In addition to the materials used, the design of high temperature shaft seals is also crucial for their performance. The seal must effectively block the passage of fluids or gases through the interface between the moving shaft and stationary housing. This requires precise engineering to ensure a tight fit and proper sealing under varying temperature and pressure conditions.

An oil seal has two tasks: Keeping the lubricant in and keeping dirt and contaminants out of rotating components. This separation must be accomplished between surfaces in relative motion, usually a shaft or bearing inner ring and a housing. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.
