    Properties

    • Design:
      • two coupling hubs are concentrically machined with curved jaws.

      • bore tolerance H7 + keyway + set screw per DIN 916 or optional pilot bore (DV).
    • Temperature range: The temperature range depends on the Elastomer insert.
    • Tolerance: Overall clearance between shaft and hub 0.01 to 0.05 mm.
    • Material:
      • coupling hub: up to series 450 high strength aluminium, series 800 and up steel

      • elastomer insert: precision molded, wear resistant, and thermally stable polymer
    • Speeds: See table below *Please contact R+W
                    ISO 2.5 balance grade available
    • Properties of Elastomer Coupling model EK1:
      • economical design
      • concentrically machined
      • vibration damping
      • electrically isolating
      • press fit design
      • low backlash, due to keyway connection
