Keyless shaft coupling

Disc Pack Couplings

Flexsteel is a zero backlash coupling which uses a disc pack made of stainless steel as a drive element, torsionally stiff, but axially and angulary flexible, to compensate for shafts misalignments.

  • Basic shape, pilot bore or key hubs
  • Hubs with 2 or 3 parts Shrink Discs
  • Hubs with internal clamping elements
  • Clamping Hubs or Splitted Hubs
  • Low inertia aluminium clamping hubs

A sigle disc pack can compensate angular and axial misalignments.
Two disc packs can compensate for radial, angular and axial misalignments.

FLEXSTEEL: the advantages of the system

  • Zero backlash, and torsionally stiff
  • High torque density and low mass moment of inertia
  • High shaft misalignment compensation
  • High temperatures up to 240°C
  • High speeds
  • Long life, maintenance free
