<p><P>PROBLEM TO BE SOLVED: To provide a roller bearing having no risk of damaging rollers even when the length of pocket surfaces of a machined cage is shorter than the length of the rollers. <P>SOLUTION: The roller bearing includes: an outer ring 1 having an outer ring raceway surface on the inner peripheral face; an inner ring 2 having an inner ring raceway surface on the outer peripheral face; the plurality of rollers 3 arranged rollably between the outer ring raceway surface and the inner ring raceway surface; and the open type machined cage 10 having an annular part 11 and a plurality of pillars 12 provided projectingly from an axial end face of the annular part 11, and holding the respective rollers 3 in a plurality of pockets 13 formed between the pocket surfaces 14 which are opposed side faces of the pillars adjoining in the circumferential direction. An inclined face 16 is provided from the pocket surface 14 to the axial end face 15 of the pillar 12 and the boundary between the side face of the pillar and the inclined face continues gently. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
