Shaft Collar 2-9/16 in Bore
This two-piece clamp collar fits a 2-9/16 inch round shaft and is machined from 1215 carbon steel. The split design allows installation or adjustment without sliding the collar over the shaft end. Alloy steel screws provide the clamping force.
Verify Shaft Diameter and Clearance
Confirm the shaft measures exactly 2-9/16 inches and has a round bore before ordering. Ensure at least 4.15 inches of radial clearance is available so the 3-7/8 inch outside diameter collar can rotate or be positioned without interference. Check that the 7/8 inch width suits the axial space on the shaft.
Steel Construction Handles Standard Loads
Carbon steel material and alloy steel screws deliver reliable holding power for typical power transmission applications. The two-piece construction distributes clamping pressure evenly around the shaft without marring the surface. No special cooling or lubrication is required for normal operation.

Questions about this item
Does the two-piece collar arrive assembled, or do I need to supply my own fasteners?
The SP-41-F is a 2-piece clamp collar made from 1215 carbon steel with an alloy-steel screw included; no extra hardware is required for installation.
When would I choose the 2-9/16 in bore version over a smaller or larger bore?
Select this 2-9/16 in bore when the shaft measures exactly that diameter; the collar’s 3 7/8 in outside diameter and 4.15 in clearance diameter then provide the correct fit and wrench access.
What does the 4.15 in clearance diameter mean once the collar is clamped on a shaft?
It is the maximum diameter the collar sweeps when tightened, so adjacent components must stay outside a 4.15 in circle to avoid interference.
