Abstract

A pocket cage for a rolling bearing, e.g. a cylindrical roller bearing, made in a mold with single-piece, radially movable sliders, in particular out of plastic material with low deformability, which cage comprises two side rings connected by webs, with at least the circumferential outer surface or the bore being provided with projections which project into the pockets and extend along only part of the web length for retaining the rolling elements in the radial direction. In particular, a retaining projection is provided on a first side of each web and a recess, i.e. free space, is provided on a second side of each web. The angle between the oblique surface of the recess and the second side surface of the web is greater than or equal to the angle between the surface of the retaining projection which faces the rolling element and the first side surface of the web.
