Listed in the catalog are FLUDEX couplings with pulley, brake drum, brake disk and flexible N-EUPEX coupling. FLUDEX couplings designed specifically for operation with water/water emulsion are available for use inmining applications. The maximum shaft misalignments permissible for an N-EUPEX add-on coupling are shown in catalogue https://www.jbj.co.uk/e-publications/N-Eupextorsionally-flexible-couplings-available-from-jbj-Techniques-Limited/8/index.html For greater shaft misalignments FLUDEX couplings can be combined with cardan shafts or other displacement couplings.
