A rolling-element bearing unit for a wheel bearing assembly of a vehicle, comprising:
- a first rolling-element bearing having an outer bearing ring and an inner bearing ring and rolling elements disposed between the outer bearing ring and the inner bearing ring;
- a first seal element having a seal-element base body having a first support member mounted to an axial outer surface of the inner bearing ring and a first seal lip pressed against a radial end surface of the outer bearing ring to hold the outer bearing ring in position relative to the inner bearing ring.
A wheel bearing assembly of a vehicle comprising:
- a housing having a first opening and a second opening opposite the first opening and a first annular wall and a second annular wall in the housing between the first opening and these second opening;
- a first rolling-element bearing unit and a second rolling-element bearing unit, each of the first rolling-element bearing unit and the second rolling element bearing unit comprising a first rolling-element bearing having an outer bearing ring and an inner bearing ring and rolling elements disposed between the outer bearing ring and the inner bearing ring and a first seal element having a seal-element base body having a first support member mounted to an axial outer surface of the inner bearing ring and a first seal lip pressed against a radial end surface of the outer bearing ring to hold the outer bearing ring in position relative to the inner bearing ring and a radial end surface on a side of the seal-element base body axially opposite from the first seal lip;
- the first rolling-element bearing unit being inserted in the first opening of the housing with the outer bearing ring of the first rolling-element bearing in contact with the first annular wall and the second rolling-element bearing unit being inserted in the second opening of the housing with the outer bearing ring of the second rolling-element bearing in contact with the second annular wall and with the inner ring of the second rolling-element bearing forming a butt joint with the inner ring of the first rolling-element bearing and with the radial end surface of the seal-element base body of the first rolling-element bearing in contact with the radial end surface of the seal-element base body of the second rolling-element bearing.
