About the Airtac SAID80 Double Rod Cylinder SAID80AX35S
The AirTAC SAID80X35-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 25mm rod exiting both end covers. Because the piston area is equally subtracted by the twin rods on both sides, it generates an identical 2268N of thrust and pull force at 0.5 MPa in either direction. This symmetric output is ideal for applications requiring perfectly balanced advance and retract dynamics.
Equipped with a -S magnet, the extruded aluminum barrel integrates sensor grooves on both sides for flush mounting of CMSE reed or DMSE electronic switches. The rod is constructed from SUS420J2 stainless steel (option A) for heightened corrosion resistance, and the unit features adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX35S Is Used
Symmetric Force Transfer
Provides identical 2268N push and pull forces at 0.5 MPa for machinery requiring perfectly balanced dual-direction actuation without speed discrepancies.
Anti-Rotation Slides
The twin-rod design inherently resists torsional deflection, keeping guided workpieces perfectly aligned without needing external linear bearings.
Through-Rod Sensing
The rear rod extension protrudes from the back cover, allowing engineers to mount a secondary position flag or cam to trigger external DMSE sensors.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX35S the Right Cylinder?
Select this 80mm bore cylinder when an application demands 2268N of equal bidirectional force at 0.5 MPa, stepping up from a 63mm bore that yields 1402N. The twin-rod architecture is chosen over a single-rod SAI when the mechanism requires superior anti-rotation guidance or needs to drive a secondary cam and position flag from the rear rod extension. For dimensionally interchangeable drop-in replacements, this model conforms strictly to ISO 15552 mounting interface standards.
When specifying this cylinder, note the PT tapered port threads and the SUS420J2 stainless steel rod material. The available mounting accessories include Basic, FA, LB, TC, FTC, TCM1, and TCM2 variants. Because this is a standard double-acting cylinder, it does not hold a load if air pressure is lost; a SAIL or BSAID variant is required for pneumatic locking functions.
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 SAID80AX35S FAQ
Because the double-rod design occupies piston area on both sides, the effective annulus area is identical in both directions. It delivers 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa for both extension and retraction.
Yes, the SAID80X35-S is dimensionally interchangeable per ISO 15552 profile cylinder standards, allowing it to serve as a drop-in replacement for other ISO 15552 double-rod cylinders using the same mounting interface.
