During data collection, the integrated thermal-lubrication-dynamic analysis model was employed to perform full-field calculation and extraction of the force, thermal and lubrication states of each bearing component under various loads, rotational speeds and ambient temperatures. The dataset covers key characteristic quantities including intermediate results of static and dynamic loads, steady-state and transient temperature fields of nodes, friction power dissipation distribution, oil film thickness and friction coefficient, centrifugal force of rollers, contact power dissipation, forces and power dissipation of the cage, etc., which systematically reflects the multi-field coupling response characteristics of bearings under complex working conditions. With clear data structure and complete parameters, this dataset can provide important model verification and comparative reference for the analysis of thermal-mechanical coupling mechanism of rolling bearings, life prediction and research on lubrication failure under high-temperature working conditions.
