Pneumatic Stationary Power Chuck With Head is a non-rotating power chuck that uses compressed air to actuate jaws via a dedicated power head mechanism, delivering high clamping force, dead-length performance (zero axial shift), and consistent repeatability. This solution combines the strength of a power chuck head with the simplicity and speed of pneumatic actuation, making it ideal for CNC lathes (stationary fixtures), SPMs, transfer lines, and automated production systems.
The integrated power head drives all jaws simultaneously with robust mechanical leverage, giving superior torque and grip for demanding cut-and-hold conditions compared to basic pneumatic jaw systems.
