Properties

  • Design:
    • balanced clamping hubs with one radial screw per ISO 4762
    • intermediate tube section supported by gimbals within the clamping hub
    • mounting and dismounting accomplished through the removal of the intermediate tube section
  • Temperature range: -30° C to +120° C (-22° F to +212° F)
  • Blacklash: Absolutely backlash-free due to frictional clamp connection.
  • Service life: These couplings have an infinite life and are maintenance- free if the technical ratings are not exceeded.
  • Tolerance: Shaft/hub connection 0.01 to 0.05 mm.
  • Material:
    • bellows made of flexible high grade stainless steel.
    • aluminum intermediate tube section through size 200, size 300 and up steel; optional composite CFK tube.
    • clamping hubs through size 60 aluminum; size 150 and up steel.
  • Speeds: Depending on length A, please contact R+W
  • Properties of Line Shaft model ZA:
    • compensation for misalignment
    • backlash-free and torsionally rigid
    • able to span long distances
    • standard lengths up to 6 m (19.68 ft.)
    • intermediate tube removable for easy mounting
    • no intermediate bearing support required
