摘要： 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.

摘要： A method of fabricating a fluid seal for sealing a relatively rotatable member, wherein the fluid seal has an elastomeric sealing member bonded to a PTFE insert. A wafer of PTFE material has a body portion and an end portion of a greater thickness than the body portion. The wafer is placed in a mold cavity with one side of the wafer opposed to a surface portion of the mold cavity. Elastomeric material is forced into the mold cavity to form a molded preform of the elastomeric sealing member and bond the preform to an opposite side of the wafer. The molded preform and bonded wafer are removed from the mold cavity. The end portion of the wafer and an end portion of the preform are trimmed to form the fluid seal.
