About the Airtac SAI200 Standard Cylinder SAI200AX240
The AirTAC SAI200X240 is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It generates a substantial 15708 N of push force at 0.5 MPa, extending 240 mm to move massive payloads. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops right into standardized ISO 15552 mounting interfaces.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches would require the -S variant instead.

Where the Airtac SAI200 Standard Cylinder SAI200AX240 Is Used
Stamping Press Feeders
Provides the 15708 N push force required to advance heavy metal coils or blanks into large mechanical presses.
Large Mold Handling
Extends 240 mm to position heavy injection molds or tooling fixtures securely onto machining centers.
Pallet Lift Stations
Lifts fully loaded industrial pallets using high thrust capacity while fitting standard ISO 15552 machinery profiles.
Is the Airtac SAI200 Standard Cylinder SAI200AX240 the Right Cylinder?
Selecting this 200 mm bore model makes sense when 160 mm (10053 N push at 0.5 MPa) is insufficient for your load. If 240 mm stroke leaves excess room, dropping to a 200 mm stroke keeps the same thrust while saving cycle time. Because this is a double-acting cylinder, it relies entirely on continuous air pressure to hold position; if your system loses air or the valve centers, the load will drift. For fail-safe holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.
To match this cylinder for an ISO 15552 replacement, verify the 200 mm bore, 240 mm stroke, G3/4 port, and your required mounting accessory (such as TC trunnion or LB foot). Since the stroke is under 300 mm, side-load stress on the rod bearing is moderate, but external guides are still 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 SAI200 Standard Cylinder SAI200AX240 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X240 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, provided your port (G3/4), stroke, and mounting match.
