will the 2-piece 303 stainless collar fit onto a 1/4 inch shaft already on my machine?

The bore diameter is 1/4 in and the collar construction is 2-piece, so it clamps around an existing 1/4 in shaft without disassembly.

How can I verify the clamp is secure after installation?

Tighten the stainless steel screw until the two halves meet evenly; the 5/8 in outside diameter and 0.77 in clearance diameter should then be concentric with the shaft.

Does the package include the mounting screw or must I supply it?

The screw material is stainless steel and is part of the collar assembly; no separate hardware is required.
