This coupling combines the sliding mechanism of the Oldham and the pivotal action of the universal joint to combat angular and radial misalignment. A series of integral pins engage a pair of injection moulded annular rings with controlled preload to eliminate backlash. The Uni-Lat has a generous angular and radial misalignment capacity and is electrically isolating. Applications are usually general purpose, light duty stepper (half and full step) encoder, resolver and tachogenerator drives and light push/pull duties.
