The Characteristic of Ceramic Balls
Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance,
high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These
properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and
decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
Ceramic materials, which can be used in making bearings, include mainly silicon nitride, ZrO2, alumina (Al2O3), and silicon carbide .
Si3N4 is first choice within the above mentioned ceramic materials due to its excellent characters (Table 1). And a properly engineered
silicon nitride bearing ball fails in the same manner as a steel ball, flaking of the ball surface. But ZrO2, Al2O3 and SiC fail in a crush form,
a catastrophic failure.
