[Application Features] JF800 bimetal bearings, low carbon steel plate as base material, the surface of the sintered steel or copper alloy products CuPb10Sn10 CuSn6Zn6Pb3 materials. The product is double alloy bearing a carrying capacity of the strongest heavy vehicle balance bridge bushings, gaskets; driven wheel dozer; automotive steel bushings are using the product. [Application] bimetal bearings it is a very versatile high-load low speed bearings. The main parameters of the alloy layer material: CuPb10Sn10 or CuSn6Zn6Pb3 Load capacity: 65N / mm2 maximum operating temperature: 260 ℃ alloy layer Hardness: HB70 ~ 100 Note: seamless welding technology, is the protection of the welding process, the welding area level . Usually we say arc welding, the arc is his exposed to air, the seamless welding commonly used as a protective layer of inert gas, it will be an arc, the molten pool and the base material are placed in a high temperature state of the protective gas inside, so called seamless welding. According to this sense, his prospects certainly better than the traditional ordinary arc welding, and with the progress of protection, the future will be more extensive meaning seamless welding.
