  • Apparatus for assembling roller bearings
    Patent number: 4175319
    Abstract: Roller bearings are assembled in a circumferential path with a bearing bushing by successively feeding roller bearings to an annular channel formed between a piston and an outer sleeve member. The roller bearings are accumulated in the annular channel until a predetermined number of roller bearings occupy the channel. An axial force is then simultaneously applied to each of the roller bearings accommodated within the annular channel to insert the accumulated roller bearings into a prepositioned bearing bushing. The plurality of roller bearings are fed to and supported in the annular channel in the direction of insertion into the bearing bushing.
