What material oil seal, high temperature and wear resistance?
The seal is used to seal oil (oil is the most common liquid substances, the transmission system also refers to the general liquid substance of Italy) mechanical element. It will need lubricating components and output component isolation in the transmission parts, so as not to let the oil leakage. Static seals and dynamic seals (general reciprocating motion) use seals as seals. Oil seal is the representative form of TC oil seal, which is a rubber fully coated with self tightening spring lips oil seal, generally speaking, oil seal often refers to this kind of TC skeleton oil seal
Fluorine rubber is the best heat resistance, fluorine rubber in a good period of vulcanization and two stages of vulcanization is certainly the most appropriate.. But now dozens of ordinary small fluorine rubber yuan Jin [200 degrees can also use simple] good, hundreds or even thousands of Yuan Jin [220-260] work at room temperature, the key to see your environment there is a need for better wood!
Commonly used oil seal materials are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, PTFE and so on. When choosing the material of the oil seal, it is necessary to consider the compatibility of the material to the working medium, the adaptability to the range of the operating temperature and the ability of the lip to follow the rotation of the rotating shaft at high speed. When the general oil seal works, the lip temperature is higher than the working medium temperature 20~50 degrees, and should be paid attention to when choosing the oil seal material.
