Ruland SP-25-F 2-Piece Shaft Collar
The Ruland SP-25-F is a two-piece clamp-style shaft collar manufactured from 1215 carbon steel with a black oxide finish. It is designed for positioning and securing components on a 1-9/16 inch round shaft in power transmission applications. The split construction allows installation or adjustment without removing other mounted hardware, reducing downtime during maintenance or alignment tasks.
Suited for inch-based shafting
This collar suits engineers and maintenance technicians who require a secure, reusable clamp on inch-dimension shafts without keyway features. It is not intended for applications demanding a keyed connection, metric bore sizes, or single-piece solid collar designs. Buyers needing integrated keyways, different bore diameters, or alternative materials should evaluate other collar types.
1-9/16 inch bore with 2.58 inch clearance diameter
The collar accommodates a 1-9/16 inch round bore and provides a 2.58 inch clearance diameter for assembly access. Its 9/16 inch width and alloy steel screws deliver reliable holding power for moderate axial loads. The 1215 lead-free steel grade offers good machinability and consistent clamping performance, though extreme vibration or shock loads may require additional locking methods.

Questions about this item
What shaft diameter must I already have for the 1-9/16 in bore to fit?
The collar clamps onto a round shaft measuring exactly 1-9/16 in.
Will the 2.58 in clearance diameter clear the 2-3/8 in outside diameter of an adjacent collar on the same shaft?
Yes, the 2.58 in clearance provides additional radial space beyond the 2-3/8 in OD.
How can I confirm the black oxide finish on the 1215 carbon steel is intact after installation?
Inspect the collar surface for a uniform dark coating without bare metal showing at the split or screw holes.
