JDB-10 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. Its performance doubles both on hardness and wear-friction.

Base material ZCuZn25Al6Fe3Mn3
Material hardness 210-250HB
Maximum temperature 300°C
Max Load Capacity P 100N/mm²
Coefficient of friction u <0.16





Solid Lubricant

Solid lubricant Cu Sn
SL1 High purity graphite + additives Good wear resistance and chemical stability, the use of temperature <400°C Used in general machinery, used in the atmosphere
SL4 PTFE + additivesl Very low coefficient of friction and good moisture, the use of temperature <300°C Used in water, sea water lubrication, such as ships, hydraulic arc gate, turbine, pharmaceutical beverage machinery.
