Quick answer: Housing roundness, concentricity and contact can alter assembled friction. Compare housings before attributing all scatter to spring manufacture.
Why do identical springs behave differently in different housings?
A local tight region may contact the coil at a particular angular position. The disturbance can appear as torque ripple or reduced available travel. Use a known-good spring across several measured housings to distinguish part variation from assembly geometry.
A practical verification method
Correlate torque disturbance position with housing measurements and visible contact marks.
| 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 | Correlate torque disturbance position with housing measurements and visible contact marks. | 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.
