<p>The invention relates to a window cage (1) for a needle bearing. The pockets (5) of said window cage are formed by punched out sections and by a stamping process with material displacement in a cage strip (9) which is then bent round. According to the invention, the window cage (1) is characterized in that before the cage strip (9) is bent, the opposite surfaces of the web walls of a pocket (5) are made up of three sub-surfaces (10, 11, 12) in the area of the retaining projections (7, 8). The first two sub-surfaces (10) follow a course which is parallel to a middle vertical (13) and each extend into a second sub-surface (11) at their upper end, said second sub-surface running diagonally in the direction of the central point of the pocket. Each of the second sub-surfaces then ends in a third sub-surface (12) which also runs parallel to the middle vertical (13).</p> |
