The merit of the regulation method of strength stress of conveyor rollers of industrial furnaces lies in the fact that the extended ends of conveyor rollers are treated by vertical forces caused by the effect of the pressure liquid counteracting load effects of the conveyor roller by the charge. The device for application of this method, which consists of conveyor rollers being mounted in the main bearings, is characterized by the fact that the conveyor roller (3) is equipped with extended ends (5), (5'), which are mounted in the bearing bodies (7), (7'), which are vertically movable in the bearing frames (8), (8'), which are attached to the furnace frame (2) by the supporting structure (9), while the linear hydraulic motors (10), (10') are attached to the bearing frames (8), (8') and their piston rods (11), (11') are in contact with the bearing bodies (7), (7') either directly or by means of the coupling member (12).<IMAGE>
