JDB-3 is made of two kinds of material, steel back sintered with CuSn6Zn6Pb3 powder as a Lining, then solid lubricant is embedded evenly in it. It is of cost effective and higher crash strength comparing with JDB-2 type, its ends can even be welded with machine part and assemble together. It is suitable for metallurgy machine, construction machine and where oil is hard to be employed. Base material: Bronze+CuSn6Zn6Pb3.

The innerside material of products of JDB-3 series is the sane as that of the JDB-2 series, so they could function as well as the that of JDB-2 series, In additional, they have other aducantages such as saving material costs, improving compressive strength, and that they could be assembled by welding the bushing surface together with other matrix. They are suitable for parts which need not oil lubrication of construction machines, metallurgy machines and conveying machines.
| 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. |
