Storage measuring device for an X-ray generator, characterized by the following:a vacuum vessel (108) to provide a measuring environment under vacuum;a drive unit (101) having a drive shaft coupled to a bearing to be measured (200) of an anode of an X-ray generator and rotating the bearing (200) by issuing an axial rotation motion with a first speed;a load unit (102) having a load output coupled to the bearing (200) and equipped to apply an axial force to the bearing during a load output measurement (200);a sensor unit (103) designed to measure the torque of the bearing generated by the drive unit (101) and simultaneously by the load (200); anda processing unit (104) designed to collect torque data from the sensor unit (103) and to determine from the torque data a starting torque and a rolling torque of the bearing (200) at the load and the first speed;where the stock (200) is installed in the vacuum vessel (108) during the measurement.
