The method for manufacturing rolling bearing components such as cages and cage portions for deep groove ball bearings or angular contact ball bearings and loose guiding rings for spheric roller bearings by forming the material, which may be sheet metal or wire, to a spring formed unit, cutting a coil of the unit, joining the overlapping ends of the coil by welding, whereupon the joint is pressed to such an extent that the thickness of the material is uniform all around the unit and thereupon giving the unit the final shape in a press. |
