The commonly used materials for oil seals include nitrile rubber, fluororubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material for oil seals, it is necessary to consider the compatibility of the material with the working medium, adaptability to the working temperature range, and the ability of the lip to follow the high-speed rotation of the rotating shaft. The temperature of the lip of a general oil seal during operation is 20-50 ºC higher than the temperature of the working medium, and attention should be paid when selecting oil seal materials. For details, please refer to: Types and characteristics of rubber. The working range of oil seals is related to the materials used: -40~120 ºC for nitrile rubber (NBR), -30~180 ºC for acrylic rubber (ACM), and -25~300 ºC for fluororubber (FPM).
