JDB-2 inlaid bronze bushings, is 5-5-5 bronze matrix, embedded in graphite or MoS2 solid lubricant as a solid lubricant. Due to high power density than brass bronze 5-5-5 high, so in the case of low load high temperature, reflecting very wearable, has been used in fireplace doors, oven raceway, rubber machinery, light industrial machinery, machine tools and other industrial low-load, high-temperature, medium-speed applications.
