PROBLEM TO BE SOLVED: To provide a bearing device capable of preventing the leakage of lubricant for a bearing to the outside by securing airtightness between the mating faces of a split type bearing device.SOLUTION: The bearing device includes: a cylindrical inner ring 1; and an upper housing 2 and a lower housing 3 which are opposed to each other and between which the inner ring 1 is held. The lower housing 3 is provided with a concave spherical circular groove and a semicircular outer ring 4 having a convex spherical outer peripheral face face-contactable with the circular groove. The bearing device further includes a plurality of rolling elements laid rotatable relative to one another between the inner ring 1 and each of the upper housing 2 and the semicircular outer ring 4. The opposed faces of the upper housing 2 and the lower housing 3 are integrated with each other in a face-contacting state. A seal 6 is provided between the mutual contact faces of the upper housing 2 and the lower housing 3. |
