JDB-650 inlaid solid lubricating bearings, a series of sliding bearings, is in high strength brass ({ZCuZn25Al6Fe3Mn4 Cu Al Mn Fe the main chemical composition of Ni Zn percentage were 60 ~ 66% and 5 ~ 7.5% and 2.5 ~ 5% and 2 ~ 4% and 0.2 ~ 0.5% ~ 28%. 22)} on the basis of a kind of high performance lubricating products with graphite or MoS2 solid lubricant. It breaks through the limitation of oil film lubrication. In the use process, through the friction heat so that the solid lubricant and shaft friction, form the excellent condition of oil, powder coexist lubrication, protect the shaft wear, and solid lubrication characteristics of eternity. It is more than twice the hardness of copper sets, wear resistance is also doubled. According to different purposes, can be made of high strength alloy steel, brass, bronze, cast iron, stainless steel as the base.
