The jaw coupling convinces by its versatile application options, robust design and damping features. The simple construction effectively sandwiches a buffer piece in the centre of the shaft coupling called an element (made of polyurethane elastomer) between two hubs. The Elements are available in two different hardnesses so that a selection dependant on torque transmission responsiveness and amount of misalignment can be made. The polyurethane elastomer used in the element enables double the torque transmission of our previous jaw coupling (Miki comparison), and since the design pre-compresses the element, it can also be used without backlash. Aluminum alloy is used as the hub material. The hub may be coupled to the shaft either by key way or by integral clamp.
