Rubber skeleton oil seals generally refer to rotary shaft lip seals, also called shaft seals. In addition, there are reciprocating rubber skeleton oil seals such as shock absorber oil seals and stem oil seals. There is also an oil seal between the two, that is, the rubber seal has both a rotating and reciprocating skeleton oil seal, such as an ultra-high pressure oil seal on a hydraulic motor and a steering machine.
Rubber skeleton oil seals come in many forms, except for the inner skeleton, the exposed skeleton, and the assembled double skeleton oil seal.
In addition, there is no skeleton rubber seal, and no spring-loaded oil seal is also included in the oil seal. The process flow diagram removes the skeleton, adhesive, spring or an unwanted process. In addition, some oil seals, such as assembled exposed skeleton oil seals, are assembled during trimming. Some should also be painted on the side wall of the metal skeleton; some oil seals should be filled with grease between the main and auxiliary lips.
For some special occasions, such as oil seals that require improved wear resistance and reduced friction coefficient, should be halogenated in the halogen solution before hanging the spring. Some oil seals such as AF oil seals need to be glued on the lip. Tetrafluoroethylene film, so the surface treatment and bonding process of Teflon should be added to the process.
