The utility model relates to a ball bearing guide screw pair, particularly a dynamic friction torque measuring device for a ball bearing guide screw pair. The utility model is composed of a force cell, a dynamic friction torque measurer for a ball bearing guide screw pair, a microprocessor and an analog recording device. The utility model is characterized in that the force cell is composed of a rigid rod, a body, a piezoelectric element, etc. The force cell has high rigidity and sensitivity. The measuring device solves the conflict between the dynamic response and the sensibility of the dynamic friction torque measuring for the ball bearing guide screw pair, and realizes the continuous automatic measurement of the dynamic empty running friction torque for the ball bearing guide screw pair. The utility model is widely used for the dynamic friction torque measurement for various ball bearing guide screw pairs.
