18mm Diameter UniLat Offset Coupling
Item number:
Description:
The Universal/Lateral Offset 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. This style is designed for use with small bores.
Select bore(s) before adding to cart (prices will change if keyways are selected).
