Properties

  • Design:
    • two coupling hubs are concentrically machined with curved jaws.
    • elastomer inserts are available in type A or B.
    • the two coupling elements are connected with a precise and concentrically machined aluminum tube.
  • Tolerance: Overall clearance between shaft and hub 0.01 to 0.05 mm.
  • Material:
    • clamping hub: up to series 450 high strength aluminum, series 800 and up steel
    • elastomer insert: precision molded, wear resistant,
and thermally stable polymer
    • intermediate tube: up to series 450 precision machined aluminum tube; series 800 and up steel,
composite tubes are also available
  • Speeds: Please advise the application speed when ordering or inquiring about EZ Line shafts.
  • Properties of Elastomer Coupling model EZ2:
    • lateral mounting with split clamping hubs
    • engths up to 4 meters
    • no intermediate support bearing required
    • low moment of inertia
    • vibration damping
    • press fit design
    • backlash free
