Flanged shafts are used for torque transmission in the powertrain. On the one hand, they serve as a full floating axle shaft for driven rigid axles in commercial vehicles and, on the other hand, as a connection between the differential gear and the constant-velocity shaft in passenger cars. Process combinations are usually used to produce the flanged shafts. Firstly, the flange is generated by means of extrusion, then the shaft is elongated by swaging and, at the same time, the diameter is reduced. In this way, long undercuts are possible that would otherwise have to be produced by machining.

Production processes

  • Hot forging (swaging)
  • Warm forging
  • Soft machining
  • Gear manufacturing
  • Hard turning


  • Induction-hardening steels


  • Undercuts possible
