The invention relates to a device for measuring the temperatures of axles or bearings for locating hot-boxes or overheated brakes in rolling stock. The infrared rays of the measuring points are guided over an oscillating mirror (9) and onto an infrared receiver (8). Sent infrared rays are detected in th e scanning level which is defined by the oscillation of the oscillating mirror (9) and crosswise in relation to the longitudinal direction of the rails. At least two deviation mirrors (1, 2) are arranged in the scanning level and at a distance (a) from each other crosswise in relation to the longitudinal direction of the rails. The deviated infrared rays of the deviation mirrors (1, 2) are detected in chronological sequence and according to the oscillati on of the oscillating mirror (9).
