NM168 technical data<\/h2>\n<\/div>\n

NM168 is the highest-torque size in this range that still carries a 3000 rpm rated speed limit. With 500 N.m nominal torque and a 75 mm maximum bore, it can cover substantial machinery interfaces without the speed reduction that begins at NM194.<\/p>\n<\/div>\n

The outside diameter is 168 mm and the axial length is 90 mm. Verify both the rotating clearance and service access around the coupling; a high-capacity model is not useful if the guard or adjacent equipment prevents correct assembly and inspection.<\/p>\n<\/div>\n

For larger pumps, process drives and general machinery, screen NM168 against the 500 N.m nominal rating, then add the true starting and shock behavior. Its 3000 rpm limit is an important differentiator when comparing it with the next larger sizes.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
