Model 4-120-3, Rotating Air Chucks

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
  • .00002" (0.0005mm) TIR is available
