The utility model proposes a solar two-dimensional tracking support and a bearing seat assembly therefor. The bearing seat assembly comprises a top seat and a bearing seat. The top seat is fixed at the upper end of a vertical column, and comprises a top plate, a plurality of side plates, and two lower hinge lugs. The top plate is located on the upper end face of the vertical column. The plurality of side plates are fixed on the lower surface of the top plate, and define an accommodation groove along with the top plate, so as to accommodate the upper end part of the vertical column. The two lower hinge lugs are fixed on the upper surface of the top plate at intervals. The bearing seat is hinged to the top seat through an axis pin. A main beam passes through the bearing seat. The extension direction of the axis pin is perpendicular to the extension direction of the main beam. The bearing seat assembly provided by the utility model does not need to be welded in a process of manufacture, thereby greatly reducing
