The seal may include a sealing shoulder adjacent to the outer surface and the first side wall. The seal may also include at least one lip extending radially inwardly from the inner surface, and a sealing shield 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; an annular housing surrounding the outer race and including side flanges extending radially inwardly; an inner race coaxially disposed relative to the outer race; and the annular seals 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.
