Abstract: Radial shaft seal includes an outer diameter member, a primary sealing lip, and a lip energizer. The primary sealing lip is spaced radially from the outer diameter member. The lip energizer is positioned radially between the outer diameter member and the primary sealing lip. The lip energizer moves to an engaging position with the outer diameter member forming a section of material between the outer diameter member and the primary sealing lip. The outer diameter member, the primary sealing lip, and the lip energizer can be formed from a single piece of material, and in one embodiment, an elastomer.

Abstract: Seal with a body that has bilateral symmetry. The body comprises of a first sealing lip on a right side of the body and a second sealing lip on the right side of the body that is positioned radially below and axially inward with respect to the first sealing lip. The body further comprises of a third sealing lip on a left side of the body and a fourth sealing lip on the left side of the body positioned radially below and axially inward with respect to the third sealing lip. In the installed position, the first sealing lip is flexed away from the second sealing lip and the third sealing lip is flexed away from the fourth sealing lip.

Abstract: A metal face seal assembly includes a casing with a first portion that rotates with respect to a second portion. Inside the casing is a face seal assembly with a first seal member that has a first sealing face that rotates with respect to a second seal member that has a second sealing face. At least one loader is provided that is compressible against the casing and exerts a biasing force against one of the first seal member and the second seal member to bias together the first seal face of the first seal member and the second seal face of the second seal member. The first portion and the second portion can each terminate with an annular ring that are separated by a gap for an installation ring positioned in the gap that is removable after installation of the metal face seal assembly.

Abstract: Disclosed is a seal comprising a first sealing surface with a first lip at a terminus of the first sealing surface and a second lip spaced axially apart from the first lip. A third lip is spaced radially apart from the second lip flexes away from the third lip when the seal is installed.

Abstract: A seal has a casing having an outer-diameter surface, an interior facing surface, an exterior facing surface, and a chamfered surface between the exterior facing surface and the outer-diameter surface. A sleeve assembly is positioned radially inward from the casing, and has at least one dust lip that engages an interior side of the chamfered surface for blocking debris from the interior facing surface of the seal. A primary sealing body is positioned radially inward from the casing for blocking debris from the interior facing surface of the casing. The sleeve assembly rotates either with the casing or with respect to the casing.

Abstract: A radial shaft seal for a radial shaft is formed with a casing having an exterior-facing surface opposite from an interior-facing surface, and a sleeve positioned radially inwardly of the casing that rotates with respect to the casing. A sealing ring is connected to the casing, and has an extending portion that interacts with the sleeve to form a labyrinth seal barrier.
