Standard equipment
2+2 jaw chuck
1 set of T-nuts and bolts
1 set of soft top jaws
Mounting bolts
A One wedge drive B Two independent wedge drives*
Operated by standard closed center cylinders. Operated by independent double piston cylinders.
Jaws 2 and 4 are spring operated to center the component Jaws 2 and 4 are power operated (using the small cylinder)
in one axis to center the component in one axis
Jaws 1 and 3 are power operated from the cylinder to center Jaws 1 and 3 are also power operated (using the large
the component on the second axis and to apply the cylinder) to center the component on the second axis and
gripping force to drive the component. to apply the gripping force to drive the component.
Only for external clamping Since both pair of jaws are power operated the chuck can
See specic draw pull, gripping force and maximum speed reach higher speeds.

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.
