1) Materials: chrome steel, AISI 52100, 100Cr6, SUJ-2
2) Diameters: 0.5mm - 50.8mm
3) Grades: G5-G100
4) Hardness : HRC62-65
5) Certificate: ISO9001:2008,ISO14001:2004,ISO/TS16949:2009
6) Features: AISI 52100 chrome steel ball, SUJ-2 bearing steel ball have excellent surface finish, considerable hardness and a high load carrying capacity, as well as excellent wear and deformation resistance. They are through hardened in order to achieve the maximum mechanical strength. After cold working its precision can reach one over ten thousand of a millimeter.
7) Applications: SUJ-2 bearing steel balls are normally used in precision ball bearings and many industrial applications. Just as high speed low noise bearings, bicycles, motorcycles, automobiles, slide rail, universal ball, bags, electronics industry. They can also be used to grind other mediums.
