Jaws 2 and 4 are spring operated to center the component in one axis. Jaws 1 and 3 are power operated by the cylinder to center the component on the second axis and to apply the gripping force to drive the component. Only for external clamping (on request internal clamping). See specific draw pull, gripping force and maximum speed in the technical data table below. Technical data B Two independent wedge drives* Operated by independent double piston cylinders. Jaws 2 and 4 are power operated (using the small cylinder) to center the component in one axis. Jaws 1 and 3 are also power operated (using the large cylinder) to center the component on the second axis and to apply the gripping force to drive the component. Since both pair of jaws are power operated the chuck can reach higher speeds. See specific draw pull, gripping force and maximum speed in the technical data table below. *Note: The chucks are always delivered as „one wedge drive“ version: To use them as „two independent wedge drives“ version, just remove the internal spring assembly according to instruction manual A ONE wedge drive B TWO independent wedge drives ** For internal clamping reduce the draw pull by 30%.
