About the Airtac SAID80 Double Rod Cylinder SAID80AX35
The AirTAC SAID80X35 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 35 mm stroke and an extruded aluminum barrel. Because a piston rod exits both end covers, the annulus area is identical on both sides, yielding an equal extend and retract force of 2268 N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent push and pull dynamics.
This specific configuration incorporates a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, while adjustable air cushions at both ends decelerate the piston near stroke limits.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX35 Is Used
Symmetric Force Transfer
Ideal for transfer systems requiring identical push and pull forces, utilizing the equal 2268 N annulus area in both directions to smoothly shuttle loads without speed variations.
Anti-Rotation Slides
The twin-rod design provides superior resistance to torsional deflection, keeping guided slides perfectly aligned and preventing workpiece binding during vertical strokes.
Rear-Rod Position Flag
The protruding rear rod can independently drive a secondary mechanism or mount a limit flag, allowing external position verification without interfering with the primary workpiece area.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX35 the Right Cylinder?
Choose this 80 mm bore double-rod actuator when an application demands anti-rotation guidance, twin-station actuation, or a rear-rod position flag that a single-rod SAI cannot provide. If your project requires less force, stepping down to the 63 mm bore yields 1402 N both ways at 0.5 MPa; for heavier loads, the 100 mm bore provides 3681 N.
Ensure you specify the correct mounting accessories from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR are exclusive to single-rod variants. Remember that a plain SAID does not hold its position if air pressure is lost; for fail-safe load holding, consider an external rod lock or the BSAID clamp-lock series. This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders.

- ✓ 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 SAID80AX35 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the push and pull forces are equal. It generates 2268 N both ways at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X35 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, matching standard mounting and port dimensions.
