Experimental dataset on rolling contact fatigue life of bearing steel under semi-fluid grease lubrication conditions (EP0, EP00, EP000)

This dataset contains experimental results from Four-ball tribometer tests performed on AISI 52100 bearing steel balls to study rolling contact fatigue (RCF) and wear damage. The experiments were conducted according to the IP 300 standard, where a single rotating ball was loaded against three stationary balls under controlled conditions.本数据集包含针对AISI 52100轴承钢球开展的四球摩擦磨损试验机（Four-ball tribometer）试验所得实验结果，旨在研究滚动接触疲劳（RCF）与磨损损伤。本次实验严格遵循IP 300标准实施，试验过程中单个旋转钢球在受控工况下与三个静止钢球接触加载。
