A resilient annular bearing seal (22,24) having an inner surface defining a central opening, an outer surface defining the seal outer periphery, and first and second side walls between the inner and outer surface and on opposite sides of the seal, the seal further having a circumferentially continuous sealing lip (30,32) extending axially outwardly from the first side wall, the first side wall having a relieved portion (34,36) adjacent to the sealing lip for receiving the sealing lip. The seal may include a sealing shoulder (26,28) adjacent to the outer surface and the first side wall. The seal may also include at least one lip (52,54) extending radially inwardly from the inner surface, and a sealing shield (56,58) adjacent to the first side wall and the inner surface and extending both radially inwardly and axially outwardly. Also, a bearing assembly having an annular outer race (6); an annular housing (10) surrounding the outer race and including side flanges (19,20) extending radially inwardly; an inner race (4) coaxially disposed relative to the outer race; and the annular seals (22,24) of the present invention mounted on either side of the inner bearing race and contacting the outer bearing race, the sealing lips of the seal contacting the housing side flanges. |
