This section will allow you to select disks to be used individually or as part of an assembly. Ruland offers users the ability to tailor the performance of oldham couplings to match their application needs as disks are available in three materials, acetal for high torsional stiffness and zero-backlash, nylon for shock absorption and noise reduction, and PEEK for high temperature and low outgassing. The slots of the disk mate onto the tenons of the hub with a slight press fit to allow the coupling to operate with zero backlash. In the event of disk wear or failure, the disk can be easily replaced and the oldham coupling's original performance restored. Disks with a center hole are available upon request to allow full shaft penetration.
