About the Airtac SAID80 Double Rod Cylinder SAID80AX225S
The AirTAC SAID80X225-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 225mm stroke and an integrated magnet. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding exactly 2268N of force in both extend and retract directions at 0.5MPa. This symmetric output is ideal for mechanisms requiring equal push and pull dynamics.
Equipped with a SUS420J2 stainless steel rod (option A), this variant provides enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches directly. Note that 225mm is a non-standard stroke length, made to order, and the through-rod design requires additional rear clearance in your machine layout.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX225S Is Used
Symmetric Force Transfer
Drives shuttle mechanisms where the equal 2268N push and pull forces prevent stalling or asymmetric acceleration across the travel path.
Anti-Rotation Slides
The twin-rod design inherently resists torsional twisting, keeping heavy vertical slides aligned without needing external linear bearings.
Dual-Station Actuation
Mount a primary tool on the front rod and a secondary cam or limit flag on the rear protruding rod to trigger external sensors sequentially.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX225S the Right Cylinder?
Select this 80mm bore double-rod cylinder when your application demands equal bi-directional force and superior anti-rotation guidance. If you need less force, stepping down to the 63mm bore provides 1402N both ways at 0.5MPa; stepping up to the 100mm bore yields 3681N. The twin-rod architecture allows you to mount the primary workpiece on the front rod and a position flag or cam on the rear rod, which is impossible with a single-rod SAI.
This configuration uses PT tapered ports and includes the -S magnet for position sensing. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 225mm stroke exceeds the 80mm bore's standard maximum, it is a non-standard made-to-order item. Furthermore, strokes of 300mm or greater require external guidance to prevent rod-bearing bending, though this 225mm unit should still be checked for side-load if heavily cantilevered. Note that a plain SAID does not hold position when air is lost; use a BSAID clamp-lock or external pilot check valve for load holding.
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 SAID80AX225S FAQ
Because the double-rod design creates equal piston areas on both sides, it provides 2268N of force in both directions at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, it shares the exact ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 profile cylinders. It uses PT ports and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
