The universal joint assembly is the power-transmission link between the drive shaft and the rotor — it transfers motor torque while compensating installation offset and axial movement during operation. Supplied as one complete kit of every wearing component (parts 1005–1016): steel bushings, O-rings, joint protection sleeves, universal joint pins, spring retainers and fastening rings, in stainless steel or tungsten-carbide-coated options for reduced hinge wear and longer service life.
