About the Airtac SAID40 Double Rod Cylinder SAID40AX700
The AirTAC SAID40X700 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because a piston rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 528 N of force in both extend and retract directions at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance compared to a single-rod SAI.
This specific configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. You can mount a workpiece on the front rod end while attaching a position flag or cam to the rear protrusion to trigger external sensors.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX700 Is Used
Symmetric Force Transfer
Drives loads requiring identical push and pull dynamics, utilizing the 528 N both-way output to ensure consistent speed and force during bidirectional material handling.
Anti-Rotation Slides
Leverages the dual-rod guidance to prevent mechanical twisting on long 700 mm strokes, maintaining precise linear tracking without external linear bearings.
Rear-End Cam Actuation
Uses the protruding rear rod to operate mechanical valves or physical limit switches, sequencing secondary operations independently from the primary front-side tooling.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX700 the Right Cylinder?
Choose this 40 mm bore when an application demands equal push and pull forces—such as 528 N at 0.5 MPa—across a 700 mm travel. If your mechanism requires less force, stepping down to the 32 mm bore provides 345 N both ways, whereas the 50 mm bore offers 825 N for heavier loads. The twin-rod design is selected over a single-rod cylinder when you need dual-side guidance to prevent torsional twist or require a rear rod end for secondary mechanism timing.
With a 700 mm stroke, the unsupported rod length increases susceptibility to bending under side loads; always use an external guide rail to support the payload. Note that a standard SAID does not hold position upon air loss—integrate an external pilot-operated check valve if static locking is required. For drop-in replacements, verify the ISO 15552 mounting dimensions, the PT G1/4 port, and your chosen mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2).

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID40 Double Rod Cylinder SAID40AX700 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It generates 528 N of force in both the extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID40X700 is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 double-rod profile cylinders by matching the G1/4 port and standard mounting dimensions.
