The Hadeflex F coupling is a torsionally flexible, flexible and encapsulated claw coupling made of grey cast iron with elastomer elements.

These rubber elements made of NBR are the heart of the elastomer coupling. They transmit the torque and compensate for axial, radial and angular shaft misalignments. If the flexible elements are destroyed by overload or advanced wear, input and output are separated from each other.

The Hadeflex F cam coupling is available in two different designs. The coupling type FW is a two-piece design consisting of a pocket part (part 1) and a one-piece claw part (part 2). 

The shaft coupling type FNW is a three-part design consisting of a pocket part (part 1) and a screwed claw part (part 4+5). This design allows easy replacement of the coupling sets without dismantling the coupling hubs or the motor.

The coupling hubs are standard for cylindrical finish bores with keyway and set screw, which we insert according to customer specifications. In addition, special bores or profile splines are also possible on request.
