Mountable Collar, 1pc Clamp, Bore 20mm, Anod Aluminum, OD 40mm OF-MCL-20-AN

Ruland clamp style shaft collars do not mar the shaft, are infinitely adjustable, and have superior holding power when compared to set screw collars. This one-piece mountable shaft collar has a 20mm bore, 40mm OD, and 15mm width. It has machined flats and tapped holes on the top and bottom of the collar allowing users to stack collars on top of each other when shafting must be perpendicular to each other. Users can also mount components such as sensors directly to the collar or mount the collar to metal plates. Tightly controlled face to bore perpendicularity is maintained (TIR of < 0.05mm) which is critical when the collar is used as a load bearing face, mechanical stop, or for component alignment. The work surface is identified by two grooves on the face allowing the user to easily identify which side is precision faced. This collar is stamped with the Ruland name and bore size for ease of identification. It is manufactured from high strength 2025 black anodized aluminum to a fine burr-free finish for light corrosion resistance. Hardware tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
