About the Airtac SAID80 Double Rod Cylinder SAID80BX250
The AirTAC SAID80X250 is a double-acting, double-rod ISO 15552 profile cylinder engineered for applications demanding equal force and speed in both directions. Because a rod exits both ends, the effective piston area is symmetrical, delivering 2268N of thrust and pull at 0.5MPa. This through-rod architecture provides superior anti-rotation guidance compared to a single-rod SAI.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount position switches independently on either end as your layout requires.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX250 Is Used
Symmetric Force Transfer
Drives a workpiece on the front stroke while simultaneously operating a secondary cam or flag on the rear rod, ensuring perfectly synchronized motion.
Anti-Rotation Slides
The twin-rod design resists torsional twisting under offset loads, providing stable linear guidance for precision sliding mechanisms.
Twin-Station Actuation
Mounts a tool on one end and a position flag on the other, allowing independent sensor tracking of the extend and retract cycles.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX250 the Right Cylinder?
Select this 80mm bore when an application requires moving identical loads on both the extend and retract strokes, or when you need to drive a secondary mechanism via the rear rod. If your force requirements are lower, stepping down to a 63mm bore yields 1402N at 0.5MPa. For higher throughput, the 100mm bore offers 3681N.
With a 250mm stroke, the unsupported rod length increases; you should use an external guide to prevent side-load bending at the rod bearing. Remember that standard air cushions only decelerate the piston near stroke end and do not hold the load if air pressure drops. For position holding without live pressure, consider a BSAID clamp-lock variant. This model is dimensionally interchangeable per ISO 15552.
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 SAID80 Double Rod Cylinder SAID80BX250 FAQ
Because it is a double-rod cylinder, the extend and retract forces are identical. It outputs 2268N in both directions at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, the SAID80X250 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and features a G3/8 port.
