Description
Differential oil seals are specially designed for differential seals and are widely used in the transmission systems of cars, trucks and other vehicles. Its main function is to prevent lubricating oil leakage and prevent external dust, moisture and pollutants from entering the differential to ensure the normal operation of the differential. The sealing performance of the differential oil seal is crucial to the service life and operating stability of the vehicle, so high-quality materials are selected to ensure that the oil seal has excellent durability under high load and high temperature environments.

Production
Process
Metal frame manufacturing
Select appropriate metal materials to manufacture the oil seal frame, ensuring the strength and stability of the frame so that it can fit closely with the differential seal groove.
Rubber molding
According to the design requirements of the differential oil seal, select suitable rubber materials (such as NBR, FKM, etc.) for molding to ensure the elasticity and oil resistance of the sealing lip.
Vulcanization
The vulcanization process is used to improve the high temperature resistance, wear resistance and aging resistance of the rubber, ensuring stability in long-term use.
Finishing and assembly
The oil seal lip and inner and outer mounting surfaces are precision machined to ensure the sealing effect and accuracy.
Quality Inspection
Each oil seal is rigorously tested for high temperature resistance, sealing performance, wear resistance, etc. to ensure compliance with standards.
Packaging and delivery
The oil seals are packed after cleaning to ensure safety during transportation.
Standard differential oil seal
Suitable for the sealing needs of conventional automobile differentials, with excellent sealing performance
High temperature differential oil seal
Suitable for use in high temperature environments, using high temperature resistant materials to adapt to the high temperature working environment of the differential
Double lip differential oil seal
The double sealing lip design provides a stronger sealing effect to prevent oil leakage and contaminants from entering.
Customized differential oil seal
Customized according to different differential types, sizes and working environments to meet individual needs
type
Application
Scenario
Used for sealing of automobile drive shafts, wheels, differentials and other parts to prevent oil leakage and protect internal systems
Such as the sealing of gear boxes, hydraulic pumps, compressors and other equipment to ensure that lubricating oil does not leak
