To provide a bearing device capable of surely preventing tilting of an outer ring.
In this bearing device 10, the outer ring is divided into two of an upper and a lower outer rings 12 and 13, and an upper rolling body 16, which is arranged between the upper outer ring 12 and an upper inner ring 14, and an upper holder 18 and a lower rolling body 17, which is arranged between the lower outer ring 13 and a lower inner ring 15, and a lower holder 19 form a bearing 11. In this bearing device 10, the upper outer ring 12 corresponds to an end surface 23A of an upper work roll 23, and the lower outer ring 13 corresponds to an end surface 24A of a lower work roll 24, and the rolling bodies 16 and 17 are arranged in upper and lower opposite to each other so that the upper rolling body 16 corresponds to the end surface 23A of the upper work roll 23 and that the lower rolling body 17 corresponds to the end surface 24A of the lower work roll 24.
