On an NM coupling, D and D1 help describe the outside envelope and hub geometry, d max limits the specified bore capacity, L controls axial space, and S gives the model-specific separation value used during assembly.<\/p>\n<h2>d max is usually the first interface check.<\/h2>\n<p>Both shafts have to fit. If one exceeds the specified d max, the model is not a clean candidate even when its torque rating looks comfortable. Moving up a size requires a new envelope check because D and L also increase.<\/p>\n<h2>S belongs in installation, not only in the drawing.<\/h2>\n<p>Use the model\u2019s S value when positioning the hubs. An arbitrary gap can change how the flexible ring sits and can reduce the value of the specified alignment limits. After tightening the machines, re-check the gap and alignment.<\/p>\n<p><a class=\"ep-text-link\" href=\"https:\/\/nm-coupling.net\/th\/products\/\">Open the complete NM dimension table \u2192<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>\u0e15\u0e31\u0e27\u0e2d\u0e31\u0e01\u0e29\u0e23\u0e1a\u0e2d\u0e01\u0e02\u0e19\u0e32\u0e14 NM \u0e15\u0e2d\u0e1a\u0e04\u0e33\u0e16\u0e32\u0e21\u0e40\u0e01\u0e35\u0e48\u0e22\u0e27\u0e01\u0e31\u0e1a\u0e01\u0e32\u0e23\u0e1b\u0e23\u0e30\u0e01\u0e2d\u0e1a\u0e0a\u0e34\u0e49\u0e19\u0e2a\u0e48\u0e27\u0e19\u0e15\u0e48\u0e32\u0e07\u0e46 \u0e44\u0e14\u0e49\u0e41\u0e01\u0e48 \u0e15\u0e31\u0e27\u0e40\u0e23\u0e37\u0e2d\u0e19\u0e20\u0e32\u0e22\u0e19\u0e2d\u0e01 \u0e40\u0e2a\u0e49\u0e19\u0e1c\u0e48\u0e32\u0e19\u0e28\u0e39\u0e19\u0e22\u0e4c\u0e01\u0e25\u0e32\u0e07\u0e14\u0e38\u0e21 \u0e04\u0e27\u0e32\u0e21\u0e08\u0e38\u0e02\u0e2d\u0e07\u0e23\u0e39\u0e40\u0e08\u0e32\u0e30 \u0e04\u0e27\u0e32\u0e21\u0e22\u0e32\u0e27\u0e15\u0e32\u0e21\u0e41\u0e19\u0e27\u0e41\u0e01\u0e19 \u0e41\u0e25\u0e30\u0e23\u0e30\u0e22\u0e30\u0e2b\u0e48\u0e32\u0e07\u0e43\u0e19\u0e01\u0e32\u0e23\u0e1b\u0e23\u0e30\u0e01\u0e2d\u0e1a<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-916","ep_nm_article","type-ep_nm_article","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/nm-coupling.net\/th\/wp-json\/wp\/v2\/ep_nm_article\/916","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nm-coupling.net\/th\/wp-json\/wp\/v2\/ep_nm_article"}],"about":[{"href":"https:\/\/nm-coupling.net\/th\/wp-json\/wp\/v2\/types\/ep_nm_article"}],"wp:attachment":[{"href":"https:\/\/nm-coupling.net\/th\/wp-json\/wp\/v2\/media?parent=916"}],"curies":[{"name":"\u0e14\u0e31\u0e1a\u0e40\u0e1a\u0e34\u0e25\u0e22\u0e39\u0e1e\u0e35","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
