Large Diameter Air Chucks offer high accuracy and adjustable clamping force for machining large diameter precision and thin-walled workpieces. Large Diameter chucks are availalbe in three jaw as well as two and six jaw configurations. Large Diameter models with extended jaw stroke, air ports on OD of chuck body for stationary applications, and other special configurations are quoted upon request.

Chuck Accuracy

  • .0002" (0.005mm) TIR is standard
  • .0001" (0.0025mm) TIR is available
