The utility model provides a rotatory NULL device that bearing was used, include the frame and fix the workstation in the frame, be fixed with a pair of sharp module and a pair of linear guide on theworkstation, equal slidable mounting has sharp module measurement workbench on the straight line module, a linear guide goes up slidable mounting has hand dynamic testing volume workstation, form a plane of supporting bearing to be measured after the model adjustment according to bearing to be measured of straight line module measurement workbench and manual measurement workbench, still install atleast two the 2nd linear guide that are used for supporting the sensor on the workstation. This application is through this project implementation, can be directly rotates NULL to the bearing of large -scale size. The running accuracy of outer lane also can be measured to the inner circle that the bearing both can have been measured to instrument. Can follow the deviation from circular form of isolating the bearing ring t
