The main material of the differential oil seal is usually rubber or elastomer, which consists of three main components: spring, metal skeleton and sealing material. The spring ensures that the seal lip remains in constant contact with the shaft, while the metal skeleton provides structural rigidity. The sealing material is usually made of rubber or elastomer to form a sealing lip that prevents fluid leakage.
The role of oil seals is twofold: on the one hand, they prevent the leakage of lubricants; On the other hand, they remove contaminants from the engine's mechanical system. These seals are used in cars to seal gaps between moving parts and prevent liquid leaks
