Airtac SAID40 Double Rod Cylinder SAID40AX700S
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40AX700S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 700mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID40 Double Rod Cylinder SAID40AX700S
The AirTAC SAID40X700-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding an equal extend and retract force of 528 N at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance and allows a secondary mechanism or position flag to be driven from the rear.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. The rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and it features adjustable air cushioning at both ends to decelerate the mass smoothly over its 700 mm travel.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX700S Is Used
Symmetric Force Transfer
Drives a workpiece from one end while moving a counterweight or secondary tool on the rear rod end, maintaining perfectly balanced 528 N force in both directions.
Anti-Rotation Slides
Utilizes the twin-rod structure to guide vertical lifting slides over the 700 mm stroke, preventing torsional twist without external linear bearings.
Through-Rod Sensing
Mounts a physical cam or limit flag on the rear protruding rod to trigger DMSE electronic sensors, providing a secondary confirmation independent of the main piston magnet.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX700S the Right Cylinder?
Select this 40 mm bore when an application demands matched push and pull forces that a single-rod SAI cannot provide, stepping up from a 32 mm bore (345 N both ways) or down from a 50 mm bore (825 N both ways). The 700 mm stroke operates within the standard 1200 mm limit for this bore, but the lengthy travel combined with a 16 mm rod requires careful attention to side-load and rod-bearing bending; an external guide is highly recommended to prevent premature seal wear. Remember that the adjustable cushion only decelerates the piston near stroke end and does not hold the load if air pressure is lost.
For a drop-in replacement, ensure the ISO 15552 mounting dimensions match your existing footprint. This model uses a PT tapered port thread and is compatible with the SAID mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). If pneumatic locking is required for safety, consider the SAIL or BSAID variants instead.
Quick checklist
- ✓ 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 SAID40AX700S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal force of 528 N in both extend and retract directions at 0.5 MPa (739 N at 0.7 MPa).
Yes, the SAID40X700-S is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other standard profile double-rod cylinders, provided your mounting accessory is within the Basic, FA, LB, TC, FTC, TCM1, or TCM2 set.
