Jaw Coupling [Huco 818.20.0000] (Spider Coupling), 20mm OD. Pilot Bore, no fastening, with medium element
Item number:
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 White element.
