L'aspect du produit varie selon la taille de l'accouplement et l'alésage fini. Consultez le tableau des modèles ci-dessous pour les dimensions et transmettez les spécifications des deux arbres pour l'usinage.
NM50 Flexible Coupling
NM50 provides 5 N.m nominal torque, up to 19 mm bore capacity and a rated speed limit of 3000 rpm. It is suited to compact pumps, fans and light machinery when torque, shaft fit, alignment and installation space are all within the model limits.
NM50 technical data
NM50 is the smallest coupling in this range. It is most useful where compact packaging and small shaft diameters matter as much as transmitted torque. Before choosing it for a small drive, verify that both finished bores stay comfortably inside the 19 mm limit and that the guard leaves room around the 50 mm outside diameter.
| Modèle | Couple nominal | Limitation de vitesse | D | D1 | d max | L | S | Radial | Angulaire |
|---|---|---|---|---|---|---|---|---|---|
| NM50 | 5 Nm | 3000 tr/min | 50 mm | 33 mm | 19 mm | 25 mm | 2 +/- 0.5 mm | 0.03 mm | 3.0 deg |
Les valeurs D, D1, d max, L, S et radiales sont exprimées en millimètres. Le déplacement angulaire est indiqué en degrés. Sur les petits écrans, faites glisser le tableau horizontalement pour afficher toutes les colonnes.
Contrôles d'ajustement et d'usinage
This size has little spare hub section for an oversized keyway or an aggressive bore request. Send both shaft diameters and keyways early. If one shaft is near the model limit, the bore detail should be reviewed together with torque rather than treated as a simple machining instruction.
Où cette taille convient
Use NM50 as a starting point for low-torque pumps, fans, auxiliaries and compact machinery only when the real operating point fits its 5 N.m nominal rating. Frequent starts or shock can matter even on a small motor, so include them in the enquiry.
Alignement et assemblage
The stated alignment values for NM50 are 0.03 mm radial and 3.0 degrees angular. Set the 2 +/- 0.5 mm separation after the connected machines are tightened, then re-check alignment before the guard is closed.
Prepare the NM50 RFQ
For an NM50 quotation, send speed, torque or motor power, the two shaft sizes, both keyways, quantity and destination. A simple photo or shaft sketch is useful when the coupling replaces an unknown small component.
Conditions matérielles et de service
NBR is the standard flexible-element material. For a small high-cycle drive, include temperature, oil exposure and start frequency if they could affect the elastomer selection.
Comparez les tailles NM les plus proches
If either shaft will not fit the 19 mm bore limit, compare NM67 instead of forcing the NM50 hub. The larger size also changes the outside envelope, so check available space again.
