This bearing forms a clutching-declutching thrust bearing for a motor vehicle and comprises an inner ring, an outer ring and rolling elements. A flange mounted on the inner ring is equipped with two crenellated series of flange segments extending radially on the same side of a cylindrical web of the flange, and being offset angularly about an axis of symmetry of the inner ring, and axially along said axis. In addition to the bearing, the device further includes a control device, provided with a stationary portion and with a moving portion mounted to move axially and suitable for moving the bearing relative to the clutch mechanism, and a protective bellows disposed between the stationary portion and the bearing. The flange segments define between them an annular volume for receiving and for clamping one edge of the bellows.
