NM 112 フレキシブルジョーカップリング
NM 112 reference model with 14-48 mm bore range, 6000 rpm maximum reference speed, and forged-iron hub construction shown in the supplied reference page. Final bore, keyway and duty require confirmation.
NM 112 is listed with 16.7 Kg*m normal torque, 30 Kg*m maximum torque and 6,000 rpm maximum reference speed. Its bore range is 14-48 mm, boss diameter 79 mm, outside diameter 112 mm and approximate weight 5.40 kg. This model is a practical mid-size checkpoint when both shaft capacity and a moderate installation envelope matter.
- Mid-size reference OD 112 mm
- Normal/max values 16.7/30 Kg*m
- Speed reference 6000 rpm
- Document VFD or cycling behavior
- Finalize bore and axial location by drawing
Mid-Size Reference
The NM 112 data below records the provided model-sheet values for engineering discussion. Final manufacturing and operating approval require the actual project interfaces and duty.

Construction Baseline
The supplied reference page identifies forged iron at the hub and depicts a flexible center member between the opposing jaws. For NM 112, treat that as the documented construction baseline. Element hardness or polymer chemistry is not supplied, so requests involving heat, oil, solvents or unusually soft torsional behavior require separate confirmation rather than an inferred material claim.
Combined Sizing Check
The key NM 112 question is whether the drive duty and shaft pair fit the same size at the same time. Provide motor kW/HP and rpm or transmitted torque, then add starting or shock information. Check each bore and keyway independently. The 6,000 rpm reference number should be treated as a model-data limit; high-speed applications need the full final configuration reviewed, including machining, balance and mounting.
Installation Baseline
Plan lifting and access before installation because the assembly is larger than the smallest NM entries. Confirm the driver and driven shafts are supported correctly, slide or fit each hub to its specified position, and establish alignment before the element is used to connect them. After commissioning, document hub movement, element condition and any recurring vibration so maintenance has a baseline for comparison.
Operating Profile
NM 112 may be shortlisted for pumps, compressors, fans, gearboxes and other motor-driven machinery where the reference limits are compatible with the calculated duty. If the machine has a VFD, frequent ramping or rapid cycling, state that operating profile. The coupling review should reflect how the machine actually accelerates and loads, not only the nameplate power.
OEM Interface Options
Possible RFQ customization includes two different finished bores, keyways, fit tolerances, identification marks and project packaging. If the existing installation uses a nonstandard shaft shoulder or restricted axial access, add the installation dimensions. The final order drawing should resolve these interfaces before production.
Batch Planning
For NM 112 batches, separate standard dimensional matching from special-process requirements. Mixed models can be combined commercially, but a unique coating, heat-related request or inspection plan can impose its own process minimum. State those conditions at quotation stage.
よくある質問
What makes NM 112 a mid-size review point?
Its reference bore range reaches 48 mm while the supplied speed ceiling is 6000 rpm. It can therefore be a useful comparison size, but the real duty still controls selection.
Does VFD operation need to be mentioned?
Yes when the drive ramps, cycles or changes speed frequently. State the operating profile so the review is not based only on motor nameplate power.
Which installation dimensions should be approved?
Confirm both bores and keys, hub axial positions, required gap/spacing and any guard or shaft-shoulder restriction before manufacturing.
Can OEM identification be specified?
Project marking can be evaluated together with bore and finish requirements. Functional dimensions should be finalized before cosmetic or packaging details.
