Northfield Precision Instrument Corp. introduces the Model 650 Sliding Jaw air chuck. This air chuck, with 0.0001" TIR, has special quick-change jaws and a hard stop.
This particular custom-made chuck was made for a customer who manufactures output gears and needed to grip on the interior diameter. Subjaws are permanently mounted to the chuck's master jaws. Quick-Change top jaws are held in place by one bolt through a keyhole slot in each jaw pad.
