The FA series of chucks features a stationary air distributor ring, incorporating special profile seals and locking check valves to maintain air pressure while the chuck is rotating. Standard repeating accuracy is 0.0001" (0.002-mm) TIR.
In addition, the chucks are available with the QC precision jaw locating system. The system maintains 0.0002" (0.005 mm) maximum workpiece runout after jaw change without remachining top jaws. It also enables the interchangeability of finished machined jaws between different chucks while maintaining maximum workpiece runout within 0.0008" (0.02 mm).
The chucks are available in three- and two-jaw configurations in the following sizes: 6" (150-mm) diameter with 1.33" (34-mm) through-hole; 8" (200-mm) diameter with 2" (51-mm) through-hole; and 10" (250-mm) diameter with 3" (77-mm) through-hole.
