The company has developed a sealing device for wheel bearings, which has a first support part and a second support part. The second support part is integrally connected to the wheel bearing flange, in which a rolling element is guided between the support parts. The sealing device includes the following: a bearing element, which is connected to the first support part, and an elastic element is arranged on the bearing element, The elastic element has at least one sealing lip, wherein the bearing element has a fastening section connected to the first support part, a stop part, which is fastened to the second support part, and at least one sealing lip is in sliding contact with the stop part, wherein the wheel bearing flange has an axial protrusion, The axial protrusion of the wheel bearing flange is arranged such that the protrusion protrudes in the direction of the cavity formed by the axial protrusion of the first support part, and the inner surface of the axial protrusion of the wheel bearing flange forms a seat for the stop part.
