Features

Slit Couplings

Integrated structure with no backlash.

Slits designed to allow misalignments.
Suitable for applications requiring high positioning accuracies due to zero backlash nature.
Consider the Disc Types if higher torque transmission capability is needed.

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.
