Features

Disc Couplings

Zero backlash, and best suited for high torque servo motor applications. characteristics.

  • Designed to absorb misalignments by disc flexures.
  • Zero backlash nature provides high angular accuracy, suitable for applications requiring high positioning accuracies.
  • The High Rigidity Type couplings have largely improved torsional rigidity over the Standard Types due to screw-coupled discs instead of the swage-coupled discs of the Standard.

Cautions

Use Precautions

  • Make sure to keep misalignment within the allowed range and avoid excessive torque. Otherwise the coupling’s life will be shortened considerably due to plastic deformation.
  • For your safety, enclose the revolving parts of equipment with a protective cover.
  • If the coupling item generates abnormal metallic noises, immediately turn off the equipment and identify the cause. Such noises may be an indication of improper alignment, shaft interference or a loose screw.
  • For applications with a large load fluctuation, apply an adhesive agent on the coupling’s screws to prevent them from loosening. Alternatively, select a coupling of a larger size/load capability.
