Bronze Sintered Bush
FZ Oil Sintered Bronze Bush Bearing
is made of bronze or
iron or stainless steel powder with lubricating oil vacuum sintered. It is mold
pressed by high pressure then sintered in high temperature, after that, put it
in high temperature vacuum and soaked in oil. This bearing is used in
electrical appliances, power tools, textiles machinery and automobile industry.
Like electrical fan, electrical motor, juicer, mixture, etc.
Oil sintered bronze bushing is made of bronze powder metallurgy.The part is full filled with mirco craves after sintering.Then the craves willed impregnated by 12% - 18% oil.
