    [Note] 1. Please contact us for other special strokes.
                2. Non-standard strokes within the maximum stroke range are modified from the next higher standard stroke. Their dimensions are the same as the next higher standard stroke. For example, a non-standard stroke cylinder with a stroke of 23 is modified from a standard cylinder with a stroke of 25 and has the same dimensions.

    FAQ

    • What exactly does "free mounting" mean for the AMU series cylinders?

      "Free mounting" means the AMU series cylinders offer extremely flexible mounting options. They can be mounted from four different positions: axially forward, axially rearward, lateral to the left, or lateral to the right. This design allows them to easily fit into a variety of compact and complex installation spaces without the need for additional adapters, greatly simplifying mechanical design.

    • What is the difference between an AMU (double-acting) and an AMSU (single-acting)? How should I choose?

      The primary difference lies in the actuation method: AMU (double-acting): This uses compressed air to control both piston extension and retraction, offering high positioning accuracy and fast response. It is suitable for applications requiring precise control of reciprocating motion. AMSU (single-acting): This typically uses spring force to return the piston, with compressed air supplied through a single air port to extend the piston. This simpler design allows for automatic return to a safe position in the event of air loss. Suggested Selection: Choose an AMU if precise bidirectional control is required. For thrust applications requiring fail-safe reset or for lower costs, the AMSU is an ideal choice.
