The machinery industry is developing very rapidly.Nowadays, as the technology of our metal products becomes higher and higher, the mechanical properties will also be better.Don't look at small parts such as self-lubricating bearings.They play a very important role in large machinery.Plain bearings have the advantages of simple form, large contact area, stable and reliable operation, and no noise.Under liquid lubrication conditions, the sliding surface is separated from the lubricating oil without direct contact, which can greatly reduce the friction loss and wear of the surface.In addition, the oil film also has a certain vibration absorption ability.The disadvantage of plain bearings is that they cannot maintain sufficient lubricating oil reserves and have high starting frictional resistance.Self-lubricating bearings can drive the normal operation of large machinery.Without these products, our machinery would not work properly, so good maintenance can make our machinery last longer.
