FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings — ARPEX ARC-8/-10 Series
6/31
Siemens MD 10.1 · 2015
Types NEN/NHN
6
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 = S min.
Permitted shaft distance S of type NHN relative to speed
Ordering example:
ARPEX ARC-8 NHN coupling, size 270-8, with shaft distance
S = 1000 mm,
Bore
∅
D1 120H7 mm, with keyway to DIN 6885 and set screw,
Bore
∅
D2 130K7 mm, with keyway to DIN 6885 and set screw.
