Selection and ordering data
Torsionally rigid coupling type NZN with variable shaft distance S and reinforced intermediate spacer.
Type NZN 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.
Weights and mass moments of inertia apply to the entire
coupling with maximum bores D1/D2 and S = 1000 mm.
