NEH Series: Large-Size Spacer Type Couplings
NEH Series large-size Spacer Type couplings can be used for applications up to176400 N·m {18000 kgf·m}.
Note: The disk set is comprised of a disk, bush and collar. (See p. 5)
Unit:
mm
Notes 1. All sizes are custom-made.
2. The maximum rotation speed depends on the transmission capacity of the coupling.
No balance adjustment has been conducted. Contact us to adjust the balance for couplings at a high rotation speed.
3. The weight, moment of inertia and GD 2 are the values at maximum bore diameter (keyway).
4. Spacer lengths other than the standard length can be also manufactured. For details on the long spacer type, see p. 17.
5. The allowable axial displacement is based on the assumption that the angular misalignment is “0”.
6. Check the key surface pressure in accordance with your operating conditions (see p. 18). The hub material is S45C.
