Ruland Two Piece Shaft Collar, Clamp Screw, Carbon Steel, 12 mm Bore, 28 mm OD, 11 mm Width, OF-MSP-12-F

The Ruland OF-MSP-12-F shaft collar is an industrial-grade two-piece component engineered for securely positioning or guiding rotating shafts. Constructed from high-strength carbon steel and finished with black oxide, this collar offers superior durability and resistance to corrosion, meeting stringent RoHS3 and REACH standards as well as DIN 912 12.9.

Its 12 mm bore diameter allows direct installation onto appropriately sized shafts, providing a precise fit that is crucial for mechanical power transmission systems and other industrial setups. The two-piece clamp style design enables easy installation and removal without marring the shaft surface and allows for adjustments or repositioning as needed, making it highly suitable for maintenance-intensive and modular assemblies.

The outside diameter of 28 mm and width of 11 mm provide optimal surface area for load distribution, while maintaining a compact profile ideal for applications with space constraints. The clamp screw mechanism, equipped with M4 x 12 threaded bores, ensures a reliable grip and consistent alignment under operational stresses. The collar includes OD flats and tapped holes, facilitating direct mounting of adjacent components or additional collars, enhancing overall system modularity.

Equipment manufacturers particularly benefit from the tightly controlled face-to-bore perpendicularity, with Total Indicated Runout (TIR) of ≤ 0.05 mm, ensuring accurate alignment when the collar is used as a load-bearing face, mechanical stop, or for aligning gears and bearings. The design is suited for guiding, spacing, stopping, and mounting applications and finds widespread use in mechanical power transmission, conveyors, automation, material handling, and laboratory machinery.

Applications include industrial equipment manufacturing, automation lines, conveyors, precision assembly machines, laboratory setups, and equipment requiring robust and adjustable shaft fixing points.
