JDB-1 solid lubricant embedded bushing is a new type made from strong brass and homogeneously embedded with solid lubricant in its body. It breaks through the limit of general bearing whose lubrication depends on oil film. So it is suitable for high temperature, heavy duty, anti-corrosion, or where oil is hard to be introduced. It's performance doubles both on hardness and wear-friction.

CuZn25Al6Fe3Mn4
Material hardness：
210-250HB
Basically general-purpoducts, suitable for various circumatances including high or low temperature, with oil or oilless lubrication, or even in the water. With it's matrix made of high strength brass, It's hardness doubles than nirnal bronze bushings and the wear performance improves in large degree, so it is applicable for conticaster, pritching machine, converors of metallurgy industry. It could also be used in plastic injection machines, in the automatic switch of high=tension electricity, in the luffing and supporting parts of construction machines, hydraulic gate supporler, pilley, drive wheels of water control project, and dryung tunnel of paper machines, auto die sliding parts for ships unmooning etc.
| Solid lubricant | Cu | Sn |
|---|---|---|
| SL1 High purity graphite + additives | Good wear resistance and chemical stability, the use of temperature <400 ℃ | Used in general machinery, used in the atmosphere |
| SL4 PTFE + additives | Very low coefficient of friction and good moisture, the use of temperature <300 ℃ | Used in water, sea water lubrication, such as ships, hydraulic arc gate, turbine, pharmaceutical beverage machinery. |
