About the Airtac SAID40 Double Rod Cylinder SAID40X160
The AirTAC SAID40X160 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 160mm stroke. Because a carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 528N output force each way at 0.5 MPa (739N at 0.7 MPa).
This through-rod architecture allows driving a primary workpiece on one end while mounting a cam or position flag on the rear rod for external tracking. The extruded aluminum barrel includes sensor grooves on both sides, and the standard PT G1/4 porting pairs with adjustable air cushions at both ends to manage kinetic energy.

Where the Airtac SAID40 Double Rod Cylinder SAID40X160 Is Used
Symmetric Force Transfer
Drives loads back and forth with exactly 528N of thrust in both directions, ensuring consistent cycle timing without pressure compensation.
Anti-Rotation Slides
The twin carbon steel rods prevent piston rotation, providing precise linear guidance for external tools and fixtures.
Through-Rod Sensing
Mounts a cam or target on the rear rod end to trigger external proximity sensors without interfering with the primary work area.
Is the Airtac SAID40 Double Rod Cylinder SAID40X160 the Right Cylinder?
Select this 40mm bore when an application requires 528N of symmetric force both directions, or step down to a 32mm bore (345N) for lighter loads. Step up to a 50mm bore (825N) if your mechanism needs greater thrust. The twin-rod design is chosen over a single-rod SAI when dual-side guidance, anti-rotation stability, or rear-rod actuation is required.
Being dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders. Ensure you specify the PT port thread, appropriate mounting from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2), and note that a plain SAID does not hold loads without live air pressure—consider SAIL or BSAID variants if locking is needed. For this 160mm stroke, side-load is minimal, but longer unsupported strokes require an external guide.
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 SAID40X160 FAQ
Because the double-rod design subtracts the rod area on both sides, the extend and retract forces are equal. It provides 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa in both directions.
Yes. The SAID40X160 is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other standard double-rod profile cylinders, utilizing a G1/4 PT port and an extruded aluminum barrel.
