JDB-9 Graphite-impregnated bronze solid lubrication bearings are customer-specified products. Its base is CuSn10Zn2 material. Compared with JDB-8, it has higher surface hardness but also higher coefficient of friction. After graphite impregnation, it can be used without oil lubrication. Compared with regular bronze bearings, it has better corrosion-resistance property.JDB-9 is primarily used in low load, high temperature, and moderate speed applications.
