Tsubaki's Power Rigid Coupling is a rigid coupling for machine tools. It employs a taper-lock structure to ensure a more reliable connection.

  • ・Compatible with straight shafts and taper shaft. ：
    Compatible with taper shaft servomotors. Apply Φ11 taper shafts and adaptors for Φ16 taper shafts.
  • ・High Torsional Stiffness ：
    Does not have a flexible structure, this type has high rigidity.
  • ・Non-backlash ：
    There is no backlash due to the friction of the coupling through a taper-lock.
  • ・Compact & Low Moment of Inertia ：
    The axial length is maximally reduced, allowing for more compact design. Also provides lower moment of inertia through the polygonal outer ring configuration.
