More Information
Precautions for Use
1. Avoid rough handling. The couplings are highly reliable in light loading applications. They are suitable for potentiometers and encoders.
2. Do not apply excessive bending and torsional forces during installation.Be sure to maintain tightening torque for set screws. (Resin material breaks if the tightening torque exceeds the allowable range)
3. The couplings have been proven with heat-run tests that show 10 years of service life and 10^8 revolutions if used at under the allowable torque and misalignment values.

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.
Caution
Precautions for use
- 1.The couplings are highly reliable in light loading applications. They are suitable for potentiometers and encoders.
- 2.Avoid rough handling. Do not apply excessive bending and torsional forces during installation. Be sure to maintain tightening torque for set screws. (Resin material breaks if the tightening torque exceeds the allowable range)
- 3.The couplings have been proven with heat-run tests that show 10 years of service life and 108 revolutions if used under the allowable torque and misalignment values.
- For small misalignment, use one MCJ Series for connection.
- For large misalignment, use two MCJ Series for connection.
