Abstract

A wheel bearing assembly for a vehicle includes at least one rolling-element bearing having a first bearing ring and a second bearing ring defining therebetween a bearing interior, rolling elements disposed in the interior, and a seal assembly for sealing the bearing assembly. The seal assembly includes a sleeve-shaped element connected to the second bearing ring such that the sleeve-shaped element rotates with the second bearing, and the sleeve-shaped element includes a flange that forms an axial stop for the rolling elements. A carrier element is connected to the first bearing ring such the carrier element rotates with the first bearing ring, and the carrier element includes a radially extending annular flange. The radially extending annular flange supports a radially encircling seal having at least one seal lip, and the seal lip extends toward the second bearing ring and sealingly abuts on the sleeve shaped element.
