    1. Detailed information

    JDB-10 Graphite-impregnated bronze solid lubrication bearings are customer-specified products. Its base is CuSn12 material. Compared with JDB-8, it has higher tin content which reduces coefficient of friction, but at relatively higher cost. After graphite impregnation, it can be used without oil lubrication. JDB-10 is primarily used in low load, relatively high temperature, and moderate speed applications, such as construction equipment, metallurgy equipment, paper-making industries, and transportation industries wherever oil lubrication is difficult to perform.
