A motion guide device includes a ball nut attached onto a shaft and having helical grooves for receiving a number of ball bearing elements, and having a compartment form receiving a temperature detecting device which detects a temperature of the ball nut for preventing the ball nut from overheating, an indicating device is coupled to the temperature detecting device for generating an indicating signal when the temperature detecting device has sensed or detected that the temperature of the ball nut or the screw shaft is higher than the predetermined temperature or value, and the user may then stop working to find out what problems have been happened and thus to prevent the motion guide device from overheating.
