Hebei Hankai hydraulic gear pump seal kit

A rear hub seal is an essential component of a car's rear axle system. It is responsible for keeping the lubricating oil inside the axle housing while preventing dirt, water, and other contaminants from entering. Without a properly functioning rear hub seal, the axle could suffer from lack of lubrication, leading to increased wear and tear on the components and potential failure.

Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.

Skeleton oil seals are widely used in various applications, including automotive, aerospace, and industrial machinery. In the automotive sector, they can be found in engines, transmissions, and differential components. Their ability to prevent oil leakage is vital for maintaining engine performance and longevity. Similarly, in aerospace applications, these seals are essential for ensuring that hydraulic and fuel systems operate efficiently without contamination.

4. Outer Diameter The outer part of the seal fits snugly into the housing, preventing external contaminants from entering the system.
