Abstract
A torque transmitting device, such as a fixed constant velocity ball joint as a counter track joint and a method for producing such a joint, in which the curvatures of the bases of the joint tracks deviate in their axial course from the curvatures of the ball contact lines. The method is characterized in that the joint component is brought to an increased hardness by a hardening process prior to the formation of the longitudinal profile of the component, and a diffusion layer is partially or completely removed in the region of the longitudinally profiled structure.
