Product Description

Bronze bushing, It is made of bronze,mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the homogeneously spread tiny pores of the metal under vaccum.

It can be widely applied in continuous casting machines, mining machine, excavator,ships, air turbine, hydraulic turbines and plastic injection molding machines.


solid lubricant embedded bushing is made of casting bronze with graphite embedded evenly in it. It has superior performance than normal bearing whose lubrication depends on oil film. Under condition of heavy duty, high temperature, slow speed, anti-corrosion or Where oil is hard to be introduced, Its performance doubles both in hardness and anti-friction It can be widely applied in continuous casting machines, mining machine, ships, air turbine, Hydraulic turbines and plastic injection molding machines.
