Properties

  • Design: Two couplings hubs concentrically molded with concave driving jaws. Bore tolerance H7 + keyway + clamping set screw.
  • Temperautre range: -20° to +100 °C (-4° F to +212° F)
  • Tolerance: On the hub/shaft connection max. 0.1 mm.
  • Material:
    • hubs: high strength fiber reinforced plastic

    • elastomer insert: precision molded wear-restistant and thermally stable polymer
  • Speeds: See below (table), higher speeds on request.
  • Properties of Elastomer Coupling model TX1:
    • economically priced
    • low moment of inertia
    • vibration damping
    • electrically insulating
    • corrosion resistant
    • low backlash, due to keyway connection
