About the Airtac SAID100 Double Rod Cylinder SAID100BX40S
The AirTAC SAID100X40-S is a double-acting, double-rod profile cylinder that strictly conforms to ISO 15552 dimensional interchangeability. A single piston drives a rod out of both end covers, yielding an identical annulus area on the extend and retract sides. Consequently, it generates an equal 3681 N of thrust and pull force at 0.5 MPa, ensuring perfectly symmetric motion speeds.
This specific unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a piston magnet (-S) for position detection. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches along either rod extension. It uses PT tapered port threads and offers adjustable air cushioning at both ends to soften end-of-stroke impacts.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX40S Is Used
Symmetric Force Transfer
Drives a heavy workpiece back and forth with exactly 3681 N of force in both directions, preventing speed variations between extend and retract cycles.
Twin-Station Actuation
Mounts a primary tool on the front rod extension and a secondary mechanism or cam on the rear rod end to operate two synchronized stations from one actuator.
Anti-Rotation Slides
Uses the dual-rod geometry to guide a heavy vertical slide, preventing torsional twist and maintaining precise linear tracking without external guides.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX40S the Right Cylinder?
Choose this 100 mm bore over the 80 mm version (which provides 2268 N each way at 0.5 MPa) when your mechanism requires higher symmetric force, or step down to the 125 mm bore (5734 N) if you need extreme push-pull capacity. The twin-rod architecture is specifically selected over a single-rod SAI when the application demands dual-side guidance to prevent rotation, or when a rear cam and position flag must trigger a sensor while the front rod executes the primary work.
For a 40 mm stroke, side-load bending is minimal, but always verify the rod bearing can handle any off-center loads. Remember that a standard SAID does not hold its position if air pressure is lost; the piston will drift. If your setup requires dead-stop load holding without live pressure, consider an AirTAC SAIL pneumatic lock or an external pilot-operated check valve. This cylinder is a drop-in replacement for any ISO 15552 double-rod footprint and accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAID100 Double Rod Cylinder SAID100BX40S FAQ
Because the double-rod design has the same annulus area on both sides, it delivers equal force in both directions. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes. The SAID100X40-S is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses PT ports and accepts standard SAID mounting accessories like FA, LB, and TC.
