About the Airtac SAID80 Double Rod Cylinder SAID80AX425S
The AirTAC SAID80X425-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for applications requiring symmetric force and dual-side guidance. Because the piston rod exits both end covers, the effective annulus area is identical in both directions, yielding an equal extend and retract force of 2268N at 0.5MPa. This through-rod architecture inherently resists rotation and allows a secondary mechanism or position flag to be driven from the rear.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. It uses PT tapered ports and offers adjustable air cushioning at both ends to decelerate the load smoothly. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic switches.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX425S Is Used
Symmetric Force Transfer
Drives loads requiring identical push and pull dynamics, utilizing the 2268N both-way force to ensure consistent motion control without speed discrepancies between stroke directions.
Anti-Rotation Slides
The twin-rod design prevents piston rotation during travel, providing precise linear guidance for handling modules where a single rod would twist under offset loads.
Dual-Side Actuation
Mounts the primary workpiece on the front rod end while using the protruding rear rod to operate a secondary mechanism or mount a physical position flag for external tracking.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX425S the Right Cylinder?
Selecting this 80mm bore double-rod cylinder is ideal when your mechanism demands equal push and pull forces—such as 2268N at 0.5MPa—along with superior anti-rotation stability compared to a single-rod SAI. If your application requires less force, the 63mm bore offers 1402N both ways; if more force is needed, the 100mm bore provides 3681N. Note that a plain double-rod cylinder does not hold position if air pressure is lost; for dead-load holding, consider a BSAID clamp-lock variant or an external pilot-operated check valve.
With a 425mm stroke, the unsupported rod length increases the risk of side-load bending; utilizing an external guide rail is highly recommended to protect the rod bearing. This model is dimensionally interchangeable per ISO 15552 and supports a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Ensure you specify PT ports, the -S magnet, and the SUS420J2 rod option when replacing an ISO 15552 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 SAID80AX425S FAQ
Because it is a double-rod cylinder, the force is equal in both directions due to the matching annulus areas. It delivers 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa for both extend and retract strokes.
Yes, the SAID80X425-S is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses the standard ISO mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) and features a 25mm rod with an M20x1.5 thread.
