Abstract
A bearing assembly having primary seals between inner and outer races on opposite sides of roller elements and an auxiliary face seal on at least one end thereof. The auxiliary seal includes a cap fixed to the inner race, and axially movable face seal member disposed within the cap for rotation therewith, and a resilient O-ring biasing and sealing member interposed between the face seal member and the cap for biasing the face seal into sealing contact with the outer race. The face seal, resilient sealing and biasing member, and cap define a multiplicity of seal barriers for preventing solid and liquid contaminants from entering the bearing assembly and reaching the primary seal.
