Description
The wheel hub oil seal is a sealing element specially designed for the wheel hub of automobiles, engineering machinery and other equipment. Its main function is to prevent the leakage of lubricating oil at the wheel hub bearing, and effectively prevent moisture, dust and other pollutants from entering the bearing, thereby protecting the bearing from damage and extending its service life. Wheel hub oil seals are usually made of high-performance rubber materials and equipped with metal frames, which can withstand high loads, high speeds and harsh environmental conditions. It is widely used in industries such as automobiles, trucks, engineering machinery, especially in wheel hub bearing systems that require long-term stable operation.

Production
Process
Metal frame manufacturing
The oil seal frame is made of high-strength metal materials, such as stainless steel or carbon steel, to ensure that it has sufficient strength and stability to adapt to the high-load environment of the wheel hub.
Rubber molding
Select suitable rubber materials (such as NBR, FKM, etc.) and form the sealing lip part through injection molding or pressing process.
Vulcanization
The vulcanization process is carried out to improve the high temperature resistance, oil resistance, wear resistance and aging resistance of the rubber, ensuring that the oil seal can work stably for a long time in harsh environments.
Finishing and assembly
The sealing lip and mounting surface are processed carefully to ensure the sealing effect and installation accuracy.
Quality Inspection
Each oil seal is subjected to strict quality inspections, including temperature resistance, sealing, wear resistance, etc., to ensure compliance with standards.
Packaging and delivery
After strict inspection, the products are packaged to ensure safety during transportation.
