About the Airtac SAID160 Double Rod Cylinder SAID160AX155
The AirTAC SAID160X155 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 160 mm bore and 155 mm stroke. Because the piston rod exits both ends, the annulus area is identical on both sides, yielding an equal extend and retract force of 9425 N at 0.5 MPa. This symmetric thrust is ideal for mechanisms demanding consistent power and velocity in both directions of travel.
This specific unit is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The rear rod protrusion allows engineers to mount a cam, position flag, or secondary mechanism on the opposite side, providing dual-side guidance and superior anti-rotation control compared to single-rod alternatives.

Where the Airtac SAID160 Double Rod Cylinder SAID160AX155 Is Used
Anti-Rotation Slides
The twin-rod design prevents piston rotation, making it perfect for precision lifting slides where load leveling and strict guidance are critical.
Symmetric Force Transfer
Provides identical 9425 N force and speed in both directions, ensuring balanced and stable actuation for heavy symmetric transfer mechanisms.
Dual-Station Actuation
Mount a workpiece on the front rod and a secondary cam or sensor flag on the rear rod to drive or monitor two separate stations simultaneously.
Is the Airtac SAID160 Double Rod Cylinder SAID160AX155 the Right Cylinder?
Selecting this 160 mm bore is appropriate when applications require substantial symmetric thrust (9425 N at 0.5 MPa) that a smaller 125 mm bore (5734 N) cannot provide. The double-rod architecture is chosen over a single-rod SAI when the load must be guided against rotation or when a rear-mounted position flag is needed for external sensing. Since this is a plain double-rod cylinder, it does not hold its position if air pressure is lost; for dead-load holding, consider an AirTAC SAIL or BSAID variant. Ensure you specify the PT port thread, SUS420J2 rod material, and appropriate mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2) for your ISO 15552 drop-in replacement.
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 SAID160 Double Rod Cylinder SAID160AX155 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It provides an equal extend and retract force of 9425 N at 0.5 MPa, and 13194 N at 0.7 MPa.
Yes, the SAID160X155 is dimensionally interchangeable per ISO 15552 standards. It can serve as a drop-in replacement for other ISO 15552 double-rod profile cylinders, utilizing the same mounting interface.
