JDB-650 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 performance doubles both on hardness and wear-

friction.  It  is now widely applied  in successive casting machines, steel rollers  in 

metallography, mineral machine, ships. steam  turbine. hydraulic  turbines and 

injection molding machines for plastics.
