Precision Two-Piece Shaft Collar

The Ruland SP-33-F is a 2-piece clamp-style shaft collar machined from carbon steel grade 1215. It fits a round bore of 2-1/16 in and provides a secure, mar-free hold on shafts in power transmission assemblies. Maintenance teams and machine builders use it for quick positioning without disassembly.

Replaces Solid Collars on Installed Shafts

The split 2-piece design allows installation or adjustment without removing bearings, gears or other components already mounted on the shaft. This makes the jump worthwhile whenever downtime for shaft removal is impractical or when frequent repositioning is required during setup and alignment.

Handles 2-1/16 in Shafts with 3.36 in Clearance

The collar width is 3/4 in and the outside diameter measures 3 1/8 in, giving a clearance diameter of 3.36 in for adjacent hardware. Alloy steel screws provide clamping force on carbon steel grade 1215. The design is not suited for applications requiring a keyway or threaded bore.

Questions about this item

What shaft diameter does the 2-1/16 in bore fit?
