Solid contamination of lubricants is one of the main causes of premature rolling contact fatigue of machine elements (e. g. rolling element bearings in automotive gearboxes). Understanding the indentation process (creation of surface defect by debris passing through the contact) and the surface damage initiation allows the prediction of the induced risk. This article summarizes the work of the authors and proposes a risk prediction on the basis of operating conditions and dent geometry.
