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.

Next, we discuss the 40% figure, which can denote the allowable leakage rate for particular types of oil seals. Leakage can severely impact the overall performance of mechanical systems, leading to reduced lubrication and increased wear on components. A reputable oil seal must minimize leakage to a level that is often benchmarked at around 40% of the maximum allowable threshold for that system. Manufacturers pour significant resources into developing materials and designs that can achieve this standard, as minimizing leakage not only conserves lubricant but also enhances the efficiency and longevity of the machinery.
