    摘要: An outer ring 6a for a shell-type radial needle bearing having a cylindrical shape with a bottom is achieved for which fatigue life of the bottom plate section 9a and the continuous section between the bottom plate section 9a and the cylindrical section 8a is improved, as well as the anti-corrosion characteristic of the outer ring 6a is improved and the outer ring 6a can be prevented from coming out of the bearing without an increase in cost. After obtaining an intermediate raw material 35 having a cylindrical section and a bottom plate section from a metal raw material, shot peening is performed on the intermediate material 35 to create residual compressive stress in the surface and surface layer section on the outer surface side of the cylindrical section 8a and the bottom plate section 9a such that the residual compressive stress in the surface layer section on the outer surface side is greater than the in the surface layer section on the inner surface side, and from the surface to a depth of 0.03 mm is 700 MPa to 1600 MPa.

    摘要: A needle roller bearing comprises a plurality of needle rollers and a retainer. The retainer includes a pair of annular parts and pillar parts connecting the pair of annular parts so as to form pockets in which the needle rollers are housed. A sidewall surface of the pillar part has a sheared surface punched by a punching blade so that the pockets are formed, and a fractured surface fractured by a material pressed by the punching blade. The needle roller is guided by the sheared surface.

    摘要: A method of manufacturing a retainer for a roller bearing made of a metal plate and has a tubular main portion, pockets formed in the main portion intermittently concerning a circumferential direction and capable of retaining rollers rollably, and an outwardly oriented flange-like collar portion. An annular intermediate material is formed by die cutting the metal plate, and after a second intermediate material is formed by forming through holes in the intermediate material intermittently, a portion of the second intermediate material excluding a radially outer end portion is plastically deformed into a tubular shape. The portion plastically deformed tubular shape is formed as the main portion, a portion corresponding to the radially outer end portion of the second intermediate material is formed as the collar portion or a collar portion element for forming the collar portion, and portions corresponding to the through holes are formed as the pockets.
