Precautions
■ Calibration and adjustment
1. The Flexible Shaft Couplings allows axis deviation, and transmits rotation angle and torque, but when the axis deviation exceeds the allowable value, vibration will occur or the service life will be drastically reduced. Be sure to make calibration andadjustment.
2. Axis deviation includes lateral misalignment (parallel error of two axes), angular misalignment (angular error of two axes) and axial amplitude (axial movement of shaft).
Please calibrate and adjust the shaft to ensure that the axis deviation is below the allowable value recorded in the dimension and performance table of each product.
3. The allowable value of axis deviation recorded in the dimension and performance table refers to the situation when either lateral misalignment, angular misalignment or axial amplitude occurs alone. When more than two axis deviationsoccur at the same time, the corresponding allowable values are halved respectively.
4. Axis deviation not only occurs when assembling to the device, but also is caused by vibration, thermal expansion and bearing wear in operation. Therefore, it is recommended to set the axis deviation below 1/3 of the allowable value.

Usage Method
■Mounting method
STEP1 Insert the coupling
Confirm that the clamping bolt has been unscrewed, and then remove the dust, foreign matter and oil from the shaft and coupling bore.
Then, when inserting the Flexible Shaft Couplings into the shaft, please be careful not to put the disc under excessive stress such as compression or tension.
STEP2 Use fixture to adjust
Please use fixture to adjust and fix the concentricity of the left and right hubs of the coupling with high accuracy.
STEP3 Simple lateral misalignment and angular misalignment confirmation
Under the condition of unscrewed bolts, make the Flexible Shaft Couplings slide axially and confirm its smooth movement.
Then, rotate the coupling to make sure it moves smoothly.
Lateral misalignment is not allowed for single disc type coupling, so carry out positioning securely.
STEP4 Installation
Please adjust the shaft insertion amount according to the dimension ℓ in the product catalog, and use a torque wrench to tighten with the specified torque.
＊ If the specified torque cannot be reached once, please cross fasten the left and right clamps twice or three times.

Frequently asked question (FAQ)FAQ
- Question:Question: What are the characteristics of claw couplings?
- Answer:Answer: Claw couplings can absorb vibration, compensate radial and angular deviation, and are maintenance free, oil resistant and electrically insulated.
- Question:Question: What are the applications of claw couplings?
- Answer:Answer: Applicable motor types for claw couplings: recommended for stepping motors and universal motors.
- Question:Question: How to select according to the purpose, environment, working conditions?
- Answer:Answer: Please refer to the link page for specific instructions. https://www.misumi.com.cn/special/coupling/select/situation/
- Question:Question: What is a coupling?
- Answer:Answer: A coupling is a part that connects two different rotating bodies (motor shaft, ball screw, etc.) and aims at transmitting torque. The load of assembly adjustment is reduced by absorbing the axis deviation (lateral misalignment, angular misalignment and axial amplitude) between rotating bodies. And in case of accidental overload, the coupling is destroyed and the rotating bodies are disconnected to protect the expensive power part and the whole device.
