Square Brass Flange Bush
FZ Ventilator Brass Bronze Square Bore Flanged 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.
square brass flanged bushing is made of Cu663 bronze (brass) powder metallurgy.It is sintered by 12% - 18% oil to ensure self-lubricating during using.It is used for ventilator,fire damper with square bore with collar to fit square spindle of device.
