Self-lubricating bearings, special materials self-lubricating bearings, according to different purposes and industrial and mining, choose different self-lubricating bearings, one of the large-scale solid inlaid self-lubricating bearings (referred to as JDB) is a combination of metal bearing characteristics and oil-free lubrication bearing characteristics The novel lubricated bearing is loaded by a metal substrate and the specially formulated solid lubricating material acts as a lubricant. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. It is especially suitable for heavy load, low speed, reciprocating or swinging, etc., which is difficult to lubricate and form oil film. It is also not afraid of water and other acid etching. And scouring. At present, the products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, molds, lifting machinery, textile machinery, wind power generation, ships, steam turbines, hydraulic turbines, injection molding machines and equipment production lines. Wear resistance is double that of ordinary bushings.

The sintered body prepared by powder metallurgy using metal powder as a main raw material is inherently porous, and has technical advantages such as the number, size, shape and distribution of pores which can be freely adjusted during the manufacturing process. The porous body of the sintered body is impregnated with 10% to 40% by volume of the lubricating oil, and is used in a self-supplying state. During operation, the bearing temperature rises, and since the oil has a larger expansion coefficient than the metal, it automatically enters the sliding surface to lubricate the bearing. Oil-bearing bearings can be used for a long time with oil, which is often used in places where refueling is not convenient. This kind of bearing was invented in the early 20th century. Because of its low manufacturing cost and convenient use, it has been widely used. Now it has become the basic parts for the development of various industrial products such as automobiles, home appliances, audio equipment, office equipment, agricultural machinery and precision machinery.
