Rotary seal is used for high-speed and low-pressure rotary seal. It is applicable to circumstances when linear speed is less or equal to 40m/s, medium pressure is between 0.2mps and 3mpa, temperature is between - 60 ℃ and 180 ℃, situations with oil lubrication or dry friction without oil, and other working conditions that traditional oil seals cannot apply such as air pressure, engine, oil pump, oil motor, new energy power and other industries.
