  • Ruland oldham coupling disks are RoHS3 and REACH compliant
  • Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life.
  • Made from acetal for higher torque and torsional stiffness capabilities than nylon.
  • 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.
  • Ruland oldham couplings have a zero-backlash balanced design for reduced vibration at speeds up to 4,500 RPM. They can accommodate high amounts of parallel misalignment (up to 10% of the hub OD).
