Abstract
A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air side of the seal from an oil side of the shaft seal is provided. The seal includes a mounting portion and a seal lip having an annular sealing surface extending between an oil side end and a free air side end. An annular bridge is connected to the oil side end of the seal lip by a first hinge and to the mounting portion by a second hinge. The bridge extends from the first hinge to the second hinge in radially overlying relation to the seal lip. A projection extends from the first hinge away from the bridge toward the oil side of the seal to prevent the seal lip from inverting during the oil-side installation assembly.
