Abstract:
A process for producing a graphite cage for an anti-friction bearing, which cage holds a plurality of anti-friction elements. A cage injection molding is injected in an injection molding process from a mass which contains carbon mesophase powder, and this cage injection molding is subsequently heat-treated in order to transform the carbon from the mesophase into pure graphite.
