Abstract

A spacer for roller bodies, which are guided in a roller bearing and which have an axis of symmetry and have an axis of symmetry, defining a rolling axis, about which they roll in a revolution path of the roller bearing, includes two diametrically opposed, spaced-apart end parts, which are each located transversely to the direction of motion of the roller bodies and have contact faces for rolling faces of the roller bodies; two diametrically opposed, spaced-apart lateral parts, and each of the lateral parts connects the two end parts, has a platelike shape, with a flat side, extending transversely to the rolling axis of the roller bodies, for contact with the roller bodies, and short sides extending substantially in the direction of the rolling axis of the roller bodies, and is stiffened with regard to bending essentially orthogonally to the rolling axis of the roller bodies in such a way that in its motion along the revolution path, it essentially maintains its shape; and at least one rib, connecting the two lateral parts between the two end parts, which rib has contact faces for the rolling faces of two successive roller bodies.
