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.

Contact characteristics analysis of angular contact ball bearings with local defect
Vibroengineering Procedia, 2022 The contact angle and load distribution are important indicators for reflecting the operating condition of the angular contact ball bearing (ACBB). However, the raceway with local defect may cause serious diversification of contact angle and contact load.

Analysis of the Ball Load in Angular Contact Ball Bearings during Operations.
Journal of the Japan Society for Precision Engineering, 2001 Spindles used in machine tools, especially machining centers, must operate at high speeds with high stiffness and low temperature rise in order to achieve improvements in productivity and accuracy of the machine. Usually, preloaded angular contact ball bearings are used to satisfy these requirements.
