A Pneumatic Expanding Stationary Collet Chuck is a non-rotating, air-operated internal workholding system that grips components from the inside diameter using an expanding collet. With dead-length clamping and zero axial movement, it is ideal for thin-wall parts, rings, sleeves, bushes, and bearing housings in CNC stationary operations, SPMs, transfer lines, and automated production systems requiring high accuracy and repeatability.
Pneumatic Expanding Stationary Collet Chuck is a non-rotating, air-operated internal clamping system designed to grip components from the inside diameter (ID) using an expanding collet.
Its dead-length design ensures zero axial movement during clamping, making it ideal for thin-wall parts, rings, sleeves, bushes, and bearing housings where external clamping may cause deformation.
This chuck is widely used in CNC stationary operations, SPMs, transfer lines, and automated production systems requiring high accuracy and repeatability.

A Multiple OD Clamping Collet Chuck – Pneumatic Stationary is a non-rotating, air-operated workholding system designed to clamp multiple components simultaneously on their outside diameter. Using stationary pull-back collet modules with dead-length accuracy, it provides uniform gripping, excellent repeatability, and increased output per cycle, making it ideal for SPMs, transfer lines, CNC stationary operations, and automated production cells.
A VMC Pneumatic Multiple Clamping Fixture is a custom-designed, air-operated workholding system that clamps multiple components simultaneously on a Vertical Machining Center. It reduces loading time, increases spindle utilization, and ensures consistent part-to-part accuracy, making it ideal for mass production, batch machining, and automation-ready CNC environments.
A Mini Air Collet Chuck is a compact, air-operated workholding solution designed for small-diameter components and precision machining. It provides fast clamp–unclamp cycles, uniform gripping, and excellent repeatability, making it ideal for CNC lathes, bench machines, SPMs, and automation stations handling micro parts, medical, electronic, and fine engineering components.
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.
A Pneumatic Stationary Chuck is a non-rotating, air-operated workholding system that provides dead-length clamping with no axial movement, high rigidity, and repeatable accuracy. Its stationary design ensures stable and consistent part positioning, making it ideal for CNC stationary operations, SPMs, transfer lines, and automated cells, and it is available in jaw, collet, Traub collet, and expanding collet configurations.
A Pneumatic Stationary Power Chuck is a non-rotating, air-operated workholding system designed to deliver high clamping force with dead-length accuracy and maximum rigidity. Its stationary design ensures zero axial movement, consistent part positioning, and fast cycle times, making it ideal for CNC stationary setups, SPMs, transfer lines, and automated production cells requiring reliable and repeatable performance.
A Pneumatic Stationary Power Chuck with Head is a non-rotating workholding system that uses compressed air to actuate jaws through an integrated power head mechanism. It delivers high clamping force, dead-length performance with zero axial shift, and consistent repeatability, making it ideal for CNC stationary fixtures, SPMs, transfer lines, and automated production systems requiring strong grip and reliable performance under demanding machining conditions.
A Pneumatic Stationary Traub Collet Chuck is a non-rotating, air-operated workholding system designed for Traub collets and dead-length clamping.
