Copper sleeve

steelbiaxial

Bi–Metallic shaft sleeve The product with steel as matrix sinters copper and tin alloy on the surface and is rolling bearing by being rolled. Standard gold-bearing material concludes:CuPb10Sn10、CuPb24Sn4、CuPb30、CuSn6Zn6Pb3、AiSn20Cu and so on. The change of internal surface chemical composition of alloy layer can meet the requirements of different bearing pressure, different temperature and different sliding speed. During the production, friction surface which design different structure of oil tank and oil hole can satisfy the order of different way of filling oil and can prevent the phenomenon of biting the shaft.
