ABSTRACT:
A cage for a rolling element bearing, comprising elastically deformable prongs, each pair of prongs defining a cage pocket in which a rolling element can be accommodated by snapping-in. The thickness dimension of each prong, perpendicular with respect to its surface facing the corresponding cage pocket, is gradually diminishing, in the direction towards the free end of the prong. Preferably, the thickness dimension of each prong is diminishing, in general, according to a parabolic function. Thereby, the highest possible retaining force for the rolling elements is obtained, and yet the strains in the prongs upon assembly of the rolling elements are as low as possible.
