ECHT-FLEX NER Series
Model No. NER□□W~
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~
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.

ECHT-FLEX NEH Series
Model No. NEH□□W/U~
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.
