Description of Silicon Nitride Bearing Balls

Silicon Nitride Bearing Ball is a man-made compound synthesized through several different chemical reaction methods. Parts are pressed and sintered by well-developed methods to produce a ceramic with a unique set of outstanding properties. Silicon Nitride Bearing Ball is ideal for bearing parts. Compared with steel, high-performance Silicon Nitride Bearing Balls have better mechanical properties under high temperature and could survive from most of the corrosive chemicals.
