Ruland MCLH-100-F, 100mm Heavy Duty Shaft Collar, Black Oxide Steel, One-Piece Clamp Style, 140mm OD, 32mm Width


Ruland MCLH-100-F is a one-piece shaft collar with a 100mm bore, 140mm OD, and 32mm width. The clamp style design does not mar the shaft, is easy to remove, and is indefinitely adjustable. It is commonly used for guiding, spacing, stopping, mounting, and component alignment. Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity (TIR of ≤ .002"). 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. MCLH-100-F is stamped with the Ruland name and bore size for ease of identification. This heavy duty shaft collars have larger ODs and screws for higher holding power. Forged screws test beyond DIN 912 12.9 standards to ensure maximum holding power. MCLH-100-F is machined from solid bar stock to a fine burr free finish and sourced exclusively from North American mills. Ruland uses 1215 lead-free steel with a proprietary black oxide finish that produces a fine glossy finish while increasing holding power and resisting corrosion. It is RoHS2 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
