Bearing steel grit is cracked from ball bearing scraps with heat treatments. This kind of steel grit has no cambered surface, efficiency higher than common cast steel grit for stone cutting. And also this bearing steel grit contain Chrome 0.6-1.6%, much more wear resisting during stone cutting . After heat treatment,it is featured with optimum mechanical characteristics, good tenacity,high fatigue resistance,long working-life,low consumption and so on. 30% will be saved.
