The paper proposes a study of the thermal process in a radial self-lubricating polymer sliding bearing operating in a swinging motion mode. The thermal process in a sliding bearing is described by a three-dimensional heat conduction equation in cylindrical coordinates. The technique for determining the kinematic conditions is proposed on the basis of a numerical analysis of the temperature field in the contact zone of the shaft and the bearing, under which the mathematical model of the thermal process must take into account the speed of the shaft. The results obtained can be used in thermal diagnostics of friction in real sliding bearings.
