Oil-bearing and self-lubricating bearings What is the difference?

Oil bearing The metal powder as the main raw material, powder metallurgy sintered body, which is inherently porous, but also in the manufacturing process can be more freely adjust the number of pores, size, shape and distribution of technical advantages. The sintered body was impregnated with 10% to 40% by volume of the lubricating oil, and was used in a self-lubricating state. During operation, the bearing temperature rises, because the oil expansion coefficient than the metal, and thus automatically enter the sliding surface to lubricate the bearing. Oil bearing plus oil can be used for a long time, often used in refueling inconvenient occasions.
Metal-base mosaic solid self-lubricating bearing is a kind of both metal bearing characteristics and characteristics of self-lubricating bearings of new lubricated bearings, the metal matrix to withstand load, special formula of solid lubricating material lubrication. It has the characteristics of high load-bearing capacity, impact resistance, high temperature resistance and self-lubricating ability. It is especially suitable for occasions such as heavy load, low speed, reciprocating or swinging, etc., and it is not afraid of the erosion of water and other acid. And erosion. Inlaid bearing is not only fuel-efficient, energy saving, and its working life than ordinary sliding bearings. At present products have been widely used in metallurgical caster, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
