Claim:
1. A method for producing a rolling bearing cage for a rolling bearing having at least one row of rolling bodies, comprising: forming, from a ring of solid metallic material, a ring-shaped main body having a plurality of openings disposed therein that are each configured to receive one rolling body, said forming being performed by at least one of a deformation, cutting, or material-removing process; heating the ring-shaped main body to a temperature above a predetermined minimum coating temperature required to permit the main body to be coated with a thermoplastic powder; resting said heated ring-shaped main body for a predetermined interval of time after heating to permit the elevated temperature of the main body to homogenize throughout said main body, wherein the elevated temperature at an end of the resting interval of time is still above the minimum required coating temperature; immersing the heated ring-shaped main body in a fluidized bed containing thermoplastic powder so as to cause the thermoplastic powder in contact with the main body to melt and adhere to the main body so as to form a continuous coating thereon, wherein the immersing occurs after the heated ring-shaped main body is rested for the predetermined interval of time; and removing the coated ring-shaped main body from the fluidized bed.
