Hydro-deflector sealing system for a bearing unit

A hydro-deflector bearing unit comprising:

• a stationary radially outer ring;
• a rotatable radially inner ring;
• a plurality of rolling elements interposed between the inner ring and the outer ring;
• and
• two hydro-deflector sealing systems, each positioned on opposite axial ends of the bearing unit, wherein each hydro-deflector sealing system comprises:
• an axially external seal comprising:
• a first radially outer lip formed at a first radial end of the external seal;
• a second radially outer lip positioned radially inner relative to the first radially outer lip, wherein the first and second radially outer lips define a first recess between the first and second radially outer lips;
• a radially inner anchoring lip formed at a second radial end of the external seal distal to the first radial end;
• an intermediate portion connecting the first radial end and the second radial end;
• and
• at least two ridges formed on the intermediate portion and projecting axially outward therefrom,
• wherein the first and second radially outer lips define a W-shaped groove;
• and
• an axially internal seal comprising:
• a primary lip formed at a radially inner end of the internal seal;
• and
• a secondary lip extending radially outward toward the external seal, wherein a gap is defined between a distal end of the secondary lip and the external seal, and a V-shaped recess is defined between the secondary lip and the internal seal.
