Abstract
An axial setting device includes two discs which are centered on a common axis. One is axially supported and the other one is axially displaceable, and at least one is rotatingly drivable. The two discs on their end faces, each have a plurality of circumferential ball grooves. The ball grooves each comprise a depth which decreases in the same direction, and each pair of opposed ball grooves accommodates a ball. At least the ball grooves of one of the two discs, starting from the region of the greatest groove depth, comprise a first groove portion with a greater pitch and an adjoining second groove portion with a smaller pitch, wherein the first groove portion extends over a smaller circular-arch-shaped portion than the second groove portion.
