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.
