Properties

  • Design:
    • with a single radial clamping screw per hub ISO 4762
    • backlash-free, blind mate press-fit connection
  • Temperature range: -30° C to +110° C (-22° F to 230° F)
  • Tolerance: On the hub/shaft connection 0.01 to 0.05 mm.
  • Service life: These couplings have an infinite life and are maintenance- free if the technical ratings are not exceeded.
  • Material:
    • bellows made of highly flexible high-grade stainless steel
    • the clamping hubs and tapered female segment on the bellows face are aluminium
    • tapered segment on the hub face: glass-fiber reinforced plastic deposited onto an aluminium hub.
  • Speeds:
    • up to 10,000 rpm
    • over 10,000 rpm available with balanced version.
  • Non-standard application: Custom designs with varied tolerances, keyways, non-standard material and bellows are available upon request.
  • Properties of Miniature Coupling model MK5:
    • absolutely backlash-free and torsionally rigid
    • compensates for 3-axis of misalignment
    • easy mounting and dismounting
    • electrically insulated
    • no wear
    • low moment of inertia
