Radial seal arrangement

A sealing assembly, comprising:

• a shaft having an outer surface;
• a housing having an opening configured to receive the shaft, the housing further including a counter bore;
• a radial seal arrangement insertable into the counter bore of the housing, the radial seal arrangement including:
• a support member including a first leg having an outer surface and extending substantially perpendicular to a reference axis and a second leg extending substantially parallel to the reference axis from the first leg to a first end;
• and
• a body portion having an outer peripheral surface extending substantially parallel to the reference axis from the first leg to a point past the first end of the second leg and configured to contact a surface of the counter bore, a first radial face extending substantially coplanar to the outer surface of the first leg, the first radial face including a relief notch, a first sealing portion having a first chamfered surface extending from the first radial face to a first lip, and a second sealing portion separated from the first sealing portion by a first recessed area and separated from the outer peripheral surface by a second recessed area, the second sealing portion including an edge extending substantially perpendicular to the reference axis and a second chamfered surface extending from the edge to a second lip, the first lip and second lip configured to engage the surface of the shaft.

A radial seal arrangement for sealingly engaging an outer surface of a shaft, comprising:

• a support member including a first leg having an outer surface and extending substantially perpendicular to a reference axis and a second leg extending substantially parallel to the reference axis from the first leg to a first end;
• a body portion including:
• an outer peripheral surface extending substantially parallel to the reference axis from the first leg to a point past the first end of the second leg;
• a first radial face extending substantially coplanar to the outer surface of the first leg, the first radial face including a relief notch,
• a first sealing portion having a first chamfered surface extending from the first radial face to a first lip, and
• a second sealing portion separated from the first sealing portion by a first recessed area and separated from the outer peripheral surface by a second recessed area, the second sealing portion including an edge extending substantially perpendicular to the reference axis and a second chamfered surface extending from the edge to a second lip, the first lip and second lip being spaced from each other along a line generally parallel to the reference axis;
• and
• a support element disposed in the second recessed area.
