About the Airtac SAI200 Standard Cylinder SAI200AX125
The AirTAC SAI200X125 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion tasks. Delivering a substantial 15708 N of push force at just 0.5 MPa, this 200 mm bore actuator is built to move large masses reliably.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads, and because no magnet is specified, it operates without integrated sensor tracking.

Where the Airtac SAI200 Standard Cylinder SAI200AX125 Is Used
Heavy Stamping
Provides the robust linear thrust needed to actuate large metal forming presses and heavy-duty stamping machinery.
Automotive Assembly
Ideal for positioning heavy chassis components or driving large riveting guns on automotive production lines.
Pallet Handling
Moves loaded industrial pallets or lifts substantial bulk material containers in high-capacity logistics hubs.
Is the Airtac SAI200 Standard Cylinder SAI200AX125 the Right Cylinder?
Selecting this 200 mm bore provides massive thrust, stepping up significantly from the 160 mm bore which yields 10053 N at 0.5 MPa. For applications requiring less force, dropping down to the 160 mm frame saves space and air consumption.
Because this is a standard double-acting cylinder, it cannot hold a load in place if air pressure is lost or exhausted. If your machinery requires mid-stroke locking or fail-safe holding under pressure loss, utilize the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead. This model mounts via standard ISO 15552 accessories like TC trunnions or FA flanges.
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.
