НМ148 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.

NM148 technical specifications

Parameter Value Buyer note
Bore range 22-65 мм Confirm both finished bores independently.
Reference max speed 4500 об/хв Compare with the actual operating speed.
Reference normal torque 41.7 kgf·m Use with the real machine duty, not as the only selection input.

Specify both shaft interfaces

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.

Operating information for selection

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.

Typical applications

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.
