The invention relates to the technical field of elevators, in particular to a device and a method for measuring the running precision of a guide wheel or a diversion sheave of an elevator. The measuring method comprises the following steps: measuring the actual inclination amount of the end face of the outer ring of a bearing for bearing the guide wheel or the diversion sheave by using a pressure sensor and a spring; obtaining the maximum radial clearance value of the bearing; obtaining a maximum inclination amount based on the maximum radial clearance value; determining a rotation precision judgment value based on the planeness of the outer ring of the bearing, the allowable axial circle run-out of the end face of the outer ring of the bearing to the reference and the maximum inclination amount; and obtaining an actual rotation precision value based on the actual inclination amount, and comparing the actual rotation precision value with the rotation precision judgment value to confirm whether the rotation precision of the bearing is qualified or not. The measurement method and the measurement device provided by the invention can realize numeralization of rotation precision and effectively improve detection precision.
