HTB-31 soIid lubricant embedded bushing is a new type made from strong brass and homogeneousIy 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 oiI 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, hydrauIic turbines and injection molding machines for plastics
