  • Publication number: 20240060536
    Abstract: 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.

  • Publication number: 20230383791
    Abstract: 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.

  • Publication number: 20230003257
    Abstract: 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.

  • Publication number: 20220397157
    Abstract: An encoder for a wheel bearing includes a carrier plate ring and a magnetic encoding ring. The carrier plate ring has a radially running first leg, and an axially running second leg arranged on an outer ring or on an inner ring of the wheel bearing. The carrier plate ring has, on the radially running first leg, cut-outs distributed over its circumference. The first leg has a fold for forming a folded portion, and the folded portion at least partly covers the cut-outs. The carrier plate ring is at least partly surrounded by the magnetic encoding ring. The encoding ring has unipolar magnetization and at least partly comes into contact in the cut-outs.

  • Patent number: 11092239
    Abstract: The invention relates to a seal device (1) 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 (1) includes a sealing section (2) for sealing purposes and a fastening section (3) for holding the seal device (1) against a bearing element (21). The sealing section (2) is arranged at one end of the fastening section (3) and includes a free end (E) opposite thereof. All the sections (2, 3) have a common carrier element (4) and at least one sealing element (5), and all the sections (2, 3) extend in the radial direction (R) and/or in the axial direction (A).
