ABSTRACT OF THE DISCLOSURE In a process for measuring axle bearing temperatures in order to locate hot wheels in moving railroad cars, with infrared receivers, and with an oscillating scanning beam (1) that is oriented transversely to the longitudinal direction of the rail, the analogue measured values from the infrared receiver (7) are digitized and then coupled with the oscillation frequency orientation of the scanning beam, in which collection at least two complete oscillations of the scanning beam (1) are analyzed for each axle, a mean value being formed from the measured value corresponding to one sub area of a first oscillation of the scanning beam (1) and from the measured value (7) that correspond to the subsequent oscillation of the scanning beam (1) that correspond to the sub area of the subsequent oscillations of the scanning beam (1). When this is done, the formation of the average or mean value is repeated for a specific predetermined maximum number of oscillations of the scanning beam (1) and/or as long as a signal that is initiated by the wheel signals that the same axle is within the measuring angle of the center (7), and each instance the highest mean value of the measured values of corresponding sub areas is evaluated.
