Patent ID: 7927018

Claim:
A wheel bearing arrangement comprising: a rotationally fixed inner part; an outer part positioned radially outward of the inner part and rotationally movable with respect to the inner part about a rotational axis, a radial annular space between the inner part and the outer part; an encoder positioned in the radial annular space and configured to be rotationally movable with the outer part about the inner part, the encoder comprising an annular section and having a distal end facing the inner part and positioned directed axially toward a sensor for detecting a rotation of the encoder; a protective plate positioned between the encoder and the sensor to at least partially cover in an axial direction the annular space; and an elastic sealing lip positioned at the distal end of the encoder and including magnetizeable additives, wherein the elastic sealing lip comprises alternately polarized magnetic particles dispersed through the sealing lip.
