Vifter og blåsere
NM couplings for fan and blower drives where operating speed and alignment matter.
Fan and blower drives are often continuous-duty applications. At higher speed, accurate shaft data, alignment and the condition of the rotating equipment become especially important.
What to include in the application RFQ
| Punkt | Hva som skal bekreftes |
|---|---|
| Operating speed | Normal and maximum running rpm. |
| Fan / blower | Equipment type and any load changes caused by control method. |
| Sjakter | Both diameters, keyways and available coupling space. |
| Condition | Existing vibration, bearing or alignment concerns on replacement jobs. |
Where an NM coupling fits
Use the NM size table to identify models that can accept both shafts and the operating speed. If vibration is already present, address the machine condition rather than expecting the coupling to compensate for a mechanical fault.
Replacement and installation notes
For replacement work, include the existing coupling marking, photos and measurable hub dimensions. For new installations, provide the shaft drawing or actual shaft dimensions. Align the connected equipment to the machine manufacturer’s requirements before operation.
Request an NM Coupling Quote
Send the NM size if known, both shaft diameters, operating speed, driven equipment and quantity. Add a drawing or photos for replacement work.
