<p>Provided are a bearing roller which can be formed with high accuracy and is capable of achieving a prolonged life, a processing method for a bearing roller, and a bearing which is capable of reducing rotational torque and enhancing rotational accuracy. Under a state in which the bearing roller is rotated about an axis of the bearing roller while being supported through intermediation of center holes (23, 24) in both end surfaces and held through intermediation of an outer diameter surface (20a), both the end surfaces (20b, 20c) and end-surface-side round portions (21b, 22b) at round portions (21, 22) are grinded. Further, under a state in which the bearing roller is rotated about the axis of the bearing roller by a driving force transmitted from at least one of both the end surfaces (20b, 20c) while being supported through intermediation of the center holes in both the end surfaces, the outer diameter surface (20a) and outer-diameter-surface-side corner portions (21a, 21b) at the round portions (21, 22) are grinded.</p> |
