FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARC-8/-10 Series © Siemens AG 2015 Types MFEFM/MFHFM 6 FEF or FHF transmission unit preassembled at the factory enables easy final assembly by the customer. In the case of individual order of the intermediate spacer, the length (LZ) must be specified. 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. Permitted shaft distance S of type MFHFM relative to speed Ordering example:
ARPEX ARC-8 MFHFM coupling, size 270-8, with shaft distance S = 1000 mm, Bore ∅ D1 150H7 mm, with keyway to DIN 6885 and set screw, Bore ∅ D2 160K7 mm, with keyway to DIN 6885 and set screw.
