ABSTRACT:
A plastic snap cage for ball bearings formed of an annular ring having a plurality of pockets each for receiving a ball therein uniformly spaced about the periphery thereof. Each of the pockets have an opening formed at one front edge of the ring limited by planar surfaces extending parallel and symmetrically to a radial line across the entire width of the wall cage thus defining the inside width of the pocket opening. Each of the pockets are also provided in the radial direction with a cylindrical first section conforming to the diameter of the ball and open towards the outer circumference of the cage, an adjacent conically tapering section forming bearing surface for the ball and adjacent to the latter a cylindrical, axially short third section. The entire pocket opening extends in depth in a radial plane open only to the first cylindrical section, up to its inside width.
