OD21/33-AT Ruland Oldham Coupler Insert Ruland OD21/33-AT is an oldham coupling disk designed to fit hubs with an OD of 1.000" (25.4mm). It is a component of a three-piece design consisiting of two anodized aluminum hubs press fit onto a center disk. This three-piece design allows for a highly customizable coupling that easily combines clamp or set screw hubs with inch, metric, keyed, and keyless bores. OD21/33-AT is made from acetal for zero-backlash and high torsional stiffness. Oldham couplings can accommodate all forms of misalignment and are especially usefule in applications with high parallel misalignment (up to 10% of the coupling OD). They operate with low bearing loads protecting sensitive system components such as bearings and have a balanced design for reduced vibration at speeds up to 6,000 RPM. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. Ruland Oldham Coupling Insert Diagram
