Oil seal is used to seal oil (oil is the most common transmission liquid substances, it also refers to the general meaning of the liquid substance) and mechanical components, transmission components it needs to lubricate the parts with the parts contribute to isolation, and will not allow oil leakage. Static seal and dynamic seal (generally reciprocating motion) is called with seals seals. Representative form of TC oil seal oil seal, which is a completely coated with rubber springs from the lips tight seal, the general said, often means that tc oil seal oil seal.

Common seal materials: nitrile rubber, fluoro rubber, silicone rubber, acrylic rubber, polyurethane, PTFE, etc. Select the seal material, the material must consider the compatibility of the working fluid, the working temperature range of adaptability and lip of the rotation axis when the ability to follow high-speed rotation. Normal oil seal lip when working temperature is higher than its working medium temperature 20 ~ 50 ℃, the choice of seal materials should be noted. For details, please refer to: rubber types and characteristics. The scope of work and the oil seal oil seal materials used for: material NBR (NBR) when -40 ~ 120 ℃, Alec rubber (ACM) -30 ~ 180 ℃, fluorine rubber (FPM) -25 ~ 300 ℃.
