Oldham Couplings
  • Provide electrical isolation for encoders, tachometers, linear stages, stepper motors, and servomotors. Drive tenons mate to torque-transmitting disc. Like a mechanical fuse, coupling disengages when disc fails. Hubs are low-inertia black anodized aluminum. Select nylon discs for shock absorption; select acetal discs for high torsional rigidity and zero backlash.
  • Complete assembly requires 2 hubs and 1 disc of the same O.D. (sold separately) Max. rpm: 4500 Max. angular misalignment: 0.5
