Conveyors
NM couplings for conveyor drive trains, including loaded starts and gearbox connections.
Conveyor starting duty varies widely. A lightly loaded belt conveyor and a heavily loaded screw conveyor can require very different coupling decisions even with similar motor power.
What to include in the application RFQ
| Item | What to confirm |
|---|---|
| Conveyor type | Belt, roller, screw or other conveying mechanism. |
| Starting condition | Loaded or unloaded start, start frequency and control method. |
| Drive train | Motor and gearbox data where a gearbox is used. |
| Shafts | Both coupling bores, keyways and available space. |
Where an NM coupling fits
For motor-to-gearbox conveyor drives, select the NM coupling from the input-side duty and shaft interfaces. For direct drives, include the actual driven shaft details and the conveyor start condition.
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.
