CERBEC Professional balls are made from two types of silicon nitrides made by Saint-Gobain Ceramics: NBD200 and SN101C. Both are qualified by industrial bearing companies worldwide and meet all the essential requirements of a bearing grade silicon nitride. They are both fabricated using glass encapsulation HIPing which assures 100% density, high beta phase content, micron-sized grains, and minimal levels of glass phase. The attached TABLE 1 shows the typical properties for NBD200 and SN101C silicon nitrides.
