The ball bearing is being used widely as a crucial part of mechanic system. This research focus on the ball bearing particularly used in laser operating system for medical uses. We carried out examination to identified the potential of failure and theoretical rated life of the ball bearing by appropriate test method. Proper distribution and parameters were analyzed by software named the ALTA 6++. From these results the test method of accelerated life test for guarantee the theoretical rated life was evaluated and suggested.
