Abstract

A wheel bearing has inner and outer bearing rings each having a radially outwardly directed flange, and a plurality of rolling elements arranged between the rings. An annular seal has a support element affixed to the outer ring, the support element terminating in an annular elastic element of oil resistant material that is slidably engages the inner ring. A cover extends over the flange of the inner ring and has an end terminating radially spaced from a shoulder of the outer ring, to define a sealing gap. The intermediate portion of the cover defines a lubricant accumulation space.
