Abstract

The invention relates to a process for producing a rolling bearing cage, in particular for large rolling bearings, wherein a steel strip with openings for in each case one rolling body is provided and bent to form a ring, wherein, for thermal coating with a thermoplastic powder, the ring is then heated to a temperature above a minimum coating temperature, wherein the ring is then dipped into a fluidized bed comprising the thermoplastic powder, wherein, during the residence time of the ring in the fluidized bed, plastic powder adheres to the ring, melts and forms a continuous coating, and wherein the ring is removed from the fluidized bed after the coating. The invention also relates to an apparatus for carrying out the process.
