Ruland SP-48-SS 2-Piece Clamp Collar

The Ruland SP-48-SS is a 2-piece clamp-style shaft collar manufactured from 303 stainless steel. It fits a 3-inch round bore and provides a secure hold on shafts without marring the surface. This component suits maintenance, repair and OEM assembly work where reliable axial positioning is required.

303 Stainless Steel and Two-Piece Design

The 303 stainless steel construction resists corrosion in wash-down, food-processing and outdoor environments. The two-piece clamp configuration allows installation or removal without sliding the collar over the shaft end, reducing downtime during adjustments. Stainless steel screws are included for consistent material compatibility.

Suits Inch-Series Shafts Needing Non-Marring Grip

This collar serves technicians and engineers working with 3-inch inch-series shafts who need a reusable, non-marring clamping solution. It is not intended for applications requiring a keyway or threaded bore. Buyers who need a one-piece solid collar or a different bore diameter should select an alternative model.

Questions about this item

Will the 303 stainless-steel screws need periodic replacement?

The 303 stainless-steel screws resist corrosion; replace only if threads strip or heads round off during adjustment.

What stops the collar from holding under continuous load?

The 4.5 in clearance diameter limits shaft engagement; excessive torque can overcome the two-piece clamp grip.

Does the 303 stainless collar generate heat or noise during all-day operation?

No moving parts means no heat build-up or noise; the static clamp remains silent and at ambient temperature.
