About the Airtac SAI50 Standard Cylinder SAI50AX180S
The AirTAC SAI50X180-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 180mm stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a magnet for proximity sensing via CMSE or DMSE switches fitted into the dual sensor grooves. It is built with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance, and utilizes PT tapered port threads for secure pneumatic connections.

Is the Airtac SAI50 Standard Cylinder SAI50AX180S the Right Cylinder?
Choosing this 50mm bore over the smaller 40mm option upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to the 63mm bore yields 1559 N if your application requires moving heavier payloads. The 180mm stroke falls well within the 1200mm maximum standard stroke limit, making it a readily available choice for typical actuation distances.
Because this is a double-acting cylinder, it requires continuous air pressure to both extend and retract. If your machinery loses air supply, the piston will drift and cannot hold a load in place; for vertical or safety-critical load holding, consider the SAIL variant with an air-released lock or an external rod lock. When replacing an existing unit, ensure the 50mm bore, 180mm stroke, PT G1/4 port, and appropriate mounting accessories like an FA flange or TC trunnion match your footprint.
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 SAI50 Standard Cylinder SAI50AX180S FAQ
At a standard operating pressure of 0.5 MPa, this 50mm bore cylinder generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552. As long as the bore, stroke, port size (G1/4), and mounting accessories match, it serves as a direct replacement for other ISO 15552 profile cylinders.
