We Checked by Out Source With latest version of Metallurgical Microscope for checking the microstructure of bearing components. We maintain consistent quality of micro structure as per NABL Lab standard norms, in prime raw material as well as in heat treated rings with reference to STAHL-EISEN-PRÜFBLATT 1520, (SEP-1520) German chart, for following :
The grade of steel used is SAE-52100 / 100 Cr 6 (modified) bearing steel of international acceptability.
Bearing steel is used only after ensuring macro (for non metallic inclusion rating / cleanliness) and microstructure, as per standard specifications to ensure the long life of bearings.
