About the Airtac SAID80 Double Rod Cylinder SAID80AX55
The AirTAC SAID80X55 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 55mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal bidirectional force of 2268N at 0.5MPa and 3175N at 0.7MPa. It uses a PT tapered port thread and operates at speeds of 30-800 mm/s.
This variant is equipped with SUS420J2 stainless steel rods (material code A) for enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear rod protrudes during operation, requiring additional clearance behind the cylinder compared to a single-rod SAI.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX55 Is Used
Symmetric Force Transfer
Drives a workpiece from one rod end while using the opposite end for a synchronized secondary motion, ensuring equal speed and force in both directions.
Anti-Rotation Slides
Utilizes the dual through-rods to guide heavy vertical loads against twisting, providing rigid linear motion without external guides.
Rear-Side Position Flag
Mounts a physical cam or sensor target on the rear rod end to trigger external limit switches without interfering with the primary front-side work area.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX55 the Right Cylinder?
Select this 80mm bore when an application requires symmetric push and pull forces alongside dual-side actuation. If you need less force, the 63mm bore offers 1402N each way at 0.5MPa; if you need more, the 100mm bore provides 3681N both directions. The twin-rod design is chosen over a single-rod SAI when a mechanism needs anti-rotation guidance, a rear-side position flag, or to drive a secondary cam.
This cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR mounts. It is double-acting only and does not hold a load if air pressure is lost; for position holding without live pressure, consider an external rod lock or the SAIL/BSAID series. The 55mm stroke keeps the unsupported rod length short, minimizing bending moments.
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 SAID80AX55 FAQ
Because it is a double-rod cylinder, the extend and retract forces are equal. It outputs 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa in both directions.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. It supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits the FB, CA, CB, and CR brackets found on single-rod versions.
