About the Airtac SAID80 Double Rod Cylinder SAID80AX700
The AirTAC SAID80X700 is a double-acting, double-rod ISO 15552 profile cylinder with a 80 mm bore and 700 mm stroke. Because a piston rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed both ways. This model generates 2268 N at 0.5 MPa and 3175 N at 0.7 MPa in either direction. It features a PT tapered port thread and an adjustable air cushion at both ends.
Equipped with a SUS420J2 stainless steel rod (option A), this cylinder offers enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for mounting position switches. Note that a plain SAID does not hold its load when air pressure is lost; for locking requirements, consider the BSAID clamp-lock series.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX700 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 2268 N push and pull forces must be perfectly balanced to avoid jerky motion during direction reversal.
Anti-Rotation Slides
The twin rods exiting both ends keep the load guided against rotation better than a single rod, ideal for lifting vertical slides.
Through-Rod Sensing
The rear rod end protrudes 700 mm to actuate an external limit flag or cam, keeping the primary work tool isolated on the front rod.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX700 the Right Cylinder?
Select this 80 mm bore when an application requires symmetric force of 2268 N both ways at 0.5 MPa, stepping up from the 63 mm bore which provides 1402 N. The double-rod design is chosen over a single-rod SAI when the mechanism needs dual-side guidance, anti-rotation stability, or a rear rod end to mount a secondary cam or position flag. As an ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard double-rod cylinders using the same mounting interface.
At 700 mm stroke, the unsupported rod length is substantial. Even with the 25 mm rod diameter and M20x1.5 thread, long strokes increase the risk of rod-bearing bending under heavy lateral loads. An external guide should be used to prevent side-load damage. This configuration uses PT ports and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAID80AX700 FAQ
The SAID80X700 provides equal force in both extend and retract directions due to its double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X700 is a dimensionally interchangeable ISO 15552 profile cylinder. It uses a standard mounting interface but omits FB, CA, CB, and CR mounts, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2.
