Oil seal is mainly used for sealing lubricating oil. It is a mechanical component used to seal grease, isolating the parts that need lubrication in the transmission components from the output components to prevent lubricant leakage.
Oil seals are divided into two types: static seals and dynamic seals (usually reciprocating). The common form of oil seal is TC oil seal, which is a double lip oil seal with a self tightening spring completely wrapped in rubber.
Material of oil seal
