Fan Motor Bronze Bearing Bushing
FZ Electrical Fan Motor Spherical Oil Sintered Bronze Bushing 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.
Fan motor spherical oil sintered bronze bearing is made of bronze powder metallurgy with oil impregnated.Normally them are in spherical shape with sleeve or cut or collar for different electrical fan motor design.
