    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
