FB090 bronze self-lubricating bearings use a specially formulated high-density copper alloy strip as the substrate, and the surface can be rolled with diamond-shaped or hemispherical oil holes and oil grooves according to user requirements. Various dvantages, such as high density, large bearing pressure, good wear resistance and long service life,for which can replace the traditional cast copper sleeve, which can reduce the mechanical volume and reduce the cost. FB090 has been widely used in lifting machinery, construction machinery, automobile, tractor industry, machine tool industry and mining machinery. It can be made into bearing bush, flange bushing, thrust washer and ball bowl.
