Abstract
A bearing arrangement for a wheel hub of a motor vehicle, which wheel hub can be driven by a rotary joint. In the bearing arrangement, the wheel hub, which is connected to a wheel flange, and the rotary joint, which is connected to a drive shaft, are connected for conjoint rotation to one another and to a double-row rolling element bearing mounted on the wheel hub, the rolling element bearing having at least one separate inner bearing ring which is arranged axially outward, points towards the rotary joint, and which is axially pretensioned by a collar of the wheel hub impinging on an end face of the inner bearing ring. A sealing ring made of sheet metal rests on the inner bearing ring, and includes a sealing element that rests sealingly on the rotary joint. The sealing element has a sealing lip provided with a plurality of recesses, distributed uniformly in the circumferential direction on the sealing lip and are separated from one another by bars in order to achieve a reduced friction between the sealing lip and the rotary joint when the sealing ring is slid onto the rotary joint.
