The utility model discloses a rolling linear guide rail pair static stiffness measuring device. A servo motor is adopted to drive a trapezoidal lead screw to drive a loading nut to load a rolling linear guide rail pair, three loading modes of vertical loading, deflection loading and pitching loading can be performed for the guide rail pair by changing guide rail pair mounting positions and types of an upper guide rail clamp, and measuring points corresponding to different loading modes are distributed on the upper guide rail clamp and a lower guide rail clamp and used for measuring deformation and displacement of the guide rail pair during loading. The rolling linear guide rail pair static stiffness measuring device achieves automatic measurement of vertical static stiffness, deflection static stiffness and pitching static stiffness of the rolling linear guide rail pair, is large in load and high in measurement accuracy, and is capable of meeting requirements of different guide rail series on different loadin
