Steel and copper inlaid bearings, steel sleeve in the base body, the overall sintered copper powder after the solid lubricant embedded solid lubricant products, except with the RCB-650's features, but also save costs and increase the compressive strength. End bearing copper inlaid steel with welded base installation, so for metallurgical machinery, construction machinery and oil field machinery medium can not refuel. (We can work according to requirements and different conditions and different use of sintered copper powder layers occasions
