depressurized coupling, max. operating pressure 200 bar
radial misalignment of 2 mm is possible
no coupling stroke required
no protruding contours
compact dimensions
On machine centers with pallet changing systems, the coupling elements transfer hydraulic oil or compressed air from the machine table to the hydraulic clamping fixture. These automatically closing couplings have a flat surface and do not have protruding elements for sealing. Therefore exact positioning is not required and a radial positioning misalignment of up to 2 mm is admitted. Cleaning of the coupling surfaces is easily possible due to the flat surfaces.
