Properties

  • Design:
    • two split clamping hubs on each end are concentrically machined with curved jaws.
    • elastomer inserts are available in type A or B. Both coupling bodies are solidly joined to the tubes with a high level of concentricity.
    • loosening the intermediate clamp allows for a variation of length and rotational orientation.
  • Tolerance: Overall clearance between shaft and hub 0.01 to 0.05 mm.
  • Material:
    • clamping hub: high strength aluminum
    • elastomer insert: precision molded wear resistant, and thermally stable polymer
    • intermediate tubes: precision machined aluminum tube, steel or composite tube are upon request available
  • Speeds: To control the critical resonant speed please advise the application speed when ordering or inquiring about EZ Line Shafts.
  • Properties of Elastomer Coupling model EZV:
    • lateral mounting with split clamping hubs
    • lengths up to 4 meters
    • adjustable in length
    • low moment of inertia
    • vibration damping
    • press fit designs
    • backlash free
