PROBLEM TO BE SOLVED: To provide a radial tapered roller bearing capable of using a plurality of radial tapered roller bearings while combining them in a state that spacers are not always disposed, and using the spacers of the same size in an inner ring and an outer ring in a case when the spacers are used, thus process efficiency and dimensional accuracy of the spacers can be improved, the number of components can be reduced, and adjustment of bearing clearance, and manufacturing management can be performed with high accuracy.SOLUTION: In a single row radial tapered roller bearing 1, axial widths of an inner ring 2 and an outer ring 3 are made equal to each other by disposing extending portions 2c, 3c so that end faces 2a, 3a and end faces 2b, 3b exist on the same plane orthogonal to the axial direction, at one end side and the other end side in the axial direction of the inner ring 2 and the outer ring 3. A radial tapered roller bearing set can be constituted by bringing the end faces 2b and the end faces 3b of the inner ring 2 and the outer ring 3 into closely contact with each other while opposed to each other without needing spacers. |
