When selecting the material of the oil seal, the compatibility of the material to the working medium, the adaptability to the working temperature range and the ability of the lip edge to follow the rotation axis at high speed must be considered. Generally, the temperature of the lip edge of the oil seal is 20~50℃ higher than that of the working medium, so it should be noted when selecting the oil seal material. The working range of the oil seal is related to the material used in the oil seal: when the material is NBR, it is -40~120℃, Alec rubber (ACM) -30~180℃, fluorine rubber (FPM) -25~300℃.
