Ball bearing, which necessarily must bear a high load on a narrow surface area, expose consequently themselves to a high contact pressure. Design engineers, therefore, have to have through knowledge of the effective factors by which the endurance life is strictly limitted on the ground that they may ensure the secure performance in such condition. The ball motion of the ball bearing is much complicated comparing with the other types bearing such as a roller bearing because of being with a certain contact angle on contact points between both surfaces and also with three dimensional rotation between a ball and a ball surface. Angular contact ball bearing on which the present paper will report the research results has much more difficult aspects to analyze experimentally and theoretically for its structural properties. As friction and lubrication conditions in an angular contact ball bearing are ones of the most important terms among such factors, the authors have carried out an experiment on practical loading condition that inner race is subject to a load and outer race to rotation. As the results the authors could make clear the effect of the lubricating condition in such operating system on the sliding and the spin angular motion between both contact areas.
