Product Overview
A Pneumatic Rotary Collet Chuck is an air-operated, rotating work holding device designed for fast, accurate, and repeatable clamping in CNC lathes, turning centers, and automation lines.
It delivers uniform 360° gripping, enabling high spindle speeds, reduced setup time, and consistent part quality—ideal for mass production.
Key Advantages
⚡ Fast clamping/unclamping with compressed air
🎯 High concentricity & repeat accuracy
🔄 Rotary design for high-speed machining
🧩 Interchangeable collets (ER / 5C / Traub / Special)
🤖 Automation-ready (robots, gantries, bar feeders)
🛠️ Low maintenance, long service life
Working Principle
Compressed air enters the chuck body
Internal piston actuates the draw mechanism
Collet closes uniformly on the job
Air release opens the collet instantly
Result: reliable, repeatable clamping every cycle.

A Front Mounted Pneumatic Power Chuck is a compact, space-saving air-operated chuck that mounts directly on the spindle nose from the front side. With an integrated pneumatic cylinder, it provides high clamping force, fast response, and reliable repeatability, making it ideal for CNC lathes, turning centers, and automated production setups where rear access is limited or quick installation is required.
A Pneumatic Rotary Power Chuck is a heavy-duty, air-operated workholding system designed for continuous rotation and high clamping force. Featuring a built-in pneumatic cylinder, it is ideal for CNC lathes, rotary tables, and 4-axis/5-axis machines requiring jaw-type gripping, automation compatibility, and reliable performance in high-speed production environments.
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.
