Process for producing a graphite cage for an anti-friction bearing, which cage holds a plurality of anti-friction elements

摘要

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.

1. A process for producing a graphite cage, which holds a plurality of rolling elements, for a rolling bearing,
wherein a cage injection molding in a shape of the graphite cage that holds a plurality of rolling elements is injected in an injection molding process from a mass which contains carbon mesophase powder, and the cage injection molding is subsequently subjected to heat treatment in order to convert carbon from mesophase to pure graphite to produce the graphite cage that holds a plurality of rolling elements.
