Abstract
A prestressing unit which has a first ramp disk and a second ramp disk. Ramp contours are formed in one side of an annular face of the ramp disks. In the prestressing unit, the rolling bodies ascend and/or descend on the ramp contours as a result of rotational pivoting of one of the ramp disks in relation to the other ramp disk about an axis. The ramp contours are each formed as a single-part running face for the rolling bodies. The running face is inclined with respect to the axis.
