Airtac QCK: Clamping Air Cylinder - QCKL25X20S  Air Clamp Actuator

Pneumatic rotary clamp cylinder, push and turn left, 25mm bore, 20mm clamping stroke, with magnet, no mounting typeCompared to the SMC MK series, The AirTac QCK clamping air cylinder series is a functional replacement.

Product Features:

1.It can be used on welding fixture, the QPQ surface treatment prevent piston rod damage by welding slag; better than chrome plated piston rod.
2.The front cover with stainless steel dust scraping ring, can keep the dust and welding slag out, and protect cylinder internal parts.
3.Strong magnet is optioned for 32mm to 63mm bore size, which can be used in high magnetic fields.
4.The mounting dimension of body is the same as ACQ series. ACQ series accessories can be used.




The Airtac Rotary Clamp Cylinder Series
The Airtac Rotary Clamp Cylinder is a high-performance pneumatic clamping actuator that combines rotary motion and clamping function in one compact unit.

Designed for industrial automation and welding jigs, it rotates the clamp arm by a specific angle (typically 90° or 180°) and then performs a powerful clamping motion. This two-in-one design simplifies automation layouts and improves productivity.

🔹 Product Overview
Airtac’s advanced pneumatic sealing technology ensures smooth rotation and long lifespan even under continuous high-frequency operation. The compact design saves installation space in robotic fixtures, while providing high torque output for firm gripping of heavy workpieces.

🔸 Key Features
• Rotary + Clamp Function: Combines rotation and linear clamping in one pneumatic unit.
• Adjustable Rotation Angle: Standard versions include 90°, 120°, and 180° options.
• Double-Acting Structure: Stable clamping and easy release controlled by air pressure.
• Durable Construction: Anodized aluminum housing and hardened steel internal mechanism.
• Sensor Compatibility: Magnetic switch slots for real-time position detection.
• Standard Compatibility: Interchangeable with SMC CKQ series and Festo DRRD series.
