30 mm Stainless Steel Clamp Collar

The Ruland Manufacturing MCL-30-SS is a one-piece clamp-style shaft collar machined from 303 stainless steel. It fits a 30 mm round bore and provides a secure axial stop or component mounting point on metric shafts. The 15 mm width distributes clamping force evenly across the shaft surface without marring.

Sustained Clamping Integrity

Under continuous vibration or cyclic loading the single-piece design maintains its grip without the relaxation that can affect split-hinge alternatives. The 303 stainless steel construction resists corrosion in wash-down or humid environments, preserving clamping torque over extended service intervals. The integral stainless screw eliminates galvanic mismatch between fastener and collar body.

54 mm Outside Diameter Envelope

The collar’s 54 mm outer diameter and 59.2 mm clearance diameter define the radial space required for installation and tool access. Builders working within tight housings or adjacent to bearings must verify that this envelope clears surrounding components. The 15 mm axial width also determines how much shaft length the collar occupies.

Questions about this item

Does the 303 stainless steel clamp collar generate heat or noise during continuous operation?

The 1-piece 303 stainless steel collar has no moving parts, so it produces no heat and no noise when clamped on a 30 mm shaft.

What shaft diameter and tolerance must I already have for the 30 mm bore to clamp correctly?

The collar is made for a 30 mm round bore with no keyway; the shaft must be 30 mm diameter and free of burrs for the stainless screw to grip evenly.

Will the 54 mm outside diameter and 15 mm width clear the adjacent bearings I am keeping on the same shaft?

The collar measures 54 mm OD and 15 mm wide with a 59.2 mm clearance diameter, so check those dimensions against your existing bearing housings.
