A Hydraulic Stationary Expanding Collet Chuck is a non-rotating, hydraulically actuated internal workholding system that clamps components from the inside diameter with high and consistent force. Its dead-length design ensures zero axial movement, providing excellent concentricity and distortion-free holding, making it ideal for thin-wall rings, sleeves, bushes, and bearing housings in CNC stationary operations, SPMs, transfer lines, and automated production cells.
Hydraulic Stationary Expanding Collet Chuck is a non-rotating, hydraulically actuated internal clamping system designed to grip components from the inside diameter (ID) with very high and consistent force. Its dead-length design guarantees zero axial movement during clamping, delivering outstanding concentricity and distortion-free holding—ideal for thin-wall rings, sleeves, bushes, and bearing housings.
Best suited for CNC stationary operations, SPMs, transfer lines, and automated cells where rigidity and repeatability are critical.
