    FAQ

    • What exactly does "free mounting" or "multi-surface direct mounting" mean for the ACU series cylinders? What are the advantages?

      "Free mounting" refers to the cylinder's unique square body design, which allows for direct mounting on the top, bottom, or side of the body without the need for additional mounting brackets. This design significantly reduces equipment space and provides exceptional mounting flexibility, allowing engineers to freely select the mounting surface based on the optimal mechanical layout, simplifying design and reducing overall costs.
    • What's the difference between "ACU" and "ACDU" in the product model?

      The ACU is a standard, free-mount cylinder. The ACDU, on the other hand, is a cylinder with a built-in magnetic switch. A magnetic ring is embedded in the cylinder body, allowing for the installation of a magnetic switch (proximity sensor) to detect piston position. The ACDU model allows users to directly purchase a cylinder with a sensor function, simplifying the purchasing and assembly process.
