PROBLEM TO BE SOLVED: To provide a bearing suppressing the deterioration of reliability about stiffness, torque, a life by suppressing deformation due to fastening, when members on an outer peripheral side and an inner peripheral side are attached to an object in an axial direction by a bolt.SOLUTION: A bearing 1 includes: an outer ring 10; an inner ring 20; and rollers 40 arranged in two or more rows of track spaces 30 formed between the outer ring 10 and the inner ring 20. Bolt holes 15 and 25 formed on the outer ring 10 and the inner ring 20 satisfy an expression L1≤L2, when assuming a distance from counterbore surfaces 18 and 28 to installing surfaces 10T and 20T with objects W1 and W2 as L1, and a distance from a center of the roller 40 arranged closest to the installing surfaces to the installing surfaces 10T and 20T as L2. |
