Abstract

An antifriction bearing cage is disclosed including cage pockets that are used for guiding rolling elements, in particular balls, and are formed by two lateral rings having a common axis of symmetry (R) and by webs interconnecting the lateral rings. The lateral rings are designed as single pieces along with the webs and contain a fabric. The fabric is composed of at least two types of different fibers which impart highly anisotropic properties to the fabric.
