FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARC-8/-10 Series © Siemens AG 2015 Types NEN/NHN 6 The permitted length of the intermediate spacer depends on the maximum operating speed of the coupling (see following table). Weights and mass moments of inertia apply to the entire coupling with maximum bores D1/D2 and S = S min. In the case of individual order of the intermediate spacer, the length (LZ) must be specified. 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.
