ABSTRACT:
An annular sealing groove is provided at an axial end of one of an outer or inner bearing ring. The seal element comprises an annular ring of an elastomeric material with a plurality of circumferentially periodic radially extending projections integrally formed in an outer periphery or an inner periphery thereof. The projections are configured to provide an interference fit in the radial direction with respect to a bottom wall and outer side wall of the sealing groove to effect a seal. Preferably, the radial interference fit of the seal element biases the seal element axially against an inner side wall of the sealing groove.
