About the Airtac SAID80 Double Rod Cylinder SAID80X90
The AirTAC SAID80X90 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 90 mm stroke. Because a 25 mm rod exits both ends, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 2268 N at 0.5 MPa.
This through-rod design allows mounting the primary workpiece on one end while attaching a sensor flag or cam to the rear rod. The extruded aluminum barrel includes dual-side sensor grooves, and the standard carbon steel rod handles high side loads. It supports PT porting and adjustable air cushions at both ends.

Where the Airtac SAID80 Double Rod Cylinder SAID80X90 Is Used
Symmetric Force Transfer
Drives loads with equal 2268 N push and pull force, ensuring consistent speed and power during both extension and retraction strokes.
Anti-Rotation Slides
The twin-rod construction guides the load against rotation better than a single rod, ideal for precision sliding mechanisms.
Dual-Side Actuation
Mount a workpiece on the front rod and a cam or position flag on the rear rod to drive a secondary mechanism or sensor target.
Is the Airtac SAID80 Double Rod Cylinder SAID80X90 the Right Cylinder?
Choose this 80 mm bore when your application requires symmetric force and anti-rotation guidance that a single-rod SAI cannot provide. If you need less force, the 63 mm bore offers 1402 N at 0.5 MPa; for heavier loads, the 100 mm bore provides 3681 N. The SAID80X90 uses a G3/8 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB and CA options.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Note that a plain SAID does not hold a load when air is lost; for position holding, consider SAIL or BSAID. Since no -S magnet is specified, position sensing requires external flags rather than CMSE or DMSE switches.
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 SAID80X90 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers an equal force of 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both extend and retract directions.
No, the SAID80X90 is a standard double-acting cylinder and will drift if air pressure is lost or the valve is centered. The adjustable air cushions only decelerate the piston near stroke end. For position holding, consider SAIL or BSAID models.
