A complex analytical model to evaluate the friction torque in a small thrust ball bearing with three balls mounted in a standard steel cage in the presence of the lubricant and loaded with a very low axial force. Was evaluated experimentally the differences between total friction torques for the thrust ball bearing with three balls mounted in cage and total friction torques for the same thrust ball bearing with three balls but without cage. The differences in total friction torques for rotational speed between 60 and 240 rpm were correlated with the analytical model. Has been evidenced that for very low loads the frictions between cage and balls have important contribution to the total friction torque and quantitative results were obtained.
