Metric clamp collar for 30 mm shafts

The Ruland Manufacturing MSP-30-SS is a 2-piece clamp shaft collar machined from 303 stainless steel. It fits a 30 mm round bore and uses a split design that tightens around the shaft without marring the surface.

Suits metric drive lines needing removable collars

This collar serves maintenance teams and OEM builders who must install or reposition the collar without sliding it over shaft ends. It is not for applications that require a keyway, a threaded bore, or a solid one-piece collar.

30 mm bore and 54 mm outside diameter

The 30 mm round bore matches the shaft, while the 54 mm outside diameter and 15 mm width define the space the collar occupies. The 303 stainless construction resists corrosion in wash-down or outdoor environments.

Questions about this item

Will the 54 mm outside diameter and 59.2 mm clearance diameter fit inside my housing?

The collar has a 54 mm outside diameter and a 59.2 mm clearance diameter; verify your housing bore exceeds 59.2 mm for the two-piece clamp to swing open and seat properly.

What screw size and torque should I use when installing this 2-piece clamp collar?

Both clamp screws are stainless steel; tighten them evenly in an alternating pattern to the manufacturer's recommended torque for 303 stainless hardware to avoid distorting the 15 mm wide collar.

Does the 303 stainless steel collar need lubrication or scheduled replacement in a wash-down environment?

303 stainless steel resists corrosion in wash-down settings; no routine lubrication is required, but inspect the clamp screws and bore periodically for fretting or galling and replace if clamping force drops.
