Abstract
A process and apparatus for forming a cage part, for a ball bearing, wherein the cage parts are annular with alternate flat portions and ball receiving recesses. The cage parts are formed by pressing the rings from cage material such as steel. The flat portions are formed with axially extending rivet pins or holes for receiving the rivet pins of another cage part, in order to enable fastening of the cage parts together. The rivet pins are formed by pressing operation at the time as forming the cage part, by the flowing of the material of the cage part into recesses in a die.
