摘要:
In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.

Thin-walled bearing bushing produced in a drawing process for the support of pins in universal joints, consisting of a cylindrical sleeve section and a bottom section which closes this cylindrical sleeve section on one axial end whereby a peripheral rim with a small cross sectional radius is formed between the outside surface of the sleeve section and the outside surface of the bottom section, characterized in that a recess (9, 18, 22) is provided in one surface of the bottom section (6) radially inward of the peripheral rim (7) and axially impressed in said one surface.
