A coupling element is arranged at the bearing's axial side facing the bearing support. The coupling element includes a first, preferably nose-shaped, radial protrusion that is in engagement with the first groove, and a second radial protrusion, which at least partially encompasses the bearing support at a side facing away from the bearing, so that the coupling element fastens the bearing to the bearing support. A coupling element for such a bearing arrangement is also provided.
