Bimetal bearing bush: the non-oil lubricated bearings in one, the product is of high quality low-carbon steel back as the substrate, or the surface of the sintered CuPb10Sn10 CuSn6Zn6Pb3 CuPb24Sn4 pewter or bronze alloy and QSn6.5-0.1, after several high temperature sintering and densification times and rolled copper, steel, one of the bimetal strip roll is made, the carrying capacity of the bearing alloy is one of the strongest, suitable for middle speed and high impact load bushings, thrust washers and other types of applications. the balance of the bridge bush heavy vehicles are using the product, is a widely used high load low speed bearings. At higher sliding property, lack of lubrication and water as the media have a particularly good self-lubricating properties of the medium, for dual metal casting materials, corrosion-resistant high-speed sliding bearings, and crushers, pumps, cold rolling mill bearings, negative Heda 70MPa piston pin sets the main widely used in heavy-duty vehicle axle balance bushings, gaskets, automobile steel bushing, the internal combustion engine main bearing, connecting rod bushings, rocker arm bushings, pump-side friction plates, small and medium-power Bearing the internal combustion engine, train engine bearings, bushings air press, refrigerator and so on. TFPSWB AISn20Cu, ZChSnSb7.5-3 Steel substrate, the surface roll AISn20Cu material products. The product has medium fatigue strength and load capacity, good corrosion resistance, good sliding properties and other characteristics. The product is commonly used for small and medium power internal combustion engine bearing, train engine bearings, bushings air finale machine, replace babbitt innovative products. Alloy layer Material: AISn20Cu Load capacity: 30N / mm2 Maximum operating temperature: 150 ℃ Alloy layer hardness: HB30 ~ 40
