About the Airtac SAID80 Double Rod Cylinder SAID80X120S
The AirTAC SAID80X120-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 120mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding an equal 2268N of force in both directions at 0.5 MPa. The standard carbon steel rod provides robust durability for industrial actuation.
Equipped with a magnet (-S), this model supports AirTAC CMSE reed and DMSE electronic sensors mounted into the dual extruded grooves on the barrel. The rear rod extension is ideal for mounting a secondary cam, position flag, or driving a second mechanism, while offering superior anti-rotation guidance compared to a single-rod SAI.

Where the Airtac SAID80 Double Rod Cylinder SAID80X120S Is Used
Symmetric Force Transfer
Drives loads requiring identical push and pull kinetics, utilizing the equal annulus area to maintain 2268N of consistent force in both directions.
Anti-Rotation Slides
Keeps heavy workpieces guided and prevents torsional drift by using the twin rods exiting both ends as a rigid linear rail.
Through-Rod Sensing
Actuates a primary tool on the front stroke while the rear rod extension triggers DMSE electronic sensors for dual-station verification.
Is the Airtac SAID80 Double Rod Cylinder SAID80X120S the Right Cylinder?
Select this 80mm bore when an application requires symmetric push and pull forces up to 2268N at 0.5 MPa, or step down to the 63mm bore (1402N both ways) if your load is lighter. The double-rod design is chosen over a single-rod cylinder when you need dual-side guidance to prevent rotation, or require rear-end position sensing. Fluid must be filtered air (40 um) operating between 0.15-1.0 MPa.
This cylinder uses PT tapered port threads (G3/8) and is dimensionally interchangeable per ISO 15552. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). Note that a plain SAID does not hold position if air pressure is lost; for dead-load holding, consider SAIL or BSAID variants. Since the stroke is 120mm, side-load stress on the rod bearing is minimal, but external guides are recommended for any heavy offset loads.
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 SAID80X120S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID80X120-S is dimensionally interchangeable with other ISO 15552 profile cylinders. It shares the same mounting footprint and uses a G3/8 port, though you must ensure adequate rear clearance for the protruding secondary rod.
