The important word is \u201csome.\u201d The model values are limits for a model, not a target installation condition.<\/p>\n<h2>Misalignment consumes elastomer capacity.<\/h2>\n<p>When a coupling spends its entire operating life correcting a large fixed offset, the flexible ring is already working before torque variation and vibration are added. Better base alignment leaves more margin for small movement that occurs during operation.<\/p>\n<h2>Check after tightening, not only before.<\/h2>\n<p>Machine feet, guards, piping and connected equipment can shift the final shaft positions. Measure after the assembly is secured, and check again if an elastomer shows repeated one-sided wear.<\/p>\n<p><a class=\"ep-text-link\" href=\"https:\/\/nm-coupling.net\/ur\/technical-guides\/installation-alignment\/\">Open the installation and alignment guide \u2192<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Flexibility provides limited misalignment accommodation and damping; it does not turn misalignment into a maintenance-free operating condition.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-920","ep_nm_article","type-ep_nm_article","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/nm-coupling.net\/ur\/wp-json\/wp\/v2\/ep_nm_article\/920","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nm-coupling.net\/ur\/wp-json\/wp\/v2\/ep_nm_article"}],"about":[{"href":"https:\/\/nm-coupling.net\/ur\/wp-json\/wp\/v2\/types\/ep_nm_article"}],"wp:attachment":[{"href":"https:\/\/nm-coupling.net\/ur\/wp-json\/wp\/v2\/media?parent=920"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
