■
Selection and ordering data
Torsionally rigid couplings of type NEN with radially freely dismountable intermediate spacer and fly-away prevention for securing
the intermediate spacer if a plate breaks.
Standard coupling design in accordance with API 610. Coupling design in accordance with API 671 (up to n = 1800 rpm) possible.
Hubs are designed with threaded pull-off holes.
Special lengths available on request.
The total lengths, the weights, and the mass moments of inertia
apply to the entire coupling with maximum bores D1/D2 and the
preferred shaft distance S.
Ordering example:
N-ARPEX coupling ARN-6 NEN, size 217-6, with shaft
distance S = 140 mm (
2LC0370-8AA99-0AB0
),
Bore ØD1 50H7 mm, with keyway to DIN 6885-1 and set screw
(
