Ruland OD21/33-AT Oldham Coupling Disk, Black Acetal, Bore, 1-5/16\ or 33.3mm OD
- 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)..
- 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..
- Made from acetal for higher torque and torsional stiffness capabilities than nylon..
- Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life..
- Ruland oldham coupling disks are RoHS3 and REACH compliant.
