ดูรายละเอียด →NM168 NM flexible coupling with 28-75 mm bore range, 4000 rpm reference maximum speed and 59.5 kgf·m reference normal torque.

NM168 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.
| Parameter | Value | Buyer note |
|---|---|---|
| Bore range | 28-75 มม. | Confirm both finished bores independently. |
| Reference max speed | 4000 รอบต่อนาที | Compare with the actual operating speed. |
| Reference normal torque | 59.5 kgf·m | Use with the real machine duty, not as the only selection input. |
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.
| Item | What to confirm |
|---|---|
| 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. |
| Environment | Unusual heat, contamination, oil/chemical exposure or outdoor conditions. |
| Replacement work | Existing marking, photos and measurable hub dimensions. |
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.
Send both shaft dimensions, operating speed, driven equipment and quantity. Include the existing coupling marking or drawing for replacement work.
