In a radial roller bearing having an outer race and rollers, the outer race has a cylindrical portion and first and second flanges extending radially inward from opposite axial ends of the cylindrical portion. Hardness or strength of the cylindrical portion in a vicinity of the first flange is higher than that in a vicinity of the second flange. A shape of the first flange is different from that of the second flange. When the radial roller bearing is assembled to hold a rotating shaft on which a radial load acts, the outer race is easily oriented in an axial direction of the rotating shaft based on the shape difference between the first and second flanges so that the cylindrical portion in the vicinity of the first flange receives higher bearing pressure due to the radial load. Accordingly, flaking or peeling is unlikely to occur so that life time endurance and strength of the radial roller bearing is improved.
A radial roller bearing comprising:
A rotating apparatus having a rotating shaft and a pair of radial roller bearings for rotatably holding the rotating shaft, radial load acting on the rotating shaft between the pair of radial roller bearings, each of the radial roller bearings comprising:
