Collar, One-Piece Hex Bore 0.5000", Aluminum, OD 1 1/8"

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 hex bore shaft collar has a 0.5000" bore, 1 1/8" OD, and 0.406" width. Hex bore collars are commonly used in positive drive applications with high torque loads where keyways are not feasible. Tightly controlled face to bore perpendicularity is maintained (TIR of < 0.002") 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 one groove 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 aluminum to a fine burr-free finish for increased screw seating torque. Hardware tests beyond ANSI standards for maximum holding power. It is RoHS and REACH compliant.
