Precision 2-Piece Shaft Collar

The Ruland Manufacturing SP-11-F is a two-piece clamp collar machined from black-oxide 1215 lead-free steel. It fits an 11/16 in bore and secures components on inch-sized shafts in machinery and automation assemblies. The split design allows installation or repositioning without sliding the collar over the shaft end. RoHS2 and REACH compliant.

11/16 Inch Bore Fit

The single specification that decides compatibility is the plain bore diameter of 11/16 in. The collar accepts only shafts matching this exact inch dimension; metric or larger inch shafts will not seat correctly. A #10-32 alloy-steel screw provides the clamping force, and the 1.562 in clearance diameter ensures the screw head clears adjacent parts.

Clamping Range and Temperature Headroom

The 7/16 in width distributes holding force across the shaft while the black-oxide finish resists corrosion in standard industrial environments. Operating temperature spans -40 to 350 degrees F, so the collar remains reliable in cold-start and high-heat zones. It is not suited for applications requiring a larger bore, a one-piece solid collar, or shaft diameters beyond the stated 11/16 in.

Questions about this item

How much shaft diameter does the 11/16 in bore actually grip?

The 11/16 in plain bore clamps directly onto a shaft of that exact diameter when the two-piece collar is tightened.

What does the #10-32 screw size mean for holding power?

The #10-32 alloy-steel socket screw provides the clamping force; torque it to the manufacturer's specification for a secure hold.

Will the 1 3/8 in outside diameter clear my adjacent components?

The collar's outside diameter is 1 3/8 in with a 1.562 in clearance diameter, so allow at least that much radial space.
