NM67 Flexible Coupling
NM67 provides 13 N.m nominal torque, up to 28 mm bore capacity and a rated speed limit of 3000 rpm. It is suited to compact pumps, fans and light machinery when torque, shaft fit, alignment and installation space are all within the model limits.
NM67 technical data
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.

فحوصات الملاءمة والتشغيل الآلي
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.
حيث يناسب هذا المقاس
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.
المحاذاة والتجميع
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.
Prepare the NM67 RFQ
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.
شروط المواد والخدمة
Specify the elastomer by material requirement rather than colour. NBR is standard for this range; unusual temperature or fluid exposure should be stated before the replacement element is confirmed.
قارن بين أقرب أحجام النانومتر
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.
