About the Airtac SAID80 Double Rod Cylinder SAID80AX425
The AirTAC SAID80X425 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because the piston rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 2268N of force in each direction at 0.5MPa.
This unit features a SUS420J2 stainless steel rod (A option) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches on either end to track the through-rod position.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX425 Is Used
Symmetric Force Transfer
Drives equal push and pull loads of 2268N at 0.5MPa, ensuring balanced actuation for pressing and clamping without force variation between directions.
Anti-Rotation Slides
The dual-rod geometry prevents piston twist, providing stable linear guidance for precision sliding fixtures over the 425mm travel.
Through-Rod Sensing
Uses the rear protruding rod end to mount a cam or flag, triggering DMSE electronic sensors on the opposite side from the primary workload.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX425 the Right Cylinder?
Select this 80mm bore when an application demands 2268N of push and pull force simultaneously, or step down to the 63mm bore if 1402N suffices. The twin-rod design inherently resists rotation and supports mounting a secondary cam or position flag on the rear rod end, unlike a single-rod SAI.
With a 425mm stroke, the 25mm rod and M20x1.5 thread can experience bending under heavy lateral loads, so an external guide is recommended. Note that the adjustable air cushion only decelerates the piston; it does not hold the load if air pressure drops. For position holding, consider a BSAID clamp-lock or external pilot-operated check valve. This model uses PT tapered 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 SAID80AX425 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It outputs 2268N in both extend and retract directions at 0.5MPa, and 3175N both ways at 0.7MPa.
Yes, the SAID80X425 is dimensionally interchangeable per ISO 15552 mounting dimensions. It uses a standard 80mm profile footprint with PT G3/8 ports, making it a drop-in replacement for comparable ISO 15552 double-rod cylinders.
