NM67 technical data<\/h2>\n<\/div>\n

NM67 steps up bore capacity to 28 mm while keeping a relatively short 30 mm axial length. It is a useful candidate when a compact machine has outgrown NM50 on shaft size but does not need the larger envelope of the mid-range couplings.<\/p>\n<\/div>\n

Passforms- och bearbetningskontroller<\/h2>\n

The 67 mm outside diameter and 46 mm D1 dimension should be checked against covers, brackets and pump guards. On replacement work, do not assume that an old 25 or 28 mm shaft automatically means NM67; verify the installed envelope and keyway as well.<\/p>\n<\/div>\n

D\u00e4r denna storlek passar<\/h2>\n

With 13 N.m nominal torque and a 3000 rpm speed limit, NM67 can be screened for small pump, fan and general machine drives. The final choice still depends on starting behavior and the driven equipment, not the motor frame alone.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Uppriktning och montering<\/h2>\n

NM67 uses a 2.5 +\/- 0.5 mm separation. Its stated radial allowance is 0.03 mm and angular allowance is 3.0 degrees. Keep those values as commissioning boundaries after final base and piping adjustments.<\/p>\n

Prepare the NM67 RFQ<\/h2>\n

Quote requests should identify the motor-side bore, driven-side bore and their keyways separately. Add actual running rpm and the duty description so the 13 N.m rating is evaluated in the right context.<\/p>\n

When NM67 is close to its torque or bore ceiling, compare NM82. If the duty is much lighter and both shafts fit below 19 mm, NM50 may offer a smaller envelope.<\/p>\n
