Two independent wedge drives Operated by independent double piston cylinders. Jaws 2 and 4 are power operated to center the component in one axis and to drive the component. Jaws 1 and 3 are power operated to center the component on the second axis and to drive the component. Since both pairs of jaws are power operated the chuck can reach high speeds. See specific draw pull, gripping force and maximum speed in the technical data table below.
