Properties

FEATURES

  • very high torsional stiffness
  • single flex design
  • backlash free for reversing loads

MATERIAL

  • Disc pack: highly elastic spring steel
  • Hubs: high strength steel

DESIGN

  • Two precision machined conical clamping ring hubs mounted to the disc pack by means of high strength screws and bushings for alignment and frictional clamping of the assembly.
