Ruland MSP-50-SS is a two-piece shaft collar with a 50mm bore, 78mm OD, and 19mm width. The clamp style design does not mar the shaft, is easy to remove, and is indefinitely adjustable. MSP-50-SS is commonly used for guiding, spacing, stopping, mounting, and component alignment. Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity of Ruland shaft collars, TIR of ≤ 05mm. Perpendicularity is critical for alignment when the shaft collar is used as a load bearing face, mechanical stop, or for mounting components such as gears or bearings. Proprietary processes have been developed by Ruland to maintain superior fit, finish, and holding power.
