Abstract
A return stop includes a rotational inner ring, a stationary, fixed outer ring, and a cage mounted radially between the inner ring and outer ring. The cage has at least two pairs of rollers each having a first and a second roller. A clamping rail is formed on an outer peripheral surface of the inner ring for each roller. A radial recess is formed on the inner ring in the peripheral direction directly adjacent to the respective clamping rail. Also, both of the clamping rails of the roller pairs are formed in the peripheral direction in opposite directions away from each other. In a free-running operation of the return stop, only one roller of each pair of rollers comes into position on the inner ring and the outer ring. The other roller of each pair of rollers does not come into position at least one the inner ring.
