Description
The crankshaft oil seal is a sealing device specially used for crankshaft components in cars, trucks and industrial machinery. Its main function is to prevent the leakage of lubricating oil inside the engine and prevent external pollutants (such as dust, dirt, moisture, etc.) from entering the engine. The crankshaft oil seal is an important part of the engine sealing system, ensuring a good seal between the crankshaft and other components, extending the service life and performance stability of the engine. The oil seal is generally made of high-performance rubber material with excellent high temperature resistance, oil resistance and wear resistance.

Production
Process
Metal frame manufacturing
The oil seal frame is made of high-strength metal or reinforced material to ensure the strength and durability of the oil seal.
Rubber molding
The oil seal frame is made of high-strength metal or reinforced material to ensure the strength and durability of the oil seal.
Vulcanization
The vulcanization process enhances the high temperature resistance, wear resistance and aging resistance of rubber, ensuring its stable operation in high temperature and high pressure environments.
Finishing and assembly
The sealing surface of the oil seal is precision machined to ensure the accuracy of the size and the sealing performance.
