As the first domestic manufacturer to introduce German URW-160 BAD DUBEN vertical type bearing ring cold rolling forming machinery, we have also imported many sets of RIWA-2 and URWA-1x horizontal cold rolling forming units. By using these equipments we have been able to reduce consumption of raw materials by 20%, and improve the metallurgical structure of bearings; thereby prolonging their life spans threefold.

With complete inspection and testing facilities, our advanced precision instruments include SO910-1, SO910-2, WTV-6 and BVT-1A vibration testers, type XWBT automatic balance recorders, FTSS S4C Taylor surf roughness profile testers and Talyrond 31 roundness instruments. These apparatus facilitate our technical improvement, also ensuring outstanding product performance.

We are expecting the chance to sever our customers at home and abroad. Customer is our focal point!
