  • Apparatus and method for providing pockets in a roller cage of a bearing assembly and a roller cage produced by such an apparatus and method
    Patent number: 5899131
    Abstract: An apparatus for punching out pockets in a roller cage for rollers is provided with two simultaneously movable male dies whose outer cutting edges in the circumferential direction are spaced apart from one another by at least about 0.4 times the cage diameter. These male dies are preferably operative from the interior of the cage and each punches slightly more than half the pocket width. By indexing the cage by one pocket division each time, the pockets are punched out completely. In each punching increment, they receive the runup face for the roller over their entire length, which runup face need not be further machined.
