Metal-base inlaid solid self-lubricating bearings (abbreviated as JDB) is a novel lubricating bearing that combines the characteristics of metal bearings with the characteristics of self-lubricating bearings. The metal matrix bears the load and the specially formulated solid lubricating material acts as a lubricant. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is especially suitable for heavy-duty, low-speed, reciprocating or swinging devices that are difficult to lubricate and form oil film, and is not afraid of water leaching and other acid etching. And scouring. Users generally believe that inlaid bearings not only save fuel, save energy, but also have a longer life than ordinary plain bearings. The inlaid self-lubricating composite material is a new type of extreme pressure resistant solid lubricant material, which is composed of a metal substrate and a solid lubricant paste embedded in the hole or groove of the substrate. The metal substrate bears most of the load during the friction process. Through friction, the solid lubricant in the hole or groove is transferred to the friction surface, and a solid transfer film with good lubrication, firm adhesion, and uniform coverage is formed on the friction surface, which greatly reduces the friction and wear. With the progress of friction, the embedded solid lubricant is continuously supplied to the friction surface, ensuring good lubrication of the friction pair during long-term operation.
