The OEP type UA Oldham/Universal coupling differs from other versions of the Oldham/Universal coupling (UC and UI) in that its midsection is machined from metal bar, the same alloy as the hubs. The UA is a strong, stiff, robust coupling, and can easily be configured for larger or non-standard sizes.
A Delrin© (or higher temperature plastic) replaceable wear bushing between the cylindrical fins on the hub and the cylindrical slots in the midsection provide smooth, low-friction, low-reactive-force flexion with zero backlash. These wear bushings include very small holes that serve as a grease reservoir. The placement of the bushings mounted within a machined metal midsection, enable the coupling to transmit great amounts of torque.
These couplings protect support bearings by exerting consistently low reactive forces, even under large misalignments. They accommodate large radial misalignment in a short length.
