ECHT-FLEX Coupling NES Series (Disc Coupling)
- A small disc coupling ideal for driving small servo motors.
- This is a small disc coupling that uses extra-super duralumin for the hub and spacer material.
- We offer a selection of straight hubs that emphasize torsional rigidity and low inertia hubs with low moment of inertia.
- ・Applicable shaft diameter: Φ4mm to Φ50mm
- Torque range: 0.7 to 300 Nm

Features
-
-High torsional rigidity
The straight hub boasts high torsional rigidity and excellent tracking for servo motor drives, etc. It is ideal for precise control.
-
-Low moment of inertia
The hub and spacer are made of lightweight, high-strength extra-super duralumin, and the low inertia hub's unique shape achieves even lower inertia moment. Ideal for high acceleration/deceleration operations such as servo motor drives.
-
・Non-backlash
Power transmission is entirely by friction coupling, so there is no backlash. Ideal for high-precision positioning.
-
・Easy to install
The hubs on both sides are assembled to ensure coaxiality. The hubs can be fastened to the shaft by simply tightening the two clamp bolts on each side.
-
・Overwhelming selection
We offer a wide range of needs with a total of 56 low inertia hubs and straight hubs, and 3,252 combinations of shaft bore diameters.
-
・Environmentally friendly
This product complies with the regulations on hazardous chemical substances such as RoHS, JIG, PFOS and SVHC (15 substances).
