Oil Sintered Iron Bearing
FZ-I PM Oil Sintered Iron Bushing 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 iron bushing is made of iron powder metallurgy.It is impregnated by 12% - 18% oil to ensure self-lubricating during using. The bushing shape can be in sleeve,flange,spherical,square,washer,and other customized.
