Oldham Sliding Disc Couplings
Oldham sliding disc couplings are mechanical devices that transmit torque and rotation between misaligned shafts, accommodating parallel, angular, and axial misalignment. Comprising two hubs and a central sliding disc, these couplings are ideal for applications requiring precise positioning and minimal backlash, such as servo systems, encoders, and stepper motors. They offer low inertia, high torsional stiffness, and constant velocity operation at high speeds.
