A rotary shaft seal comprising: - an annular body having an aperture defining a central axis and an inner surface; the annular body defining an outer member having a first end and a second end, a first flange disposed proximate the first end of the outer member and extending radially inward from the outer member, and a second flange disposed proximate the second end of the outer member and extending radially inward from the outer member, wherein the annular body has a C-shaped cross section; - a sealing element positioned at least partially within the annular body, wherein the sealing element is configured to extend radially and form a seal between the annular body and a shaft disposed within the aperture of the annular body, wherein the sealing element defines a first flange and a second flange, wherein the first flange of the sealing element is disposed between the first and second flanges (18, 20) of the annular body, wherein the sealing element has a generally U-shaped or generally V-shaped cross section when viewed in a direction perpendicular to a plane extending radially from the central axis; and - a biasing element biasing at least a portion of the sealing element in a radial direction, wherein the biasing element comprises a generally L-shaped cross section, a generally V-shape cross section, a generally U-shape cross section, a generally C-shape cross section, or any combination thereof, when viewed in a direction perpendicular to a plane extending radially from the central axis; wherein the annular body comprises an outer diameter that is configured to provide a seal against a housing in which the annular body may be disposed, wherein an axial end of the first flange of the sealing element is directly adjacent along its entire thickness to an inner side of the first flange of the annular body without the biasing element therebetween, wherein an axial end of the biasing element is directly adjacent along its entire thickness to an inner side of the first flange of the annular body, wherein the biasing element is positioned at least partially along an inner surface of the first flange of the sealing element such that the biasing element provides a radial biasing force to the first flange or to the first and second flanges (24 and 26) of the sealing element. - an annular body having an aperture defining a central axis and an inner surface; the annular body defining an outer member having a first end and a second end, a first flange disposed proximate the first end of the outer member and extending radially inward from the outer member, and a second flange disposed proximate the second end of the outer member and extending radially inward from the outer member, wherein the annular body has a C-shaped cross section; - a sealing element positioned at least partially within the annular body, wherein the sealing element is configured to extend radially and form a seal between the annular body and a shaft disposed within the aperture of the annular body, wherein the sealing element defines a first flange and a second flange, wherein the first flange of the sealing element is disposed between the first and second flanges (18, 20) of the annular body, wherein the sealing element has a generally U-shaped or generally V-shaped cross section when viewed in a direction perpendicular to a plane extending radially from the central axis; and - a biasing element biasing at least a portion of the sealing element in a radial direction, wherein the biasing element comprises a generally L-shaped cross section, a generally V-shape cross section, a generally U-shape cross section, a generally C-shape cross section, or any combination thereof, when viewed in a direction perpendicular to a plane extending radially from the central axis; wherein the annular body comprises an outer diameter that is configured to provide a seal against a housing in which the annular body may be disposed, wherein an axial end of the first flange of the sealing element is directly adjacent along its entire thickness to an inner side of the first flange of the annular body without the biasing element therebetween, wherein an axial end of the biasing element is directly adjacent along its entire thickness to an inner side of the first flange of the annular body, wherein the biasing element is positioned at least partially along an inner surface of the first flange of the sealing element such that the biasing element provides a radial biasing force to the first flange or to the first and second flanges (24 and 26) of the sealing element.
