NM couplings belong to the broad family of flexible couplings that transmit torque through hub driving features and an elastomeric element. “Jaw coupling,” however, covers many geometries and element systems. The names are related, not interchangeable specifications.
What actually matters in a comparison
| Articolo | Cosa confermare |
|---|---|
| Element geometry | Must match the hub driving profile; a visually similar spider is not automatically interchangeable. |
| Hub and bore | Check size, bore, keyway and available length. |
| Series rating | Use the rating for the exact series and element, not a generic jaw-coupling number. |
| Manutenzione | Consider how the element is inspected and replaced in the machine layout. |
| Ambiente | Element material and operating exposure can influence the correct series. |
If an existing coupling has no clear NM marking, send the photos and dimensions instead of forcing it into the NM category.
