WQZ|WQZD self lubricated bushing solid inlaid self-lubricating bearings with the design of the belt, can limit the axial movement of the sleeve. This product is a kind of high performance solid lubricant which is inlaid with graphite and MoS2 solid lubricant on the base of copper alloy. It breaks through the limitation of oil film lubrication. In the process of using, the friction between the solid lubricant and the shaft is caused by the friction heat, and the excellent conditions for the coexistence of the oil and the powder are formed. It is more than twice the hardness of copper sets, wear resistance is also doubled. At present, it has been widely used in the field of metallurgical continuous casting machine, train support, steel rolling equipment, mining machinery, ship, gas turbine, etc.
