ECHT-FLEX NER Series
Model number NER□□W~
It has a unique center unit structure that is easy to install, and achieves a compact size with great transmission capacity.
- ・Large transmission force:
The new disc shape has resulted in a significant increase in torque compared to the previous series. - ・Outstanding ease of use:
The unique center unit structure that integrates the disk and spacer eliminates the need for troublesome disks at the site.
No assembly work is required. Installation and removal is simply a matter of removing and attaching the bolts between the center unit and the hub. - ・Compatible with large shaft hole diameters:
The center unit structure allows for a larger maximum shaft bore diameter than the previous series. - ・Non-backlash, no lubrication required, long life:
It has no backlash and high torsional rigidity, making it suitable for servo motor positioning devices.
Also, since there are no sliding parts, there is no need for lubrication. - ・Wide range of options available:
A wide range of combinations are possible, including shaft fastening with Power-Lock and flange mounting.

ECHT-FLEX NES Series
Model number NES□□W/S~
This is a small disc coupling that uses extra-super duralumin for the hub and spacer material.
- ・Low moment of inertia:
The hub is made of lightweight, high-strength extra-super duralumin, which, combined with the unique hub shape, achieves low inertia.
- ・High torsional rigidity:
The straight hub boasts high torsional rigidity and excellent tracking for servo motor drives, making it ideal for precise control. - ・Overwhelming product lineup:
A combination of low inertia hubs and straight hubs allows for 56 different product types and 3,252 different shaft hole diameter combinations. - ・Non-backlash:
Ideal for high-precision positioning operations. - ・High torque and reliable shaft fastening force:
The unique clamp shape increases the shaft fastening force. - Easy to install:
The hubs on both sides are centered using a special jig to ensure coaxiality during assembly.
The shaft is fastened using a clamping method, and can be installed by simply tightening the two clamp bolts on both sides.

ECHT-FLEX NEH Series
Model number NEH□□W/U~
This is a large disc coupling that can be used with a maximum torque of 176,000 Nm.
- - A large, spacer-type coupling.
- In addition to the standard hub (N hub), there is also an adapter hub (A hub) that allows for a larger shaft hole diameter, and the disc connection part can be disassembled.
We offer a range of unit spacer hubs (U-hubs) that allow for easy removal and assembly of spacer units without the need for additional spacers. - - Gear coupling compatible specifications can also be manufactured for replacing gear couplings.
- -Long spacer types can also be manufactured.
- - Electrically insulated specifications can also be manufactured using split spacers and insulating bolt sets.
- If you require fastening other than with a key, please contact us.
