Abstract
A process for producing a graphite cage for an anti-friction bearing, which cage holds a plurality of anti-friction elements, characterized in that a cage injection moulding is injected in an injection moulding process from a mass comprising carbon mesophase powder, and this cage injection moulding is subsequently heat-treated in order to transform the carbon from the mesophase into pure graphite.
Claims9
A process for producing a graphite cage, which holds a plurality of rolling elements, for a rolling bearing,
- wherein a cage injection molding 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.
