Properties

  • Design:
    • With a single ISO 4762 radial clamping screw per hub.
    • Self opening clamp system optional: Loosening the clamping screw applies force to the pin, which will force the clamp into the open position for easy mounting and dismounting.
  • Temperature range: -30° C to +100° C (-22° F to +212° F)
  • Backlash: Absolutely backlash-free due to frictional clamped connection.
  • Service life: These couplings have an infinite life and are maintenance-free if the technical ratings are not exceeded
  • Tolerance: On the hub/shaft connection 0.01 to 0.05 mm.
  • Material:
    • Bellows made of highly flexible high-grade
stainless steel.
    • Hub material see table
  • Speeds: Up to 10,000 rpm, in excess of 10,000 with
a finely balanced version.
  • Non-standard applications: Custom designs with varied tolerances, keyways, non-standard material,
bellows and ATEX designs are available upon request.
  • Properties of Bellows Coupling model BKL:
    • economically priced
    • low moment of inertia
    • easy to mount
  • Design: With a single radial clamping screw per hub ISO 4762.
  • Temperature range: -40° C to +200° C (-40° F to +392° F)
  • Backlash: Absolutely backlash-free.
  • Material:
    • Bellows are made of highly flexible high-grade stainless steel
    • Hubs are made of aluminium
  • Compensating of misalignment:
    • Lateral misalignment up to 0,2 mm.

    • Axial misalignment up to 1 mm.
    • Angular misalignment up to 2° degree.
  • Speeds: Up to 10,000 rpm, in excess of 10,000 rpm with balanced version.
  • Properties of Miniature Coupling model BKL:
    • backlash-free and torsionally rigid
    • compensates for 3-axis of misalignment
    • low cost
