Claim Text:
1. A roller bearing cage for mounting rollers around a circle in a bearing, said roller bearing cage comprising: two substantially semi-cylindrical halves of the cage cut from a cylindrical cage blank and re-assembled by connecting adjacent cut edges of each substantially semi-cylindrical half together, and a plurality of pockets for mounting said rollers in the cage, each of said rollers having a center axis, a shape of each of the plurality of pockets or their positions being provided so that the position of said rollers in the respective pockets are such as to compensate for the material removed in the a cutting step, whereby the center axes of the rollers mounted in the pockets are set out on a circle centered on the cage axis, and the pockets which are furthest from joints between the two substantially semi cylindrical halves of the cage are shaped such that radially innermost positions of the center axes of said rollers contained therein are further from an inner circumferential face of the cage than correspondingly radially innermost positions of the center axes for rollers in pockets which are closest to the joints between the two substantially semi-cylindrical halves of the cage.
