The Airtac Large Bore Opening Clamp Cylinder Series
The Airtac Large Bore Opening Clamp Cylinder is a robust and efficient pneumatic clamping actuator designed for heavy-duty automation systems, welding fixtures, and industrial assembly equipment.

Featuring a large bore design and a wide opening angle, this cylinder provides exceptionally high clamping force and stable performance in demanding environments like automotive manufacturing and robotic gripping.

🔹 Product Overview
The Airtac Large Bore Clamp Cylinder combines precision clamping control with high output power. Its jaws are driven by a double-acting mechanism, allowing rapid motion and a strong grip. Thanks to the advanced sealing structure, it maintains consistent performance even under high-frequency operation while saving installation space.

🔸 Key Features
• Large Bore Design: Provides powerful clamping force (up to 10,000 N) for heavy operations.
• Wide Opening Angle: Allows flexible access to workpieces (up to 135°).
• Double-Acting Structure: Ensures smooth and rapid opening/closing cycles.
• Durable Construction: High-strength aluminum alloy body with precision-machined parts.
• Magnetic Switch Slots: Fully compatible with Airtac magnetic sensors for position feedback.
• ISO Interchangeability: Equivalent to SMC CK / CKZ2 series and Festo clamp cylinders.
