Is Self-lubricate bearing your best choice?
MarginalBearing is a professional self-lubricate bearing manufacuturer,offer the best solution before delivery the products to customers. Mariga leads you to know better about the metal -based mosaic solid self-lubricating.
Metal powder as the main raw material in Oil-bearing bearings , and the sintered body made by powder metallurgy is inherently porous,which has the technical advantages that the number, size, shape and distribution of pores can be adjusted more freely during the manufacturing process.
Using the porosity of the sintered body, it is impregnated with 10% to 40% (volume fraction) of lubricating oil and used in the state of self-supplying oil. During operation, the bearing temperature rises, and because the coefficient of expansion of oil is greater than that of metal, it automatically enters the sliding surface to lubricate the bearing. Oil-bearing bearings can be used for a long time after refueling, which is often used in situations where refueling is not convenient.
The metal-based mosaic solid self-lubricating bearing is a novel lubricating bearing that combines the characteristics of a metal bearing and a self-lubricating bearing. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is especially suitable for heavy load, low speed, reciprocating or swinging occasions where it is difficult to lubricate and form an oil film, and it is not afraid of water erosion and other acids And scouring. Inlaid bearings not only save fuel and save energy, but also have a longer working life than ordinary sliding bearings. At present, the products have been widely used in metallurgical continuous casting machines, steel rolling equipment, mining machinery, ships, steam turbines, hydraulic turbines, injection molding machines and equipment production lines.
