Self-lubricating bearings are divided into composite self-lubricating bearings, solid self-lubricating bearings embedded, bimetal self-lubricating bearings, self-lubricating bearings with special materials, according to different uses and mining, choose different self-lubricating bearings.
    It has a high load capacity, impact resistance, high temperature, self-lubricating ability and other characteristics, especially for heavy load, low speed, reciprocating or swinging difficult to lubricate and the formation of oil film occasions, are not afraid of water erosion and other acid erosion And wash. At present products have been widely used in metallurgical continuous casting machine, rolling just equipment, mining machinery, molds, lifting machinery, textile machinery, wind power generation, ships, steam turbines, turbines, injection molding machines and equipment production lines. Wear resistance is double the normal sleeve.
    In the friction process, the metal substrate bear most of the load. The friction, hole or groove of the solid lubricant to the friction surface transfer or reverse transfer, the friction surface to form a well-lubricated, solid adhesion and uniform coverage of the solid transfer film, greatly reducing the friction and wear. As the friction progresses, the embedded solid lubricant is continuously supplied to the friction surface to ensure good lubrication during long-term operation.
    One of the major categories of solid self-lubricating solid self-lubricating bearings (referred to as JDB) is a new both the characteristics of metal bearings and oil-lubricated bearings non-lubricated bearings, supported by the metal substrate load, a special formula of solid lubricating material lubrication. Inlaid self-lubricating composite material is a new type of anti-extreme pressure solid lubricating material composed of a metal substrate and a solid lubricant paste embedded in a hole or a groove of the substrate.
