ABSTRACT:
A bearing seal (10) has a casing 11 with a dynamic sealing element (18) such as an EHD at an inner edge. At the outer edge of the casing (11) a static sealing element (14) is provided on an axially extending flange (13). The static sealing element (14) includes opposing outwardly projecting sealing lips (23) which are capable of deflection and which have an outer diameter greater than the diameter of the bearing housing bore when unrestrained. The bearing seal (10) seals the inner and outer race rings of a bearing dynamically and also the outer race ring with the bearing housing statically and positively.
