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\/fa\/technical-guides\/installation-alignment\/\">Open the installation and alignment guide \u2192<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>\u0627\u0646\u0639\u0637\u0627\u0641\u200c\u067e\u0630\u06cc\u0631\u06cc\u060c \u062a\u0637\u0628\u06cc\u0642 \u0648 \u0645\u06cc\u0631\u0627\u06cc\u06cc \u0645\u062d\u062f\u0648\u062f\u06cc \u0627\u0632 \u0646\u0627\u0647\u0645\u200c\u062a\u0631\u0627\u0632\u06cc \u0631\u0627 \u0641\u0631\u0627\u0647\u0645 \u0645\u06cc\u200c\u06a9\u0646\u062f\u061b \u0648 \u0646\u0627\u0647\u0645\u200c\u062a\u0631\u0627\u0632\u06cc \u0631\u0627 \u0628\u0647 \u06cc\u06a9 \u0648\u0636\u0639\u06cc\u062a \u0639\u0645\u0644\u06cc\u0627\u062a\u06cc \u0628\u062f\u0648\u0646 \u0646\u06cc\u0627\u0632 \u0628\u0647 \u062a\u0639\u0645\u06cc\u0631 \u0648 \u0646\u06af\u0647\u062f\u0627\u0631\u06cc \u062a\u0628\u062f\u06cc\u0644 \u0646\u0645\u06cc\u200c\u06a9\u0646\u062f.<\/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\/fa\/wp-json\/wp\/v2\/ep_nm_article\/920","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nm-coupling.net\/fa\/wp-json\/wp\/v2\/ep_nm_article"}],"about":[{"href":"https:\/\/nm-coupling.net\/fa\/wp-json\/wp\/v2\/types\/ep_nm_article"}],"wp:attachment":[{"href":"https:\/\/nm-coupling.net\/fa\/wp-json\/wp\/v2\/media?parent=920"}],"curies":[{"name":"\u0648\u0631\u062f\u067e\u0631\u0633","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
