About the Airtac SAID80 Double Rod Cylinder SAID80X140
The AirTAC SAID80X140 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 140mm stroke. A single piston drives a carbon steel rod out of both end covers, yielding perfectly symmetric dynamics. Because the annulus area is identical on both sides, it generates 2268N of force at 0.5 MPa in both extend and retract directions.
This through-rod design allows you to mount the primary workpiece on one end and attach a secondary cam, position flag, or external guide on the rear. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Without a magnet specified, it uses standard adjustable air cushions at both ends to decelerate the piston, but it will not hold a load if air pressure is lost.

Where the Airtac SAID80 Double Rod Cylinder SAID80X140 Is Used
Symmetric Force Transfer
Drives a transfer carriage with equal 2268N push and pull force at 0.5 MPa, ensuring consistent cycle times regardless of travel direction.
Anti-Rotation Slides
Utilizes the twin-rod guidance to prevent mechanical twist on heavy vertical lifts, keeping the payload perfectly aligned without external guides.
Through-Rod Sensing
Mounts the primary tool on the front rod and a position flag on the rear rod to trigger rear-mounted sensors for end-of-trunk verification.
Is the Airtac SAID80 Double Rod Cylinder SAID80X140 the Right Cylinder?
Select the 80mm bore when your application requires 2268N of symmetric force at 0.5 MPa, bridging the gap between the 63mm bore (1402N) and the 100mm bore (3681N). The 140mm stroke is well within the 1500mm maximum standard stroke for this bore size, making it a readily available choice. The PT tapered G3/8 port ensures high flow capacity for the 30-800 mm/s speed range.
Choose this double-rod configuration over a single-rod SAI when your mechanism demands anti-rotation guidance, dual-station actuation, or rear-side position sensing. Since the stroke is under 300mm, side-load stress on the rod bearing is moderate, though an external guide is still recommended for heavy radial loads. For drop-in replacements, it is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, and CR). If position holding without live pressure is required, consider the SAIL or BSAID clamp-lock series instead.

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 SAID80X140 FAQ
Because the double-rod design subtracts the rod area from both sides, the extend and retract forces are equal. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa in both directions.
Yes, the SAID80X140 is a profile cylinder that is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing the same mounting interface and G3/8 port.
