Abstract
A wheel bearing arrangement that has a wheel hub, which is operatively connected to an outer ring by way of rolling elements and a wheel flange. The wheel flange, together with a protective ring forms a first gasket. The protective ring surrounding the outer ring of the wheel hearing arrangement. This approach is of particular interest for non-driven wheel bearing arrangements in which the side of the wheel bearing facing the vehicle can be protected by a cover used on the vehicle side.
