What is the material of the oil seal?
Oil seal material depends on what kind of oil seal, what is used, and so onGeneral material: Rubber (Ding Qingjiao, fluorine glue)Polyurethane (TPU, CPU)PTFE and so on
According to the use of the environment to determine material, such as the skeleton of carbon steel, stainless steel, fiber (also known as cloth, rubber), sealing lips are generally seen in NBR, NBR, FKM, fluorine rubber, SIL silicone rubber.
Now, the main material of oil seal is rubber, the heat resistance of rubber is good, and the price is cheap. Polyurethane also has polyurethane, mainly resistance to low temperature, friction resistance, weather resistance, good physical properties, and size is better control.
