Airtac SAID40 Double Rod Cylinder SAID40BX110S
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40BX110S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 110mm 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 SAID40BX110S
The AirTAC SAID40X110-S is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions. It generates 528 N each way at 0.5 MPa and 739 N at 0.7 MPa.
Equipped with a magnet (-S) for CMSE reed and DMSE solid-state sensors, it features dual-side sensor grooves on the extruded aluminum barrel. The SUS304 stainless steel rods (code B) provide excellent corrosion resistance, and the PT tapered port threads ensure a reliable pneumatic seal.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX110S Is Used
Symmetric Force Transfer
Drives a push-pull transfer mechanism where equal 528 N force in both directions prevents imbalanced loading on the conveyor line.
Anti-Rotation Slides
The twin SUS304 rods guide the load against rotation without external guide rails, ideal for precision vertical lifting slides.
Through-Rod Sensing
Mounts the primary tool on the front rod and a DMSE sensor flag on the rear rod to confirm full stroke position from the back cover.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX110S the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (345 N at 0.5 MPa) lacks sufficient thrust for symmetric transfer, but a 50 mm bore (825 N) would be excessive. The twin-rod design is selected over a single-rod SAI when the application requires dual-side guidance, anti-rotation stability, or mounting a rear cam and position flag alongside the primary workpiece.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard profile double-rod actuators. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB/CA/CB/CR). Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. For position holding without live pressure, use an external rod lock or explore SAIL or BSAID variants.
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 SAID40BX110S FAQ
It provides 528 N of force in both extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa. Because it is a double-rod cylinder, the push and pull forces are identical.
No, the SAID40X110-S is a standard double-acting cylinder. Its adjustable air cushions only decelerate the piston at stroke end and do not function as a locking mechanism. For load holding, consider the SAIL or BSAID series.
