Abstract

Roller bearing cage, especially for cylindrical roller bearings or needle bearings, which presses the rolling elements elastically in the radial direction against a raceway to prevent rippling, characterized in that, at least at one point (6), the cage (1) has notches (8) proceeding from the end surfaces (10) and a connecting part (11), which is rigid in the peripheral direction and which is located between the notches; and in that, in the peripheral direction, a recess (9), extending approximately across the width of the cage, is provided on one or both sides next to notches (8), this recess forming the boundaries of elastic sections (12).
