Ruland Manufacturing MSP-25-SS 2-Piece Clamp Shaft Collar 25 mm 303 SS

Precision shaft collar for 25 mm metric shafts

The Ruland Manufacturing MSP-25-SS is a two-piece clamp collar machined from 303 stainless steel. It fits round bores of 25 mm and provides axial positioning or component mounting on metric shafts. The split design allows installation or adjustment without removing other shaft-mounted parts, making it suitable for maintenance-sensitive assemblies and prototype work where frequent repositioning is required.

Stainless construction resists corrosion without

Grade 303 stainless steel on both the collar halves and the clamp screws provides inherent corrosion resistance in wet or chemically aggressive environments. The material eliminates the need for protective coatings or regular lubrication, reducing contamination risk in clean-room or food-adjacent machinery. The two-piece clamp distributes holding force evenly around the 45 mm outside diameter, minimising shaft marring while maintaining secure grip under vibration.

Supplied as a complete clamp assembly

The collar ships as a single 25 mm bore unit with integrated stainless steel screws, requiring no additional hardware for immediate use. The 15 mm width and 52.1 mm clearance diameter define the installed envelope, allowing the designer to verify fit against adjacent components. No specialised tools beyond standard hex keys are needed for tightening, and the absence of keyways or threaded bores simplifies inventory for shops standardising on plain round shafts.
