NM112 technical data<\/h2>\n<\/div>\n

NM112 opens the mid-range group with 70 N.m nominal torque and a 48 mm maximum bore. It is often evaluated when a drive has a noticeably larger shaft interface but still operates within a 3000 rpm limit.<\/p>\n<\/div>\n

Contr\u00f4les d'ajustement et d'usinage<\/h2>\n

At 112 mm outside diameter and 60 mm length, installation space becomes more visible in the selection. Check guard diameter, shaft projection and access for the flexible element before fixing the bore dimensions on the drawing.<\/p>\n<\/div>\n

Fonctionnement<\/span><\/p>\n

O\u00f9 cette taille convient<\/h2>\n

Pumps, mixers, conveyors and general machinery can bring different starting behavior to the same nominal power. For NM112, state whether the drive starts loaded, cycles frequently or sees process shock so the application can be reviewed beyond its 70 N.m continuous rating.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Alignement et assemblage<\/h2>\n

NM112 uses S 3.5 +\/- 1.0 mm, with 0.07 mm radial and 2.5 degree angular limits. Measure alignment after final machine tightening because base distortion or connected piping can move the shafts from an earlier workshop setting.<\/p>\n

Prepare the NM112 RFQ<\/h2>\n

Send both shaft diameters, keyways, speed and duty, plus quantity and destination. If either bore approaches 48 mm, include the keyway and fit requirement so the machining request can be checked with the available hub section.<\/p>\n

The standard flexible element is NBR. For elevated temperature, chemical exposure or a nonstandard hardness request, give the service conditions with the NM112 enquiry so the quoted element can be specified clearly.<\/p>\n<\/div>\n

Comparez les tailles NM les plus proches<\/h2>\n

If NM112 is too small on bore or torque, compare NM128. If its 112 mm diameter creates a packaging problem and the load permits, NM97 is the nearest smaller alternative to review.<\/p>\n
