Pneumatic Chuck Diagram

1. Surface : Stainless steel surface keeps its high accuracy, easy to maintain and has blowing function for clean.
2. Positioning blocks : Positioning blocks are replacable and custom made is available for various of special workpieces machining.
3. Connecting structure : Patented piston connecting structure allows bigger deviation.
4. O-ring : High-quality seals, normal life expectancy is up to 5 years.
5. Spring : High-quality imported spring. Life expectancy is more than 1.2 million times. 200 times / day = 16 years.
6. Piston & Cylinder : All piston and cylinder are made of stainless steel. It won’t rust or stuck by moisture.

• All pneumatic chucks are with boost pressure function and can withstand the clamping force up to 280kgs.
• Link mechanism coated with special lubrication which won’t be deteriorated by moisture.
