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. And a properly engineered silicon nitride bearing ball fails in the same manner as a steel ball, flaking of the ball surface.
