Description
Axle oil seals are sealing devices used in the drive systems of vehicles such as cars, trucks and engineering machinery. They are mainly installed between the axle and the wheel hub to prevent lubricating oil leakage and prevent external pollutants (such as water, sand, dust, etc.) from entering the transmission system. The function of axle oil seals is to ensure that the lubricating oil of the drive system remains in the proper position, ensure the efficient operation of the power system, and extend the service life of the vehicle. It is widely used in the axle parts of front-wheel drive and rear-wheel drive vehicles, and has excellent sealing, high temperature resistance and wear resistance.

Production
Process
Metal frame manufacturing
Use high-strength metal or reinforced materials to manufacture the oil seal frame to ensure its structural strength and durability.
Rubber molding
According to the design requirements, select appropriate rubber materials (such as NBR, FKM, etc.) for rubber molding to ensure that the sealing lip of the oil seal has good elasticity and wear resistance.
Vulcanization
The vulcanization process enhances the high temperature resistance, wear resistance and aging resistance of rubber, ensuring stable operation in high temperature and high load environments.
Refining
The sealing surface of the oil seal is precision machined to ensure dimensional accuracy and provide better sealing effect.
Quality Inspection
Each oil seal undergoes rigorous testing before leaving the factory to ensure that its temperature resistance, oil resistance, wear resistance and sealing performance meet the standards.
Packaging and delivery
Complete the cleaning and packaging of the oil seal to ensure it is not damaged during transportation.
