The first ribs are respectively and partially stacked on the second ribs so that each first curved groove is combined with one respective second curved groove to create a respective ball accommodation chamber. Thus, the ball cage can be commonly used for ball bearings lubricated with grease or oil gas to increase the convenience of use.
