A Pneumatic Rotary Expanding Collet Chuck is a power-operated internal gripping workholding system that uses compressed air for automatic clamping during continuous rotation. The expanding collet grips components from the inside diameter with low distortion, making it ideal for thin-wall parts, rings, bushes, and bearing housings in CNC lathes, rotary tables, and 4-axis/5-axis machining applications.

A Pneumatic Rotary Jaw Type Chuck is an air-operated, rotating workholding chuck used on CNC lathes and turning centers for fast, accurate, and repeatable clamping. Actuated via compressed air through a rotary union, it supports 2-jaw, 3-jaw, or 4-jaw configurations and is ideal for high-speed, automated production where short cycle times are critical.
A Pneumatic Rotary Collet Chuck is an air-operated, rotating workholding device designed for fast, accurate, and repeatable clamping in CNC lathes, turning centers, and automated production lines. It provides uniform 360° gripping, supports high spindle speeds, reduces setup time, and ensures consistent part quality for mass production applications.
