wheel hub seal. This noise is caused by the lack of lubrication in the wheel hub, which can lead to metal-on-metal contact and damage.
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.
