The primary function of axle hub seals is to retain lubrication. Proper lubrication is essential for the smooth operation of moving parts, reducing friction and wear. Without effective sealing, the lubricant can leak out, leading to inadequate lubrication of the gears and bearings, which may cause premature wear and eventual failure of the components.

Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

The applications of high temperature oil seals span a wide range of industries. In the automotive sector, they are commonly used in engine components, transmission systems, and various driveline applications. High temperature seals are essential in maintaining the integrity of systems that operate under extreme thermal conditions, such as turbochargers, where exposure to high temperatures is prevalent. Additionally, in the aerospace industry, these seals are crucial for ensuring the reliability of engines and hydraulic systems, where failure can lead to catastrophic consequences.
