Indents in roller bearings perturb the pressure and stress distribution and increase the failure risk. A numerical study of the pressure perturbation is proposed. An existing dry contact model is extended to account for the indent shoulder influence and the pressure collapse in deeper indents. Moreover, results on pure-rolling lubricated contacts are presented. Finally, the ellipticity influence is studied both for dry and lubricated contacts.
