A radial seal arrangement for sealingly engaging an outer surface of a shaft is provided. The radial seal arrangement includes a support member that has a first leg with an outer surface that extends substantially perpendicular to a reference axis. The support member also includes a second leg that extends substantially parallel to the reference axis from the first leg to a first end. The radial seal arrangement further includes a body portion that includes 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 having a relief notch and extending substantially coplanar to the outer surface of the first leg, 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 includes 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 are spaced from each other along a line generally parallel to the reference axis.
