Selection of FLUDEX type
Listed in the catalog are FLUDEX couplings with pulley, brake
drum, brake disk and flexible N-EUPEX coupling.
Further types, e.g. in combination with a torsionally rigid steel
membrane coupling of the ARPEX series or a highly flexible cou-
pling of the ELPEX or ELPEX-S series, are available.
The maximum shaft misalignments permissible for an N-EUPEX
add-on coupling are shown in catalog section 7. For greater
shaft misalignments FLUDEX couplings can be combined with
cardan shafts or other displacement couplings.
