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.
But ZrO2, Al2O3 and SiC fail in a crush form,a catastrophic failure.
