The permitted shaft misalignments ΔKa, ΔKr and ΔKw are maximum values and must not occur at the same time. The specified axial misalignments apply to the complete coupling. The permissible angular misalignments have been specified per coupling joint. As all N-ARPEX types are designed to be doublejointed, there is a direct interrelation between radial and angular misalignment.
