PROBLEM TO BE SOLVED: To provide an automatic aligning roller bearing which achieves sufficient lubricity on an inside diameter face of a cage. SOLUTION: The automatic aligning roller bearing composed of two rows of rollers held by the cage 4 and a floating ring 5 between an inner ring 1, and an outer ring 2 is provided with an oil groove 7 for holding lubricating oil on the inside diameter face of the cage 4 opposing to the floating ring 5. Thus, since the lubricating oil collected in the oil groove 7 is not scattered outward in the radial direction even when large centrifugal force is applied on the cage 4 due to high speed rotation, sufficient lubricity is achieved on the inside diameter face of the cage 4.
