Abstract
A sealing device for providing a seal between two relatively rotatable bearing components includes an annular ring having a radially inner and a radially outer flange. The flanges extend axially to define an annular channel. An annular wiper element is disposed in the channel so as to axially extend beyond the flanges. The annular ring is positioned axially adjacent to the rotational interface between the two bearing components so that the annular ring rotates with one bearing component and the wiper element is in surface contact with the other bearing component.
