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： The invention concerns a rolling bearing with a rolling bearing cage (1) having a plurality of rolling element pockets (2) arranged in at least one row to receive at least one row of rolling elements, wherein the rolling bearing cage (1) consists of two lateral rings (3) and a plurality of crosspieces (4) connecting them, between which crosspieces are formed the rolling element pockets (2), and having at least one empty pocket (5). In order to achieve cost-effective manufacture of the rolling bearing cage (1) with the fewest possible changes as compared to a rolling bearing cage fully populated with rolling elements, provision is made according to the invention that the rolling bearing cage (1) is equipped with fewer rolling elements in one row than corresponds to the number of rolling element pockets (2), causing the rolling bearing cage (1) to have empty pockets (5) without rolling elements in the at least one row of rolling element pockets (2). The empty pockets (5) can be implemented in a simple manner by omitting one or more rolling elements, so that storage spaces for lubricant are created. Furthermore, the empty pockets (5) can be formed by targeted shaping in such a manner that a conveying or pumping action is produced in at least one direction of rotation. The invention also concerns a method for producing such a rolling bearing cage.
