U.S. projects may use inch shafts and keyways even when the NM model name is metric. State the units beside every shaft and key dimension so the finished hubs are quoted from the actual interface rather than from a motor frame assumption.<\/p>\n

The final coupling size and machining details should match the actual shaft interfaces and operating duty for the machine.<\/p>\n \n Y\u00eau c\u1ea7u b\u00e1o gi\u00e1 kh\u1edbp n\u1ed1i NM<\/h2>\nN\u1ebfu bi\u1ebft k\u00edch th\u01b0\u1edbc NM, h\u00e3y cung c\u1ea5p \u0111\u01b0\u1eddng k\u00ednh tr\u1ee5c, t\u1ed1c \u0111\u1ed9 v\u1eadn h\u00e0nh, thi\u1ebft b\u1ecb d\u1eabn \u0111\u1ed9ng v\u00e0 s\u1ed1 l\u01b0\u1ee3ng.
