Description:

Flexible Jaw Couplings utilize the flexibility and resiliance of a polyurthane element between aluminium hubs. This combination allows high torque to be transmitted with little or no backlash, even where there is significant angular and/or parallel misalignment. This part is the complete coupling consisting of two hubs and a Blue element.
