Motion of a Ball in the Angular-contact Ball Bearing
Transactions of the Japan Society of Mechanical Engineers, 1964 The behaviour of a ball in a ball bearing was observed through flux change caused by a magnetized ball. An angular-contact ball bearing of the type 7307 B was used in the experiment. Under pure thrust load, the ball makes a complicated three-dimensional motion.

Investigation of ball vibrations in angular contact ball bearings
, 2020 In this study, a shaft-bearing model is developed in order to investigate ball vibrations in case of defected and undefected ball bearings. In this model, shaft-bearing couple is considered as a mass-spring system and balls are massless. It is well known that the behavior of the system has a nonlinear character under dynamic conditions.
