About the Airtac SAID80 Double Rod Cylinder SAID80AX325
The AirTAC SAID80X325 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 325mm stroke and an extruded aluminum barrel. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding equal force and speed both ways. It generates 2268N in each direction at 0.5 MPa, and 3175N at 0.7 MPa.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced durability against side loads, and PT tapered port threads. The rear rod extension allows you to mount a cam or position flag, while the twin-rod design provides superior anti-rotation guidance compared to a single-rod SAI.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX325 Is Used
Symmetric Force Transfer
Drives a workload identically in both directions, leveraging the equal 2268N push and pull forces at 0.5 MPa for balanced push-pull machinery.
Anti-Rotation Slides
The twin-rod through-design prevents piston rotation, ideal for moving vertical lifting slides or guided gripper jaws without external torsional deflection.
Dual-Side Tool Actuation
Mounts the primary workpiece on the front rod and a secondary mechanism or mechanical flag on the rear rod to operate independent stations simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX325 the Right Cylinder?
Choose this 80mm bore when a 63mm bore (1402N at 0.5 MPa) is insufficient, but a 100mm bore (3681N at 0.5 MPa) is oversized. The double-rod layout is selected over a single-rod SAI when dual-side actuation, symmetric force, or rear-rod position sensing is required. To track position, add the -S magnet option for CMSE reed or DMSE electronic sensors.
With a 325mm stroke, the unsupported rod length increases bending stress on the rod bearing under side loads; an external guide rail is recommended to prevent premature wear. Note that a plain SAID does not hold a load if air pressure is lost—the adjustable air cushions only decelerate the piston near stroke end. For position holding without live pressure, consider an SAIL or BSAID clamp-lock cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAID80AX325 FAQ
Because the double-rod design subtracts the rod area on both sides, the force is equal in both directions. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID80X325 is dimensionally interchangeable per ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 double-rod profile cylinders. It uses a G3/8 port and PT tapered threads.
