NM128 technical data<\/h2>\n<\/div>\n

NM128 doubles the nominal torque of NM112 to 140 N.m and increases maximum bore to 55 mm. It is a practical candidate for machinery where shaft diameter and starting load have moved beyond the lighter NM sizes.<\/p>\n<\/div>\n

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

The coupling envelope is 128 mm in diameter with a 70 mm length. Measure the actual space between surrounding structures rather than relying on a previous model number, because a larger hub can solve a bore issue while creating a guard-clearance problem.<\/p>\n<\/div>\n

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

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

For mixers, conveyors, pumps and similar industrial drives, use the 140 N.m nominal rating as the first screen and describe how the machine starts. A loaded conveyor start and a steady pump at the same running power do not impose the same transient conditions.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Allineamento e assemblaggio<\/h2>\n

The stated separation for NM128 is 3.5 +\/- 1.0 mm. Keep radial misalignment within 0.07 mm and angular misalignment within 2.5 degrees, then inspect the elastomer after commissioning if the installation previously showed uneven wear.<\/p>\n

Prepare the NM128 RFQ<\/h2>\n

A useful NM128 quotation request combines mechanical interface and duty data: both bores, both keyways, rpm, torque or motor power, driven machine, quantity and any controlled fit. Attach the shaft drawing when shoulders or unusual keys affect machining.<\/p>\n

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

NBR is standard for the flexible ring. If the drive is near heat, lubricants or process chemicals, identify the exposure and any required material so the elastomer is not chosen by appearance alone.<\/p>\n<\/div>\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

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

NM128 is rated to 3000 rpm; verify actual running speed before final selection.<\/p>\n<\/div>\n

Coppia<\/h3>\n

The nominal rating is 140 N.m. Describe unusual starts, reversing or shock in the enquiry.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

When 55 mm bore capacity or 140 N.m torque is insufficient, review NM148. When the application is comfortably below those limits, NM112 may provide a smaller diameter and shorter assembly.<\/p>\n
