ECHT-FLEX Coupling NES Series (Disk Couplings )
- This small disk coupling is ideal for a small servomotor drive.
- The small disk coupling with the hub and spacer made of extra super duralumin.
- The straight hub focused torsional stiffness, and the low inertia hub even for lower inertia are available.
- ・Applicable shaft diameter :Φ4mm~Φ50mm
- ・Torque range :0.7~300N・m
Kind of hub
- ・Emphasis on torsional stiffness
Straight hub
- ・Emphasis on Low inertia
Low inertia hub
- ・Utilization of both characteristics
Low Inertia x Straight Hub
Features
-
・High torsional stiffness
The straight hub features high torsional stiffness and excellent responsiveness for servomotor drives. Most suitable for precise control.
-
・Low moment of inertia
Provides low inertia moment by employing light-weight and high-strength extra super duralumin for the hub and spacer, and by unique configuration for the low inertia hub. Ideal for high acceleration/deceleration operations such as a servomotor drive.
-
・Non-backlash
There is no backlash as all torque is transmitted by friction connections. Perfect for high-precision positioning.
-
・Easy mounting
Both sides of the hub are assembled to ensure concentricity. Can be connected with the shaft by simply tightening one clamp bolt on each side.
-
・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.
-
・Environmentally Friendly
This product is compliant with the RoHS directive, as well as hazardous chemical substance regulations JIG, PFOS and 15 SVHCs.
