Abstract
The invention relates to a wheel bearing arrangement, comprising at least one encoder, at least one sensor, a seal arranged concentrically to the rotational axis and a hub mounted to rotate in the wheel bearing arrangement, whereby a radial flange on the hub, faces radially away from the rotation axis and the seal seals at least one radial annular gap around the hub on the side of the radial flange. The seal comprises at least one cover ring, made from a non-ferromagnetic material and at least one elastic first sealing lip, the first sealing lip is fixed to the cover ring and makes sealing contact with the encoder and at least one signal-active part of the encoder is arranged on the inside of the seal and rotates about the rotational axis with the hub.
