    1. Detailed information

    JDB-11 Graphite-impregnated aluminum-bronze solid lubrication bearings are customer-specified products. Its base is CuAl9Fe4Ni4Mn2 material. It's relatively ductile and corrosion-resistant. After graphite impregnation and oil soaking, it can be used without oil lubrication. This product has excellent mechanical properties, with good corrosion-resistance in atmosphere, water and sea water, high corrosion fatigue strength and good wear-resistance. JDB-11 is primarily used in moderate speed and load applications that require good corrosion-resistance, such as ship-building industries and harbor equipment.
