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.
