The mechanism of surface rolling contact fatigue in rolling bearings is investigated by means of dedicated experiments and numerical simulations of the damage progression. ROLLING CONTACT FATIGUE (RCF) is a typical failure mode in rolling bearings and similar types of machine components. The fundamental work in RCF is due to Lundberg and Palmgren [1], [2]. The Lundberg-Palmgren theory was mainly focused on subsurface rolling contact fatigue, and it relies entirely on ideally smooth Hertzian stress calculations. Surface rolling contact fatigue (SRCF) instead involves the area close to the surface of the contact (a few microns deep) that is strongly affected by local surface traction and stresses originated from geometrical features of the surface such as roughness, profile deviations, indentations, etc.
