Hydraulic Stationary Chuck is a non-rotating, hydraulically actuated workholding system designed to deliver very high and consistent clamping force with dead-length accuracy—meaning no axial movement of the component during clamping.
Because the chuck body remains stationary, it offers maximum rigidity, safety, and repeatability, making it ideal for CNC stationary operations, SPMs, transfer lines, and automated production systems.
Hydraulic stationary chucks are preferred where heavy machining, hard materials, and high load stability are required.
