Pneumatic Stationary Power Chuck is a non-rotating, air-operated workholding solution designed to deliver high clamping force, dead-length accuracy, and maximum rigidity. Since the chuck body remains stationary, it eliminates centrifugal effects and provides consistent part positioning with zero axial movement during clamping.
This chuck is ideal for CNC lathes (stationary setups), special purpose machines (SPM), transfer lines, and automated production cells where reliability, repeatability, and fast cycle time are critical.
