An analytical solution to compute the 3D steady state temperature distribution in a
bearing ring is presented in this paper. The ring is formed by a hollow cylinder of finite
length. Its radial external surface is subjected to localized, identical heat sources,
equally spaced in the azimuth direction. This surface is also subjected to convective
cooling while as the internal surface is maintained at a uniform temperature. The
developed solution is explicit and does not impose any restriction on the geometrical or
physical parameters.
