Bearing measuring device and system of X-ray generator

The present disclosure relates to a bearing measurement device and system for an anode of an X-ray generator, the bearing measurement device assessing the quality of a bearing by measuring a startingfriction torque and a friction torque of the bearing, the bearing measurement device comprising: a vacuum container for providing a vacuum measurement environment; the driving unit is provided with adriving shaft which is coupled with a bearing of an anode of the X-ray generator to be detected, and drives the bearing to rotate by outputting driving which has a first rotating speed and rotates along the axial direction; the load loading unit is arranged to apply an axial force to the bearing as a load; the sensing unit is arranged to sense the torque of the bearing under the driving of the driving unit and under the action of the load at the same time; and the processing unit is configured to collect torque data from the sensing unit and determine the starting friction torque and the dynamic friction torque of the
