Ruland MSP-12-ST is a two-piece shaft collar with a 12mm bore, 28mm OD, and 11mm width. The clamp style design does not mar the shaft, is easy to remove, and is indefinitely adjustable. MSP-12-ST 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. MSP-12-ST is stamped with the Ruland name and bore size for ease of identification. Halves are mated throughout the manufacturing process for proper fit and alignment. MSP-12-ST is machined from solid bar stock to a fine burr free finish and sourced exclusively from North American mills. Ruland uses 316 stainless steel with hardware of like material for consistent corrosion resistance. Stainless steel hardware undergoes a proprietary surface treatment process to prevent galling. It is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
