The invention discloses a device and method for measuring the radial run-out of a roller part based on synchronous belt drive. The device comprises two V-shaped supports, and the central part of the lower side of the roller part is provided with a synchronous belt drive device, and the upper side of the roller part is provided with an elastic compressing device. The lower side of the roller part is provided with a flexible gauge sensor, and a signal output end of the flexible gauge sensor is connected with a computer. The method comprises the steps: enabling two ends of the roller part to be respectively placed on the two support devices; starting the synchronous belt drive device to drive the roller part to rotate; driving the elastic compressing device to descend through an external pressing device, and pressing the roller part so that the roller part rotates stably; reading the maximum and minimum values of the flexible gauge sensor in one rotating circle of the roller part; and subtracting the minimum value from the maximum value to obtain the radial run-out of the roller part. The device and method are quick and automatic in measurement, is high in universality, and is high inmeasurement precision.
