Quick answer: Use the cable manufacturer's approved limit for the actual cable and duty, then check the reel hub and all guidance points.
Who defines the cable bend-radius limit?
A spring mechanism cannot make an unsuitable cable bend safe. Static storage and repeated bending may have different limits. The cable cross-section, shielding and connector strain relief must be part of the reel design input.
A practical verification method
Verify hub and guide geometry against the selected cable documentation and validate repeated bending in the assembled reel.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Verify hub and guide geometry against the selected cable documentation and validate repeated bending in the assembled reel. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
