Pneumatic Stationary Pull Back Collet Chuck is a non-rotating, air-operated workholding system designed to work with 5C, 16YB, 25YB, 40YB, and Thada collets.
The chuck operates on a pull-back mechanism, where compressed air pulls the collet backward into a hardened taper, generating strong radial clamping force.
This design ensures dead-length clamping, meaning no axial movement of the job, making it ideal for high-precision CNC stationary operations, SPMs, and automation lines.
Key Features
- • Pneumatic Pull-Back Actuation
- • Stationary / Non-Rotating Body
- • Dead-Length Clamping (Zero Job Movement)
- • High Gripping Force with Uniform Pressure
- • Supports 5C / 16YB / 25YB / 40YB / Thada Collets
- • Hardened & Ground Alloy Steel Construction
- • Fast Clamp–Unclamp Cycle
- • Low Maintenance, Long Service Life
