APPLIED RANGE :

Bearing steel is the general term for alloy steel used in the manufacture of bearing races and moving parts of all types of roller bearings. High carbon and chromium bearing steel is widely applied in the manufacture of pin rollers and sleeves on driving shaft used in auto components, construction machinery, combustion engines, electric locomotive, machine tools, tractors, steel rolling equipment, and drilling and exploration equipment for mining industry. Carburized bearing steel is mainly used in railway locomotives and wind turbines. The high-grade bearing steel products developed with proprietary technology have been highly appraised by six leading bearing manufacturers in the world.
