The design and material selection of high pressure shaft seals are crucial for their performance
high pressure shaft seals. Advanced materials such as polytetrafluoroethylene (PTFE) and silicone rubber are frequently employed due to their excellent resistance to chemicals, temperature fluctuations, and wear. Furthermore, the geometry of the seal must be optimized to withstand the extreme forces exerted by high-pressure fluids while minimizing friction and heat generation.

From a maintenance perspective, the integrity of the outer hub oil seal is paramount. Routine checks during tire rotations or when performing brake services should include an inspection of these seals for signs of cracking, brittleness, or visible leaks.

In addition to material, oil seals are also categorized based on their design and construction. The most common types include lip seals, mechanical seals, and hydraulic seals, each designed for specific applications and conditions. Lip seals are the most basic type and consist of a flexible lip that contacts the shaft to prevent leakage. Mechanical seals, on the other hand, utilize a rotary or stationary face to create a seal, while hydraulic seals are used in hydraulic systems to prevent fluid from leaking
