Hydraulic Stationary Collet Chuck with Head is a non-rotating, hydraulically actuated workholding unit supplied with an integrated chuck head / mounting head. The head allows direct mounting on CNC machines, SPMs, transfer lines, or fixture plates without additional adapters, ensuring maximum rigidity and alignment accuracy.
This chuck operates on a dead-length pull-back principle, providing zero axial movement during clamping and very high, consistent gripping force, making it ideal for precision OD clamping in heavy-duty and automated machining.
Supported collet systems include 5C, YB (16YB / 25YB / 40YB), Traub (A25 / A42 / A60), Thada, and special job-specific collets.
π Key Features
- π§ Hydraulic Actuation (High & Constant Clamping Force)
- π§± Stationary / Non-Rotating Body
- π§© Integrated Mounting Head (Rigid One-Piece Design)
- π― Dead-Length Clamping (Zero Axial Shift)
- βοΈ Supports 5C / YB / Traub / Thada / Special Collets
- π© Uniform 360° OD Grip
- π οΈ Hardened & Ground Alloy Steel Construction
