Properties

  • Design: Hubs with DIN 916 radial set screw and integral dismounting groove.
  • Tempretaure range: -30° C to +110° C (-22° F to +230° F)
  • Tolerance: On the hub/shaft connection 0.01 to 0.08 mm.
  • Service life: These couplings have an infinite service life, and are maintenance free, if the technical ratings are not exceeded.
  • Material:
    • bellows are made of higly flexible high-grade stainless steel,
    • hubs from aluminium.
  • Speeds: Up to 20,000 rpm, in excess of 20,000 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 MK1:
    • backlash-free and torsionally rigid
    • compensates for 3-axis of misalignment
    • a mounting groove or flattening of the shaft is not required due to the integrated dismounting groove
    • low-cost design
    • low moment of inertia
