The first figure, 22%, typically refers to the efficiency rate of a sealing system. In many mechanical applications, oil seals operate under various conditions and stresses. A 22% efficiency rating means that seals must be capable of withstanding fluctuations in temperature and pressure, ensuring that the lubricating oil remains contained. A higher efficiency rate often translates to a longer lifespan for machinery, thus saving costs in maintenance and potential downtime.

The performance of high pressure hydraulic shaft seals largely depends on the materials used in their construction. Common materials include nitrile rubber (NBR), fluorocarbon (FKM), polyurethane (PU), and PTFE (Teflon). Each material has unique properties that make it suitable for specific temperature ranges, chemical exposures, and pressure levels.

Applications of High Pressure Rotary Seals

Cylinder seal kits are integral components in various hydraulic and pneumatic systems. These kits play a crucial role in ensuring the optimal performance and durability of machinery by preventing leaks and maintaining pressure in hydraulic cylinders. The importance of cylinder seal kits cannot be overstated, as they are essential for the efficiency, reliability, and safety of equipment used in several industries, including construction, manufacturing, and automotive.

3. Polyurethane Seals (PU) These seals offer excellent wear resistance and are often used in high-load applications. Their higher cost may be justified by their superior performance and longevity.
