About the Airtac SAID80 Double Rod Cylinder SAID80AX15S
The AirTAC SAID80X15-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 15mm stroke. A single piston drives a rod out of both end covers, yielding equal effective annulus areas on both sides. This means extend and retract forces are perfectly matched at 2268N each way at 0.5MPa, preventing speed asymmetry common to single-rod units.
This configuration includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. The integrated magnet (-S) enables position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed in the dual-side barrel grooves. PT tapered port threads are standard.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX15S Is Used
Symmetric Force Transfer
Drives heavy horizontal slides where equal push and pull forces (2268N at 0.5MPa) prevent motor stall or asymmetric acceleration during rapid reversals.
Anti-Rotation Guidance
Uses the dual through-rods to guide heavy vertical lifts without the rotational twist or sagging deflection seen in single-rod actuators.
Dual-Side Tool Actuation
Mounts the primary workpiece on the front rod and a secondary cam or position flag on the rear rod to trigger external sequence valves.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX15S the Right Cylinder?
Choose this 80mm bore when an application requires substantial symmetric force, as it generates 2268N in both directions at 0.5MPa. Stepping down to a 63mm bore drops the bidirectional force to 1402N, while upgrading to a 100mm bore raises it to 3681N. The twin-rod design is essential here for anti-rotation guidance or mounting a secondary actuation cam on the rear rod, tasks a standard single-rod SAI cannot safely handle.
Because this is a short 15mm stroke, side-load stress on the rod bearing is minimal, though external guides are still recommended for heavy lateral loads. Note that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not hold a load. If the machine loses air pressure, the cylinder will drift. For true position holding, select an SAIL lock cylinder or an external pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAID80AX15S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It outputs 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa for both extension and retraction.
Yes, it shares the exact ISO 15552 mounting interface dimensions and can serve as a drop-in replacement for other ISO 15552 double-rod profile cylinders. It uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits single-rod-only brackets like FB or CA.
