Oil Seal Design

Although there are many styles of Oil Seals, they all generally consist of a flexible rubber lip bonded to a rigid metal case. Most also contain a third element – a garter spring – fitted into the rubber lip to provide additional sealing force, both initially and over the life of the seal. The total radial force of the sealing lip is a function of the rubber pre-tension, coupled with the tensile spring force. The sealing lip may be lathe cut or ready molded, and may feature molded-in hydrodynamic aids to assist sealing in demanding applications. The metal case may be exposed or have rubber molded around it for ease of assembly or improved static sealing.
