NM50 is an NM flexible coupling size for industrial shaft connections. Its size data gives a first check for bore capacity, operating speed and torque. The finished hubs are machined to the actual shafts, so the driver and driven bores may be different.
NM50 technical specifications
| Parameter | Value | Buyer note |
|---|---|---|
| Gamma di alesaggio | 7-19 mm | Confirm both finished bores independently. |
| Velocità massima di riferimento | 12500 giri/minuto | Compare with the actual operating speed. |
| Coppia normale di riferimento | 1.3 kgf·m | Use with the real machine duty, not as the only selection input. |
Specify both shaft interfaces
The coupling size does not define the finished bore. State the diameter, keyway and fit for Shaft 1 and Shaft 2 separately. If axial space is restricted, include the available hub envelope or an assembly drawing.
Operating information for selection
| Articolo | Cosa confermare |
|---|---|
| Driver | Motor, engine or other driver; include power and operating speed. |
| Driven equipment | Pump, compressor, gearbox, fan, mixer, conveyor or other machine. |
| Duty pattern | Continuous/cyclic service, starts, reversals and shock loading where present. |
| Ambiente | Unusual heat, contamination, oil/chemical exposure or outdoor conditions. |
| Replacement work | Existing marking, photos and measurable hub dimensions. |
Typical applications
NM couplings are commonly used on pumps, compressors, motor-to-gearbox drives, fans, blowers, mixers, conveyors and general industrial machinery. Application suitability depends on the complete duty and shaft interfaces.
