Abstract

A cage for a linear or rotationally guided rolling bearing has two uniformly spaced apart smooth boundary surfaces extending in the rolling direction, the cage having pockets adjacent one another in the rolling direction for receiving at least one rolling body. Each pocket has at least one recess pressed in the immediate vicinity of at least one edge in the opposed surfaces of the cage for the production of a holding groove. The walls of the holding groove closely surround dimensionally decreasing sections of the rolling bodies. Each holding groove is formed on the end of one or more holding tongues extending into the pockets. The recesses of the boundary surfaces are in the form of grooves with constant cross section, are pressed only in the holding tongues, and extend across the entire width of the holding tongues.
