Spherical Sintered Bushing
FZ-S Sphercial Oil Sintered Bronze Bushing
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.It is easy to make the part to different shapes like cylinder,flanged,spherical,square,etc.
