Hydraulic Stationary Power Chuck is a non-rotating, hydraulically actuated jaw-type chuck engineered for very high and consistent clamping force with dead-length accuracy (no axial movement of the component during clamping).
Because the chuck body remains stationary, it delivers maximum rigidity, safety, and repeatability, making it ideal for CNC stationary operations, SPMs, transfer lines, and automated production cells.
This chuck is preferred for heavy machining, hard materials, and high-load applications where pneumatic stationary chucks are not sufficient.
Key Features
- • Hydraulic Actuation (High & Constant Clamping Force)

- • Jaw Type Power Chuck (3-Jaw Standard, 4-Jaw Optional)
- • Hardened & Ground Alloy Steel Construction
- • Fast Clamp–Unclamp (Automation Ready)
- • Long Service Life & Low Maintenance
- • Sealed Against Chips & Coolant
