About the Airtac SAI200 Standard Cylinder SAI200AX240S
The AirTAC SAI200X240-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The 240 mm stroke provides the extended travel needed for large presses and heavy material handling. Its extruded aluminum barrel design ensures a rigid yet lightweight structure without tie-rods.
This specific configuration includes a magnet (-S) for use with CMSE and DMSE sensor switches, which seat directly into the dual grooves on the barrel. It is built with an A-code SUS420J2 stainless steel rod for superior corrosion resistance compared to standard carbon steel. The PT tapered port threads guarantee a robust, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI200 Standard Cylinder SAI200AX240S Is Used
Heavy Metal Stamping
Provides the immense 15708 N push force required to actuate large-scale stamping presses and heavy-gauge metal forming equipment.
Automotive Assembly Jigs
Drives robust positioning fixtures and heavy lift-gates on automotive production lines, utilizing the -S magnet for end-of-stroke confirmation.
Bulk Material Diverters
Powers heavy-duty diverter arms on bulk material conveyors, where the SUS420J2 stainless rod resists harsh industrial environments.
Is the Airtac SAI200 Standard Cylinder SAI200AX240S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when 160 mm (10053 N at 0.5 MPa) lacks the necessary thrust for your heaviest machinery. The 240 mm stroke falls well within the 1500 mm standard limit, but because it exceeds 300 mm, you must account for side-load forces. An unsupported rod of this length can bend under lateral stress; integrate an external guide rail or use a guided cylinder to protect the rod bearing and seals.
For position holding, a standard SAI cylinder will drift and drop its load if air pressure is lost or exhausted. The adjustable air cushions at both ends only decelerate the piston near stroke end; they do not act as a mechanical brake. If your application requires fail-safe load holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, matching the 200 mm bore, 240 mm stroke, G3/4 port, and standard mounting accessory dimensions.
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 SAI200 Standard Cylinder SAI200AX240S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can reach up to 21991 N push at 0.7 MPa.
No, the standard SAI cylinder will drift or drop if air pressure is lost. The adjustable air cushions only decelerate the piston at stroke end and do not act as a lock. For fail-safe holding, use the SAIL or BSAI locking variants.
