Bearing Steel

                                           

Bearing steel is a general term for alloy steel used to manufacture various types of rolling bearing rings and rolling elements. The high carbon chromium bearing steel is widely used in the rollers and bushings on the transmission shafts of automobiles, construction machinery, internal combustion engine manufacturing, electric locomotives, machine tools, tractors, steel rolling equipment, drilling machinery, etc.

Also used in railway locomotives and wind power industries.

Our suppliers offering well accepted qualities by world largest bearing factories like Sweden SKF, Japan NSK, KOYO, NTN, American TIMKEN, German SCHAEFFLER (LUK/INA/FAG),  Taiwan Dongpei and main domestic bearing factories.
