It is most useful where compact packaging and small shaft diameters matter as much as transmitted torque. Before choosing it for a small drive, verify that both finished bores stay comfortably inside the 19 mm limit and that the guard leaves room around the 50 mm outside diameter.<\/p>\n<\/div>\n<p><div class=\"ep-table-scroll\" role=\"region\" aria-label=\"Technische Spezifikationen der NM-Kupplung\" tabindex=\"0\"><table><thead><tr><th>Modell<\/th><th>Nenndrehmoment<\/th><th>Geschwindigkeitsbegrenzung<\/th><th>D<\/th><th>D1<\/th><th>d max<\/th><th>L<\/th><th>S<\/th><th>Radial<\/th><th>Angular<\/th><\/tr><\/thead><tbody><tr><td><strong><a href=\"https:\/\/nm-coupling.net\/de\/products\/nm50-flexible-coupling\/\">NM50<\/a><\/strong><\/td><td data-claim-id=\"tclaim:84b9e1c8c18e6e62\">5 <span class=\"ep-unit\">Nm<\/span><\/td><td data-claim-id=\"tclaim:ca4588e86d9dac2f\">3000 <span class=\"ep-unit\">U\/min<\/span><\/td><td data-claim-id=\"tclaim:b44eb8feb20fff98\">50 <span class=\"ep-unit\">mm<\/span><\/td><td data-claim-id=\"tclaim:b8f0b56040e14c46\">33 <span class=\"ep-unit\">mm<\/span><\/td><td data-claim-id=\"tclaim:38199730aaf28cce\">19 <span class=\"ep-unit\">mm<\/span><\/td><td data-claim-id=\"tclaim:335ec8febc78a587\">25 <span class=\"ep-unit\">mm<\/span><\/td><td data-claim-id=\"tclaim:a22f52cb85366afa\">2 +\/- 0.5 <span class=\"ep-unit\">mm<\/span><\/td><td data-claim-id=\"tclaim:6cab9d09097cdd94\">0.03 <span class=\"ep-unit\">mm<\/span><\/td><td data-claim-id=\"tclaim:f1f7287a06ef0521\">3.0 <span class=\"ep-unit\">Grad<\/span><\/td><\/tr><\/tbody><\/table><\/div><p class=\"ep-table-note\">Die Werte f\u00fcr D, D1, d<sub>max<\/sub>, L, S und den Radius werden in Millimetern angegeben.
