For details, please refer to rubber type and characteristics. The working range of oil seal is related to the materials used for oil seal: -40~120℃ for nitrile rubber (NBR), -30~180℃ for Alec rubber (ACM), and -25~300℃ for fluororubber (FPM).

 

Oil seal is used to seal oil (oil is the most common liquid matter in the transmission system, also refers to the general meaning of liquid matter) mechanical components, it will drive components in the need of lubrication and output components isolation, not to let the oil leakage.

The representative form of oil seal is TC oil seal, which is a rubber fully covered double lip oil seal with self-tightening spring, commonly referred to as the oil seal often refers to the TC skeleton oil seal.
