Product Description

SF-2 SBoundary Lubricating Bushing

Product introduction

SF-2 boundary lubricating bushing is based on a composite material with 3 firmly bonded layers:steel as backing,sintered bronze sphericalpower as interlayer and modified POM as lining layer,It fits well for low speed,middle-load and normal temperature and saves cost and prolings working life when replacing normal all copper sleeves.It is widely applied in auto chassis,forging machine,matallurgical and mining machine,civil engineering,power station,strip rolling industries,etc.
