Rotating air chucks are ideal for precision turning and cylindrical grinding applications that require close concentricity, squareness, and parallelism tolerances. Variable clamping force enables clamping of thin-walled and other fragile parts with minimal distortion. All models, except the 3-50, feature a coolant or air passage through the center of the chuck.

Chuck Accuracy

  • .00005" (0.0012mm) TIR is standard

  • 1 2 jaw configurations available for all air chuck sizes, 6 jaw configurations available on 10 inch (250 mm) models
  • 2 Chuck accuracy is defined as the total indicator reading (maximum radial and lateral runout) of a master gage measured 1.0" (25 mm) from the face of a standard top jaw
  • 3 Total jaw stroke (on diameter)
  • 4 Max. rpm is influenced by air pressure and mass of top jaws
