Carefully made by Ruland in Marlborough, MA, Oldham couplings are comprised of two hubs pressed fit with either an acetal or nylon disk. Oldham couplings disengage if the disc breaks, acting as a mechanical fuse. Well-suited for handling large amounts of parallel misalignment. Acetal Oldham coupling inserts are zero-backlash and electrically isolating. Maximum is 4,500 RPM. RoHS and Reach compliant. Also called a Oldham coupling insert, disk, or disc.
