Machine Tool Products -- Couplings

Tsubaki couplings are the best choice for coupling main spindles and servo motors, and servo motors for the X-/Y-/Z-axes feed spindles and ball screw.

NEF Taper Lock Series Echt-Flex® Coupling (for main spindle and feed spindle applications)  >>>Click for product data

  • Demonstrates high performance for high speed drives thanks to its balanced design and precision assembly balance. (Max. RPM is 15,000rpm/G2.5)
  • For main spindle applications, we precisely assemble the unit and adjust the balance before shipping.
  • The optimally shaped disc, based on FEM, features high torsional rigidity and superb flexibility. There is no backlash either.
  • Applicable torque range:
    39.2 - 245N·m
  • Applicable spindle bore diameter range:
    10 - 50mm

NES Series Echt-Flex® Coupling (for main spindle and feed spindle applications)  >>>Click for product data

  • The hub uses lightweight, high strength extra super Duralumin, and the unique hub shape realizes a low moment of inertia. There is no backlash either.
  • It fastens to the spindle using a clamping method -- just tighten the clamp bolts on either side of the coupling for easy attachment.
  • We can also provide balance adjusted couplings with taper lock mechanisms for main spindle applications.
  • Applicable torque range:
    0.7 - 300N·m
  • Applicable spindle bore diameter range:
    4 - 50mm

LN Series Jaw-Flex Coupling (for main spindle and feed spindle applications)  >>>Click for product data

  • The spider uses a new material with unsurpassed vibration damping properties. It absorbs vibration during table feed so as to not damage work piece machining quality.
  • Users can select from two spider types: 98A with excellent vibration damping properties and 64D with high torsional rigidity and superb wear resistance. These jaw-type couplings still provide torque transmission with no backlash.
  • It fastens to the spindle using a clamping method -- just tighten the clamp bolts on either side of the coupling for easy attachment. We can also provide couplings with taper lock mechanisms for main spindle applications.
  • Applicable torque range:
    60 - 405N·m
    (normal spider transmission torque)
  • Applicable spindle bore diameter range:
    12 - 42mm

Power Rigid Coupling (for feed spindle applications)  >>>Click for product data

  • Its design uses no flexible elements to give it high torsional rigidity.
  • Uses a taper lock method to realize a large spindle fastening strength.
  • The outer race has a polygonal shape for a lower moment of inertia and no backlash.
  • Its simple design and common parts can greatly lower your costs.

Does not absorb misalignment.

  • Applicable torque range:
    78 - 489N·m
  • Applicable spindle bore diameter range:
    16 - 35mm

Clamp Type Rigid Coupling (customized product for feed spindle applications)

  • A simple, rigid coupling that fastens to spindles using a clamp method.
  • The body uses carbon steel, with aluminum types also available.
  • Can be used on taper shafts with no backlash.
  • Mass produced in large quantities to help you lower costs.

Cannot absorb misalignment.
