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.

Radial shaft seal

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.

Unitary face seal assembly

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.
