Airtac SAID80 Double Rod Cylinder SAID80AX65S
The AirTAC Airtac SAID80 Double Rod Cylinder SAID80AX65S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 65mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID80 Double Rod Cylinder SAID80AX65S
The AirTAC SAID80X65-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 65mm stroke and an integrated magnet for position sensing. Because the piston rod exits both end covers, the annular effective area is identical in both directions, yielding equal push and pull forces of 2268N at 0.5MPa (3175N at 0.7MPa). This through-rod geometry provides superior anti-rotation guidance and allows a secondary mechanism or position flag to be mounted on the rear rod.
This variant is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides, fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. Adjustable air cushions at both ends decelerate the piston near stroke end, though they do not hold the load if air pressure is lost.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX65S Is Used
Symmetric Force Transfer
Drives equal push and pull loads of 2268N at 0.5MPa in both directions, ideal for transfer systems requiring identical force profiles for extension and retraction.
Anti-Rotation Slides
The through-rod exiting both end covers keeps the load guided against rotation better than a single-rod cylinder, stabilizing heavy vertical slides.
Through-Rod Sensing
The rear rod end mounts a cam or position flag to trigger CMSE or DMSE sensors, keeping the primary work tool and sensing elements on separate rod ends.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX65S the Right Cylinder?
Select this 80mm bore when an application requires symmetric force and speed both ways, stepping up from the 63mm bore (1402N at 0.5MPa) or down from the 100mm bore (3681N at 0.5MPa). A double-rod design is chosen over a single-rod SAI when the mechanism needs dual-side actuation, strict anti-rotation control, or rear-rod limit sensing. For dimensionally interchangeable drop-in replacements, match the 80mm bore, 65mm stroke, G3/8 PT port, and the required mounting accessory from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Note that a plain SAID cylinder will drift if air is exhausted or the valve is centered; applications requiring true position holding without live pressure should use an external rod lock, a SAIL lock cylinder, or a BSAID clamp-lock cylinder. The 25mm rod diameter and M20x1.5 thread provide robust side-load capacity, but always ensure the rear rod has adequate clearance to protrude during operation.
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 SAID80AX65S FAQ
Because the rod occupies both sides of the piston, the effective area is the same on extend and retract. The force is equal both ways: 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, the SAID profile cylinder is dimensionally interchangeable per ISO 15552 mounting-interface dimensions. You can drop it in for other ISO 15552 double-rod cylinders by matching the 80mm bore, 65mm stroke, and G3/8 port.
