AirTAC Type SU Series: High-Performance Internal Tie-Rod Standard Cylinder

The AirTAC SU series is a signature standard cylinder recognized for its robust performance and clean aesthetic. Unlike traditional cylinders with exposed rods, the SU series features an internal tie-rod design, which hides the tension rods within the profile. This not only provides a smooth, easy-to-clean surface but also enhances the structural integrity of the cylinder.


Key Technical Features & Highlights

  • Adjustable Air Cushioning: Equipped with adjustable cushions at both the front and rear caps, ensuring the cylinder runs smoothly, safely, and without loud impact noise.

  • Non-Lubricated Design: The high-quality seals and self-lubricating bearings allow the cylinder to operate without additional oil lubrication, perfect for clean environments.

  • Durable Construction: Built with a high-strength aluminum alloy barrel and a hard-chromed carbon steel piston rod (stainless steel available) for superior wear and corrosion resistance.

  • Multiple Mounting Options: Compatible with various AirTAC standard accessories, including FA, FB, CA, CB, LB, and Y-joints.
