NM148 technical data<\/h2>\n<\/div>\n

NM148 carries 280 N.m nominal torque and allows up to a 65 mm bore while retaining the 3000 rpm speed class. It is often the point where buyers should treat the coupling as a significant machine interface rather than a small accessory.<\/p>\n<\/div>\n

Verifiche di montaggio e lavorazione<\/h2>\n

The 148 mm outside diameter, 107 mm D1 and 80 mm length need to be compared with guards, supports and shaft projections. Large finished bores should be quoted with their keyway and fit so the remaining hub geometry is considered before production.<\/p>\n<\/div>\n

Servizio operativo<\/span><\/p>\n

Dove questa taglia si adatta<\/h2>\n

Use NM148 for initial review of higher-load pumps, mixers, conveyors and process machinery when the operating torque stays within the model rating. Report loaded starts, reversing or jams separately because transient duty may control the final selection.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Allineamento e assemblaggio<\/h2>\n

Set the hubs to S 3.5 +\/- 1.0 mm. The stated radial limit is 0.07 mm and the angular limit is 2.0 degrees. If repeated elastomer wear appears, inspect alignment and hub movement rather than treating the ring as the only maintenance item.<\/p>\n

Prepare the NM148 RFQ<\/h2>\n

For an NM148 order, include shaft diameters and keyways, running rpm, design torque or motor power, starting conditions and quantity. A machine drawing is particularly useful when the requested bore is close to 65 mm.<\/p>\n

Condizioni dei materiali e di servizio<\/h2>\n<\/div>\n

The normal element material is NBR. For demanding environments, specify temperature and oil or chemical contact plus any requested alternative material or hardness in the commercial enquiry.<\/p>\n<\/div>\n

Elemento<\/h3>\n

Indicare il materiale richiesto o l'ambiente di utilizzo; non identificare la composizione chimica dell'elastomero solo in base al colore.<\/p>\n<\/div>\n

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

Lavorazione meccanica<\/h3>\n

Elencare separatamente i fori di azionamento e di condotto e le sedi delle chiavette, includendo gli accoppiamenti controllati ove richiesto.<\/p>\n<\/div>\n

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

Velocit\u00e0<\/h3>\n

NM148 is rated to 3000 rpm; verify actual running speed before final selection.<\/p>\n<\/div>\n

Coppia<\/h3>\n

The nominal rating is 280 N.m. Describe unusual starts, reversing or shock in the enquiry.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

If the application needs more than 280 N.m or a bore larger than 65 mm, compare NM168. If duty and bore are lower, NM128 can be checked to reduce overall diameter and length.<\/p>\n
