摘要： 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.

摘要： A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air-side of the shaft seal from an oil-side of the shaft seal is provided. The seal includes an annular mounting portion and a seal lip operably attached to the mounting portion. The seal lip has an annular inner sealing surface extending axially between an oil-side end and a free air-side end. The inner sealing surface has a first groove region extending along the shaft in sealed engagement therewith and a second groove region extending along the shaft in sealed engagement therewith. The first groove region and the second groove region are spaced axially from one another by an intermediate non-grooved region. The first groove region is configured to direct contamination toward the air-side of the seal and the second groove region is configured to direct lubrication toward the oil-side of the seal.

摘要： A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air-side of the shaft seal from an oil-side of the shaft seal is provided. The seal includes an annular mounting portion; an elastomeric seal body connected to the mounting portion, and a seal lip connected to the seal body. The seal lip has an annular inner sealing surface extending axially between an oil-side end and a free air-side end. The inner sealing surface has a first groove region and a circumferentially continuous annular static band. The first groove region is spaced axially from the static band and extends between the static band and the oil-side end to pump lubrication toward the oil-side of the seal. The static band prevents the lubrication from leaking from the oil-side to the air-side of the seal.

摘要： A radial shaft seal to isolate an air side of the seal from an oil side of the seal is provided. The seal includes a mounting portion and a seal lip having a sealing surface extending between an oil side end and an air side end. An annular bridge is connected to the oil side end by a first hinge and to the mounting portion by a second hinge. The bridge extends in overlying relation to the seal lip. A projection extends from the first hinge away from the bridge. A plurality of ribs extend radially inwardly from the projection. A plurality of nubs extend axially from the oil side end of the seal lip toward the oil side of the shaft seal. The ribs and nubs minimize friction between the seal and a shaft during installation and prevent the seal lip from inverting during an oil-side installation assembly.

摘要： A shaft seal assembly includes a metal case having an annular leg extending radially inwardly to a free end with opposite oil and air sides of the leg facing respective oil and air sides of the seal assembly. An elastomeric material bonded to the leg forms a main body adjacent the free end and a primary seal lip radially inwardly from the main body. The primary seal lip has a sealing surface that extends between an air side end and free oil side end. The air side end is attached to an annular bridge via a first hinge and the bridge is operably attached to the main body via a second hinge. The first and second hinges each have a thickness that is less than a thickness of the bridge and the thickness of the first hinge is less than a thickness of the primary seal lip.
