    1. Detailed information

    JDB-12 Graphite-impregnated aluminum-bronze solid lubrication bearings are customer-specified products. Its base is CuZn35Al2Mn2Fe1 material. Compared with JDB-12, it has moderate surface hardness and somewhat higher coefficient of friction. After graphite impregnation and oil soaking, it can be used without oil lubrication. This product has excellent mechanical and self-lubricating properties, with good corrosion-resistance in atmosphere, water and sea water, and easily machinable. JDB-12 is primarily used in moderate speed and load applications.
