The document introduces a cross-disc coupling called NK. This coupling is made of steel and is suitable for driving slow-running rotary cam switches. It can compensate for axial, radial, and angular displacements. The mechanical data of the coupling includes information about flanges, cross-disc, retaining bolts, etc., as well as maximum speed, maximum torque, and other limitations. The coupling requires no maintenance and can be used in any fitting position.
