ECHT-FLEX NER Series

Model No. 　NER□□W～

Go to Model No. Selection

Original center unit structure that is easy to install, and realizes a compact and large transmission capacity.

  • ・High kW ratings ：
    New disc style coupling provides substantially higher torque than with conventional series.
  • ・Superior handleability ：
    Original center unit structure that combines the discs and spacer eliminates troublesome disc assembly at the worksite. Just attach or remove bolts to attach or remove the center unit.
  • ・Can be used with large shaft bore diameters ：
    The center unit allows for larger maximum bore diameters than with conventional series.
  • ・Non-backlash, no lubrication, and long life ：
    Ideal for equipment that positions with a servomotor as the coupling has no backlash and a high torsional stiffness.
    No need for lubrication as there are no sliding areas.
  • ・Wide variety of options available ：
    A wide variety of combinations are available, including coupling types by Power Locks, flange mounted types, and others.

ECHT-FLEX NES Series

Model No. 　NES□□W/S～

Go to Model No. Selection

The small disk coupling with the hub and spacer made of extra super duralumin.

  • ・Low moment of inertia ：
    Provides low inertia moment by employing light-weight and high-strength extra super duralumin for the hub and spacer.
  • ・High torsional stiffness ：
    The straight hub features high torsional stiffness and excellent responsiveness for servomotor drives. Most suitable for precise control.
  • ・Extensive Lineup ：
    Can meet the wide variety of needs with 56 combinations of low inertia and straight hubs, supporting 3252 patterns of different shaft bore diameters.
  • ・Non-backlash ：
    Perfect for high-precision positioning operation.
  • ・High torque, secure shaft coupling force ：
    The unique clamp geometry provides increased clamping force on shafts.
  • ・Easy mounting ：
    Both sides of the hub are centered with a special jig, and are assembled to ensure concentricity.
    Can be connected with the shaft by simply tightening one clamp bolt on each side.

Go to Model No. Selection

This large-size series can be used up to 176,000N・m{18,000kgf・m}.

  • ・Large-size, spacer type couplings.
  • ・In addition to the standard hub (N hub), an adapter hub (A hub) that can have larger shaft bore diameter, and a unit spacer hub (U hub) that allows the spacer unit to be removed and assembled without disassembling the disc coupling unit, are also available.
  • ・Gear coupling replacement type can also be manufactured to replace gear couplings.
  • ・Long spacer type can be manufactured upon request.
  • ・It is also possible to manufacture electrically insulated type using split spacers and insulating bolt sets.
  • ・If you like to coupling other than the key, please contact us.
