Choose a complete NM coupling, replacement flexible element or related coupling family.<\/h2>\n<\/div>\n

NM50 through NM214 cover a broad range of shaft sizes and industrial drive duties. Start with the complete coupling range when you know torque and shaft data, or send the existing size and operating conditions for replacement parts.<\/p>\n<\/div>\n

Why NM<\/span><\/p>\n

A compact flexible connection for common industrial drives.<\/h2>\n<\/div>\n

Two hubs engage an elastomer element that transmits torque while adding damping and allowing limited shaft misalignment. The result is a simple coupling format that is easy to inspect and replace when the machine layout provides suitable access.<\/p>\n<\/div>\n

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

Vibration damping<\/h3>\n

The flexible element reduces direct transmission of vibration between the driving and driven machines.<\/p>\n<\/div>\n

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

Lubrication-free<\/h3>\n

Routine attention centres on alignment, hub security and the condition of the flexible element.<\/p>\n<\/div>\n

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

Alignment allowance<\/h3>\n

Each model has defined radial and angular limits that should be checked after installation.<\/p>\n<\/div>\n

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

Custom bores<\/h3>\n

Different driving and driven shaft bores can be specified within the selected model’s machining limits.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

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

NM couplings for pumps, compressors and general rotating equipment.<\/h2>\n<\/div>\n

Selection changes with the machine duty. Torque, speed, both shaft interfaces, starting conditions, shock and alignment should be considered together.<\/p>\n<\/div>\n

\n
\n
\n
Selection workflow<\/span><\/p>\n

Four checks before you place the order.<\/h2>\n<\/div>\n

Outside diameter alone is not enough. The selected model must carry the duty, accept both shafts and fit the available space.<\/p>\n<\/div>\n

\n
\n

Define the duty<\/h3>\n

Use operating torque or motor power and speed, then add starts, shock, reversing and the driven machine.<\/p>\n<\/div>\n

\n

Choose a model<\/h3>\n

Select a size whose nominal torque and rated speed cover the operating point.<\/p>\n<\/div>\n

\n

Check both shafts<\/h3>\n

Confirm each bore, keyway and the available envelope against d max, D, D1 and L.<\/p>\n<\/div>\n

\n

Send the RFQ<\/h3>\n

Include quantity, destination, elastomer or material requests and any unusual operating conditions.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n
