Abstract: With the development of the aerospace equipment manufacturing industry in China, higher requirements for accuracy, life and reliability of rolling bearings are put forward. The dynamic performance of high-speed rolling bearings, especially stability of the cage, has attracted more and more attention. Torque fluctuation and cage breakage caused by instability of the cage is one of the major failures of high-speed rolling bearings. In this paper, the dynamic characteristics and experimental research progress of the cage, factors affecting cage stability, stability criteria and optimization criteria of the cage are systematically summarized. The weaknesses of existing studies are discussed, and some orientations for future research are provided, such as the mechanism of stable cage whirl, the friction and wear characteristics of the contact pair under starved conditions, effects of change of lubrication parameters caused by lubricant loss and degradation, and effects of change of geometrical parameters of bearing parts caused by wear on dynamic performance of the cage. How to develop efficient and reliable software for dynamic analysis of the rolling bearing and how to combine the software with product design and life test have become urgent tasks for manufacturing of high-efficiency rolling bearings.
