ECHT-FLEX Coupling NES Series  (Disk Couplings )

Product photo
  • 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

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.
