Selection and ordering data
Torsionally rigid coupling type NHN with variable shaft distance S. Type NHN with radially freely dismountable intermediate spacer.
The permitted length of the intermediate spacer depends on the
maximum operating speed of the coupling
(see following table).
In the case of individual order of the intermediate spacer, the
length (LZ) must be specified.
For greater shaft distances,
see type NZN.
Weights and mass moments of inertia apply to the entire
coupling with maximum bores D1/D2 and S = 1000 mm.
