A calibration method for the sphere center distance of standard multi-ball bar was proposed. According to the calibration method, the evaluation model of measurement uncertainty was established, and the sources of uncertainty were analyzed. The expanded uncertainty is less than one third of the nominal error, which verifies the feasibility and effectiveness of the calibration method
