摘要： The roller bearing 10 comprises a plurality of substantially cylindrical-shaped rollers 15 which are respectively interposed between a concave-shaped race surface 12 formed on an outer race 11 and a concave-shaped race surfaces 14 formed on an inner race 13. Each of the rollers 15 is structured such that the central portion of the rolling surface thereof is formed by a first convex-shaped bus 17 which corresponds to the concave-shaped race surfaces 12 and 14, while the two end portions of the rolling surface thereof are respectively formed by second buses 16 which have a radius of curvature smaller than the radius of curvature of the first bus 17.
