Ruland oldham couplings have a zero-backlash balanced design for reduced vibration at speeds up to 4,500 RPM. Keyway is used on this coupling for additional torque transmission capabilities and to prevent slippage on the shaft.
Can accommodate high amounts of parallel misalignment (up to 10% of the hub OD). Acts as a mechanical fuse stopping power transmission during a torque overload.
User can combine clamp or set screw hub with inch, metric, keyed, or keyless bore for a high level of customization. Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life
Made from high strength 2024 aluminum with a black anodized finish for light weight and low inertia.
Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities. Ruland oldham couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant.
