Plastic cage for friction bearings, designed with same inner diameter of rings, bridges, and spring elements in order to be economically molded

摘要

The journals are guided between the inner and outer ring (1, 2) and supported by hook-shaped spring elements (6, 7) permanently joined to a recess (5) provided in the bridges (3) in order to offer a space for the spring (6, 7) when it is moved. The rings (1, 2), bridges (3), and spring elements (6, 7) are all of the same inner diameter, facilitating the injection molding by using a simple cylindrically shaped core with a smooth outer surface.
