Shaft seals serve as barriers between rotating shafts and stationary components. They are integral in containing lubricants and preventing external contaminants from entering the machinery. In high-temperature environments, the challenges are amplified. High temperature shaft seals must resist thermal degradation, maintain their sealing properties, and endure the harsh conditions often present in such settings.

Conclusion

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.
