ARPEXturbo couplings are allsteel couplings and can be supplied, inter alia, in the types shown in
figures 3 and 4. The plate packs are arranged in the fitted coupling modules between the flanges of the
coupling parts and bolted to them alternately. The ARPEX coupling is torsionresistant and transmits the
torque without circumferential backlash. In axial and radial direction the coupling is however still flexible
and can absorb axial, radial and angular misalignment of the coupled units.

The size designation of the coupling indicates the outside flange diameter DA (see fig. 3 and/or fig. 4) of
the coupling in mm. Attached item 6, 8, 10 or 12 (special version) specifies the number of
screwconnection points on the plate pack (see figure 5). This information is prefixed by a letter
combination specifying the component parts of the coupling.
