Oil seals are used in a wide range of applications, from automotive engines and transmissions to industrial machinery and household appliances. In vehicles, for instance, oil seals are commonly found in engines, differential housings, and wheel bearings. Their presence is critical in ensuring that these components operate efficiently and safely.
The design of high pressure rotary seals considers several key factors, including the type of fluid being sealed, operating temperature, pressure, and the speed of rotation. Typically, they are made from advanced materials like elastomers, PTFE (polytetrafluoroethylene), and specialty composites that can endure extreme conditions. The seal's design often incorporates a lip that makes contact with the rotating shaft, creating a barrier against the pressure.
Applications and Importance
- U-Cup Seals Shaped like the letter U, these seals provide excellent sealing capabilities for low to medium pressures. They are particularly effective in dynamic applications, where they can maintain a consistent seal against the piston even under motion.
