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.
