Oil Seal is a mechanical components that used to seal oil (oil is the most common transmission system liquid material), It`s isolated the lubricated components with other components, not let the lubricate oil leakage. 

Oil Seal is generally divided into single-type and assembly type, assembly type is the skeleton and lip material can be free combination, generally used for special oil seals.

Oil seal can have different names, customary general rotary axis lip seal called oil seal, the static seal and dynamic seal (general reciprocating motion) was called seal parts.

The representative form of oil seal is TC type, is a double lips oil seal with a fully rubber coated and garter spring, generally speaking oil seal refers to TC skeleton oil seal, skeleton oil seal diagram see Figure:
