Material Selection for Piston Rings Under High-Pressure and High-Speed Operating Conditions
Under high-pressure and high-speed operating conditions, piston rings endure extremely severe mechanical stress and thermal loads. High pressure generates significant backpressure behind the ring, drastically increasing the normal force between the ring and the cylinder wall. Meanwhile, high-spe...Read more -
PTFE Oil Seals: A Sealing Solution for High-Temperature, High-Speed, and Demanding Applications
In industrial equipment operating under high temperatures, high speeds, aggressive media, or low-friction requirements, conventional rubber oil seals may be limited by their temperature resistance, chemical compatibility, and friction characteristics. PTFE oil seals offer excellent temperature r...Read more -
