About the Airtac SAID80 Double Rod Cylinder SAID80BX150S
The AirTAC SAID80X150-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 150mm stroke. Because the piston rod exits both end covers, the annulus area is identical on both sides, yielding exactly 2268N of force in both extend and retract directions at 0.5 MPa. The -S suffix indicates an integrated magnet for position sensing.
This specific configuration incorporates SUS304 stainless steel rods (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches precisely where needed without extra brackets.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX150S Is Used
Symmetric Force Transfer
Drives a workpiece from one end while the opposing rear rod simultaneously shifts a secondary mechanism, utilizing the exact 2268N matching thrust in both directions.
Anti-Rotation Slides
The twin SUS304 rods provide inherent torsional resistance, keeping guided loads perfectly stable without relying solely on external linear bearings.
Through-Rod Sensing
Uses the integrated -S magnet with DMSE electronic switches on the dual-side barrel grooves to track the rear rod position for precise end-of-stroke confirmation.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX150S the Right Cylinder?
Select this 80mm bore when an application demands symmetric thrust of 2268N each way at 0.5 MPa, stepping up from the 63mm bore (which provides 1402N) to handle heavier symmetric loads. A double-rod design is chosen over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear cam and position flag must drive a secondary mechanism. Note that a plain double-rod cylinder drifts if air pressure is lost; for dead-load holding, consider a SAIL lock or external pilot-operated check valve.
For ISO 15552 drop-in replacement, match the 80mm bore, 150mm stroke, PT port thread, and rear-rod clearance. Available mounting accessories include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 150mm stroke is under the 300mm threshold, so standard rod bearing bending is minimal, though external guides are always recommended for heavy off-center 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 SAID80BX150S FAQ
Because it is a double-rod cylinder, the effective piston area is equal on both sides. It provides 2268N of force in both the extend and retract directions at 0.5 MPa, and 3175N at 0.7 MPa.
Yes, the SAID80X150-S is dimensionally interchangeable per ISO 15552. You can drop it in for other ISO 15552 double-rod cylinders by matching the 80mm bore, 150mm stroke, and PT port, but ensure you have rear-rod clearance.
