ROLLING BEARING AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2011/145693

A1

Provided is a rolling bearing capable of stabilizing and retaining rolling elements and reducing production cost, while being excellent in strength, stiffness, thermal resistance, and dimensional accuracy without sacrificing performance as a bearing. Also provided is a method for producing the same. The rolling bearing uses a retainer that has a plurality of pockets that accommodate and retain said rolling elements in the circumferential direction of the peripheral wall of a cylinder-shaped member and which are separated by prescribed intervals, wherein said retainer is integrally formed by metal powder injection molding, and is provided with a rolling element-accommodating area. A structure for preventing the rolling elements from falling out is formed by compressing the outer periphery of the rolling element-accommodating area in the direction from the outer surface of said retainer toward the radial center.
