Abstract
A bearing unit includes two hydro-deflector sealing systems, each positioned on opposite axial ends of the bearing unit. Each hydro-deflector sealing system includes an external seal having a first radially outer lip, a second radially outer lip, and a radially inner anchoring lip formed at an opposite end. An angled connecting portion connects the second radially outer lip to an intermediate portion that extends to the radially inner anchoring lip. At least two ridges are formed on the intermediate portion. The first and second radially outer lips and the angled connecting portion define a W-shaped groove that deflect contaminants away. The hydro-deflector sealing system also has an internal seal having a primary lip, an anchoring lip formed, an intermediate portion connecting the primary lip and the anchoring lip, and a secondary lip toward the external seal that does not contact the external seal under normal operating conditions.
