Spring Strip Width Tolerance and Guide Fit

Quick answer: It changes the fit within flanges and guides and can alter the actual contact condition.

What does width variation affect besides nominal force?

A wider strip may contact a guide even if its output is acceptable. A narrower strip may have excessive lateral movement. Review width limits together with assembly tolerances. Keep force acceptance and guidance acceptance as separate checks.

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.
