Self-lubricating plain bearings category and classification

     Bearings are "general equipment manufacturing industry" categories, "the manufacture of bearings, gears, gearing and driving elements" in the class, "bearing manufacturing" subcategories, it is part of the bearing axis, known as the "joint machinery", modern machinery and equipment indispensable basic components. The main function is to support the rotary shaft bearings or other moving body, rotate or move the guide movement and is received by the shaft or axis parts transfer from the load, as long as there is movement of the bearing joints. Rolling bearings and plain bearings can be divided into two categories; occurs when the rolling bearing is rolling friction work occurs when the work is bearing sliding friction between the surface and the surface; these are two different movement; at home and abroad Rolling materials and manufacturing techniques have been very mature, while sliding bearing materials and manufacturing technology along with the continuous improvement of the design and use requirements are gradually innovation development. The role is to play the slide bearing support shaft running to open to protect the role of the shaft and housing and bearing interval, which is an important function is to reduce the coefficient of friction and wear; sliding bearing according to the material and the performance can be divided into self lubricating sliding bearings and general plain bearings, self-lubricating plain bearings in the work process can be achieved without refueling refueling or less, and the general slide bearing itself does not have so good lubrication during operation must refuel; self-lubricating plain bearings can generally be divided three categories:
1, oil bearing, comprising a porous metal, wood and polymer materials, oil bearing; flying special oil-bearing FU series bearings.
2, dry friction bearings, no oil of its own, the work process and without refueling or other fluid lubricant. It includes some plastic bearings, and inorganic materials such as metal matrix composites made; flying special SF-1, SF-2, JDB-1 bearing.
3, special bearings, including rubber bearings, air bearings and magnetic bearings. Such as FD-AL bearings.
