In order to evaluate the severity of asperity interactions in rolling contact, the author introduced a new parameter 'asperity interacting frequency N_<af>'. N_<af> is defined by the number of contact positions of higher hardness roller with different microgeometries which are brought into contact with any one position of mating lower hardness roller and the effects on rolling fatigue have been examined using thermal refined or hardened rollers with different hardnesses. As the results, similar to the previous results obtained using normalized steel rollers, it was found that there exists a regular relation between the parameter N_<af> and the pitting life in pure rolling conditions. Furthermore, it was recognized that the occurrence of micro pitting, which is apt to develop on the surface of a case-hardened steel roller, is decisively affected by the parameter N_<af>.
