Abstract

A pocket cage of synthetic material for roller bearings including a plurality of rollers spaced circumferentially, consisting of side rings and ribs arranged between them, whose pocket-side working faces are adapted to the roller shape, each rib having a first section arranged in the region of the arc separating the rollers in the circumferential direction of the bearing, and a second section holding the rollers in the radial direction of the bearing, characterized in that the pockets are widened at least in the region of a side ring by reduction of the holding sections.
