The invention relates to a self-stabilization movable base for bearing machining. The self-stabilization movable base for the bearing machining comprises a base plate and an installation support plate. The upper end face of the installation support plate is symmetrically provided with four first hydraulic cylinders. The top ends of the four first hydraulic cylinders are provided with four first flanges in a threaded manner. The top ends of the four first flanges are installed in the middle of the lower end face of the base plate through screws. The first flanges have the function of connecting the first hydraulic cylinders and the base plate. Because the four first hydraulic cylinders are evenly distributed at the lower end of the base plate, the four first hydraulic cylinders exert uniform hydraulic bearing force on the base plate, the four first hydraulic cylinders drive the base plate to conduct stable height adjustment movement, and the self-stabilization movable base bearing machining achieves the stable height adjusting function. The lower end face of the installation support plate is symmetrically provided with four walking mechanisms through bolts, and the upper ends of the four walking mechanisms are provided with four telescopic rods correspondingly. The self-stabilization movable base for bearing machining can achieve the self-stabilization movable machining function on bearings.
