Selection and ordering data
Torsionally rigid type NHN coupling with high angular misalignment capacity up to 3° and radially freely dismountable intermediate
spacer and variable shaft distance S.
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.
Mass moments of inertia and weights apply to the entire NHN
coupling with maximum bores D1/D2 and a shaft distance
S = S min.
