Where bore diameters over- lap, the component with the smaller hub diameter is always se- lected. Weights and mass moments of inertia apply to cast iron version with maximum bore. From size 500, the bores D1 and D2 are each provided with a recess of D = +1 mm halfway along the hub. V ≈ 1/3 NL Notice:
The application factor FB in the coupling selection section must be noted. Ordering example: ELPEX EFG coupling, size 430, steel version, bore ∅ D1 = 100H7 mm with keyway to DIN 6885 and set screw, flange to SAE J620d size 21 with DFA = 673.5g7 mm. Coupling balanced G6.3 in accordance with the half parallel key stan- dard.
