Abstract
A contaminant-resistant bearing assembly includes a multi-lip seal with an extended shroud supported from the outer ring and projecting adjacent a stepped inner ring shoulder. A steel slinger supported from the inner ring is offset outwardly adjacent the shroud and includes a radially outer edge terminating closely adjacent the connection of the seal shroud to the outer ring. The slinger includes an outer portion angled inwardly from the radial direction and supporting a lip seal which contacts an angled portion of the seal shroud at a central location between the rings. A primary step machined on the inner ring prevents the slinger from being pushed into the seal.
