PROBLEM TO BE SOLVED: To provide a shell-type roller bearing inexpensively manufacturable capable of preventing an edge load without performing crowning for a roller and. SOLUTION: This roller bearing is provided with a cylindrical shell-type outer race 1A and a plurality of rollers 2. As for the cross-sectional shape of the outer race 1A, the thickness of the center part in the axial direction is thicker than the thicknesses of both end parts. By internally fitting the outer race 1A into a mounting hole 14 of a cylindrical surface shape of a housing 13, a raceway surface 1Aa is formed into a crowning shape.
