Ruland ENCL30-6MM-A is a one-piece shaft collar with a 6mm bore, 30mm OD, and 8mm width. The thin line design reduces weight and allows for use in confined spaces. It has the clamp style benefits of not marring the shaft, easy removability, and indefinite adjustability while commonly being 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. ENCL30-6MM-A is stamped with the Ruland name for ease of identification. ENCL30-6MM-A is machined from solid bar stock to a fine burr free finish and sourced exclusively from North American mills. Ruland uses high grade 2024 aluminium for increased screw seating torque. It is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
