The difference between Bearing

The sintered body produced by the powder metallurgy method, which is inherently porous, has the technical advantages of the number, size, shape and distribution of the pores that can be freely adjusted during the manufacturing process. The use of sintered body porous, so that impregnated with 10% to 40% (volume fraction) of lubricating oil, in the state of their own use. Operation, the bearing temperature increases, because the oil expansion coefficient than the metal, and thus automatically enter the sliding surface to lubricate the bearing. Oil-bearing bearings plus a single oil can be used for a long time, often used for refueling inconvenient occasions.
Metal-based inlaid solid self-lubricating bearing is a combination of metal bearing characteristics and self-lubricating bearing characteristics of the new lubricating bearings, from the metal matrix to withstand the load, the special formula of solid lubricating material from the lubrication. It has the characteristics of high carrying capacity, impact resistance, high temperature resistance and high self-lubricating ability. It is especially suitable for occasions such as heavy load, low speed, reciprocating or swinging and so difficult to lubricate and form oil film, and is not afraid of water erosion and other acid And scouring. Mosaic bearings are not only fuel-efficient, energy-saving, and its working life is longer than ordinary plain bearings. The current products have been widely used in metallurgical caster, rolling equipment, mining machinery, ships, steam turbines, turbines, injection molding machines and equipment production lines.
