Small Hydraulic Stationary Collet Chuck is a compact, non-rotating, hydraulically actuated workholding unit engineered for small components and limited installation space. It delivers high and consistent clamping force with dead-length accuracy (no axial movement during clamp/unclamp), making it ideal for precision machining, secondary operations, and automated cells.
Designed to reduce footprint without compromising rigidity, this chuck supports small collet systems and maintains excellent concentricity for fine finishes.
