For example, most of the existing wheel hub bearing press-fitting devices can only press-fit on one side of the wheel hub, which is not convenient for pressing both sides of the bearing at the same time. Manual turning over is required, and the operation is relatively cumbersome, which leads to certain usage defects. Therefore, we propose a wheel hub bearing press-fitting device to solve the above problems. Utility Model Content
