The thermal resistance of an angular contact ball bearing as a function of the radial and axial load is investigated numerically. An elastic stress analysis, based on Hertzian contact theory, provides circumferentially-varying contact areas for input to the thermal model. A finite difference model of the combined conductive, convective and radiative transport from the inner to outer race is used to calculate the overall thermal resistance of the bearing.
