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

Passforms- och bearbetningskontroller<\/h2>\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

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

Uppriktning och montering<\/h2>\n

NM168 uses S 3.5 +\/- 1.5 mm, with 0.10 mm radial and 2.0 degree angular limits. Alignment should be checked in the machine\u2019s final operating position, especially when heavy connected equipment can settle or move the base.<\/p>\n

Prepare the NM168 RFQ<\/h2>\n

State both shaft bores and keyways, rpm, torque or motor power, driven machine, quantity and destination. If the bore approaches 75 mm, include the exact keyway and fit to support a proper hub-machining review.<\/p>\n

NM194 provides more torque and bore capacity, but its rated speed limit drops to 1500 rpm. Do not move up from NM168 until both the speed change and the larger envelope have been checked.<\/p>\n
