1. A bearing assembly comprising:
an inner bearing ring;
an outer bearing ring;
rolling bodies located between the inner bearing ring and the outer bearing ring;
a gap defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring, the radially inner surface of the outer bearing ring having a first radial surface portion that is offset a greater distance from a center of the bearing assembly than a second radial surface portion, the first and second radial surface portions being connected by a sloped surface; and
a sealing arrangement located in the gap, the sealing arrangement including:
a metallic first annular body configured to contact the sloped surface of the outer bearing ring, including an axially extending first leg being configured for a press fit with the first radial surface portion in an installation position;
wherein the axially extending first leg includes a radially inwardly directed bend that transitions to a radially extending second leg, and, an elastomeric sealing protrusion on the first annular body adjacent to the sloped surface at the radially inwardly directed bend; and
wherein the first annular body further comprises an axially extending third leg extending from a radially inner end of the radially extending second leg to define a U-shaped cross-section, and a first elastomeric lip seal; and
a second annular body including an encoder and having an axially extending fourth leg, wherein the fourth axially extending leg transitions into a radially extending fifth leg, and an axially extending sixth leg extending from a radially outer end of the radially extending fifth leg to define a U-shaped cross-section.
 
14. A bearing assembly comprising:
an inner bearing ring; an outer bearing ring;
rolling bodies located between the inner bearing ring and the outer bearing ring;
a gap defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring, the radially inner surface of the outer bearing ring having a first radial surface portion that is offset a greater distance from a center of the bearing assembly than a second radial surface portion, the first and second radial surface portions being connected by a sloped surface; and
a sealing arrangement located in the gap, the sealing arrangement including:
a first metallic annular body configured to contact the sloped surface of the outer bearing ring, including an axially extending first leg being configured for a press fit with the first radial surface portion in an installation position, the axially extending first leg includes a radially inwardly directed bend that transitions to a radially extending second leg;
wherein the first annular body further comprises an axially extending third leg, extending from a radially inner end of the radially extending second leg to define a U-shaped cross-section, and a first contacting elastomeric lip seal; and
an elastomeric sealing protrusion on the first annular body adjacent to the sloped surface at the radially inwardly directed bend, the elastomeric sealing protrusion contacting the second radial surface portion.
