PNEUMATIC STATIONARY COLLET CHUCK PULL BACK

A Pneumatic Stationary Pull Back Collet Chuck is a non-rotating, air-operated workholding system designed for 5C, YB (16YB, 25YB, 40YB), and Thada collets. Using a pull-back mechanism, compressed air draws the collet into a hardened taper to generate strong radial clamping with dead-length accuracy, ensuring no axial movement of the job—ideal for high-precision CNC stationary operations, SPMs, and automated production lines.

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.
