Two-Piece Clamping Collar
The Ruland Manufacturing SP-47-F is a two-piece shaft collar made from 1215 carbon steel with alloy-steel screws. It clamps onto a round shaft with a 2-15/16 in bore and presents a 4-1/4 in outside diameter. The split design allows installation or adjustment without removing other components from the shaft.
Replaces Set-Screw Collars
This collar replaces traditional set-screw types that can mar the shaft and loosen under vibration. The clamping action distributes holding force evenly around the circumference, making the upgrade worthwhile when shaft damage must be avoided or when frequent repositioning is required. The 7/8 in width provides a broad contact surface for secure grip.
Check Shaft Diameter And Clearance
Verify that the shaft measures exactly 2-15/16 in so the bore matches without play. Confirm that the 4.5 in clearance diameter fits inside adjacent guards, bearings or frame members. Ensure the 7/8 in collar width does not interfere with nearby components along the shaft axis.

Questions about this item
Will the 4.5 in clearance diameter let this collar clear my existing shaft hardware?
The 4.5 in clearance diameter provides space around the shaft for adjacent components; verify your hardware fits within that envelope.
What is the correct torque sequence for the alloy steel screws on this 2-piece collar?
Tighten each screw alternately in small increments to seat the clamp evenly; final torque should follow the alloy steel screw grade recommendation.
How often should I inspect the carbon steel 1215 collar for wear or corrosion?
Inspect at each scheduled machine shutdown; carbon steel 1215 can rust in damp environments, so re-lubricate or replace if surface pitting appears.
