Description
Simple, inexpensive and very common in European machinery where dimensions have become interchangeable, for example in many cases with KTR Rotex . A simple 3 piece coupling will have two cast iron or aluminium hubs and a polyurethane element for torques 11 to 1465Nm, shafts 14 to 90mm. More sophisticated variants include clamp hubs which can have zero backlash and compact high torque models. Different grades of element, for example rubber, hytrel and bronze can vary the torsional softness and misalignment capacities.
