bearing materials 13 bearing materials 13.1 raceway and rolling element materials while the contact surfaces of a bearing s raceways and rolling elements are subjected to repeated heavy stress they still must maintain high precision and rotational accuracy to accomplish this the raceways and rolling elements must be made of a material that has high hardness is resistant to rolling fatigue is wear resistant and has good dimensional stability the most common cause of fatigue cracking in bearings is the inclusion of non-metallic impurities in the steel by using pure materials low in these non-metallic impurities the rolling fatigue life of the bearing is lengthened for all ntn bearings steel low in oxygen content and non-metallic impurities then refined by a vacuum degassing process as well as outside hearth smelting is used for bearings requiring especially high reliability and long life steels of even higher in purity such as vacuum smelted steel vim var cevm and electro-slag melted
