Selection and ordering data
The hub diameter of the component part is assigned according
to the diameter of the finished bore. 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.
