About the Airtac SAID80 Double Rod Cylinder SAID80AX90S
The AirTAC SAID80X90-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a magnetic piston. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 2268 N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for applications requiring consistent speed and power regardless of travel direction.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, PT tapered port threads, and a built-in magnet for position sensing. The rear rod protrusion allows you to mount a secondary cam or position flag, while the extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX90S Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical 2268 N force and speed in both directions, ensuring smooth cycling without momentum shifts.
Anti-Rotation Slides
Twin rods guide the payload securely, preventing torsional twist on the piston face during heavy horizontal indexing.
Rear-End Position Flagging
Uses the protruding rear rod to trigger an external mechanical limit switch or mount a secondary cam for dual-station actuation.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX90S the Right Cylinder?
Select this 80mm bore when an application demands equal push and pull forces, specifically 2268 N each way at 0.5 MPa. If your mechanism requires less force, stepping down to the 63mm bore provides 1402 N both ways. Conversely, heavier loads may necessitate the 100mm bore, which outputs 3681 N symmetrically. The twin-rod design is chosen over a single-rod SAI when the load needs dual-side guidance to prevent rotation, or when a rear rod is required to drive a secondary mechanism.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state sensors. It is dimensionally interchangeable per ISO 15552, offering a drop-in replacement for other ISO 15552 double-rod cylinders. Note that a plain SAID does not hold its position if air pressure is lost; for dead-load holding, consider an external rod lock or the BSAID clamp-lock variant. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAID80AX90S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal force of 2268 N in both extend and retract directions at 0.5 MPa, and 3175 N at 0.7 MPa.
