ABSTRACT:
A shaft seal for forming a dynamic seal along an axially extending annular running surface and method of installation thereof is provided. The shaft seal has a mounting portion configured to be connected to a stationary housing and a seal lip having an annular sealing surface extending between an oil side end and an air side end of the seal lip. The sealing surface is configured to extend axially along a shaft running surface. An annular bridge portion connects the seal lip to the mounting portion. A plurality of webs extend generally radially between the bridge portion and the mounting portion to prevent the seal lip from being inadvertently unfolded during installation or while in use. An annulus can be used to install the shaft seal into a housing and about a shaft without the need for secondary operations.
