introduction：1.Frictional compatibility The property of preventing adhesion and boundary lubrication when the bearing diameter is in direct contact with the bearing bush。The material factors that affect the friction compatibility of friction pairs are： （1）The degree of difficulty in forming alloys in metallurgy。 （2）Affinity of material to lubricant。 （3）Friction factor of the auxiliary material in the non-lubricated state。 （4）Microstructure of materials。 （5）Thermal conductivity of the material。 （6）The size of the surface energy of the material and the characteristics of the oxide film。 2.embedability The material allows foreign hard particles in the lubricant to clamp in and prevent scratching or scratches

introduction： Whereas the oil seal is in an atmosphere and oil environment，Therefore, the oil resistance of the material is required、Good resistance to atmospheric aging；At the same time, it often encounters dust、Muddy water，And it has a very high speed，Therefore, it requires good wear resistance and heat resistance。In some special cases such as when oil seals are used to seal chemicals，It is required that the material should be adapted to the medium。 The rubber used for oil seals is mainly nitrile rubber、Acrylic rubber and polyurethane rubber，Silicone rubber is used in special cases、Fluororubber and polytetrafluoroethylene resin。Nitrile rubber has excellent oil resistance；The wear resistance of polyurethane rubber is outstanding；And silicone rubber is high resistant、Low temperature performance is very good；fluorine
