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
