A sealing arrangement for a wheel bearing includes a carrier element connectable to a first bearing part of the wheel bearing, a resilient sealing element, and a counterflow plate connectable to a second bearing part of the wheel bearing. The resilient sealing element includes a resilient main body arranged on the carrier element, first and second axial sealing lips extending away from the resilient main body, and a radial sealing lip extending away from the resilient main body. The counterflow plate is arranged with one side facing the carrier element such that the first and second axial sealing lips, and the radial sealing lip, are in sliding contact with the counterflow plate. The first axial sealing lip, second axial sealing lip, and radial sealing lip rest against the counterflow plate with respective contact pressures.

Sealing arrangement for wheel bearings, and wheel bearing unit comprising a sealing arrangement

A bearing assembly includes an inner bearing ring, an outer bearing ring and rolling bodies located between the inner bearing ring and the outer bearing ring. A gap is defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring. The radially inner surface of the outer bearing ring includes a first radial surface portion that is offset a greater distance from a center of the bearing than a second radial surface portion. The first and second radial surface portions are connected by a sloped surface. A sealing arrangement located in the gap. The sealing arrangement includes a first annular body including an elastomeric sealing protrusion to contact the sloped surface of the outer bearing ring.

Wheel bearing

A sealing arrangement for a wheel bearing having a first bearing part and a second bearing part integrally connected to a wheel bearing flange, and rolling bodies being guided between said bearing parts, includes a carrier element and a stop part. The carrier element is connected to the first bearing part, an elastic element is provided on the carrier element, and the carrier element has a fastening section connected to the first bearing part. The elastic element has a sealing lip. The stop part is fastened to the second bearing part and in sliding contact with the sealing lip. The wheel bearing flange has an axial projection provided such that the projection protrudes in the direction of a cavity formed by an axial projection of the first bearing part. An inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.

Sealing arrangement for a wheel bearing

The invention relates to a seal device () for sealing two bearing elements which rotate relative to each other about an axis (D), in particular for sealing a rolling bearing. The seal device () includes a sealing section () for sealing purposes and a fastening section () for holding the seal device () against a bearing element (). The sealing section () is arranged at one end of the fastening section () and includes a free end (E) opposite thereof. All the sections () have a common carrier element () and at least one sealing element (), and all the sections () extend in the radial direction (R) and/or in the axial direction (A). The fastening section () extends at least partly in the axial direction (A) such that the carrier element () and the sealing element () rest directly against a bearing element () in order to form a clamping seat in the radial direction (R) by the carrier element () in order to hold against a bearing element () and a static seal by the seal element () in order to seal against a bearing element (). The invention further relates to a seal assembly () for a rolling bearing, in particular for a wheel bearing assembly, including a bearing element () and a seal device ().

Seal device and seal assembly

A sealing arrangement for a wheel bearing having a first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which rolling elements are guided, wherein the sealing arrangement has a carrier element which is connected to the first bearing part and wherein a resilient element is provided on the carrier element, wherein the resilient element has at least one sealing lip, and the carrier element has a fastening portion which is connected to an outer circumference of the first bearing part, wherein a sealing ring which forms a seal for the fastening portion is formed on the resilient element, wherein the sealing ring has a cylindrical circumferential surface which abuts the external circumference of the first bearing part.
