About the Airtac SAI200 Standard Cylinder SAI200AX325S
The AirTAC SAI200X325-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion. Operating at 0.5 MPa, it generates a substantial push force of 15708 N, making it well-suited for moving large masses over its 325 mm travel distance. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into existing ISO 15552 mounting interfaces.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A), offering excellent corrosion resistance for harsh or washdown environments. Equipped with a magnetic piston (-S), the barrel features integrated sensor grooves on both sides, allowing seamless installation of CMSE or DMSE reed switches for precise end-of-stroke detection.

Where the Airtac SAI200 Standard Cylinder SAI200AX325S Is Used
Heavy Metal Forming
Provides the robust linear thrust needed to actuate large mechanical presses and heavy stamping machinery in industrial metalworking facilities.
Automotive Component Handling
Delivers reliable high-force movement for positioning large chassis subframes or engine blocks along automotive production lines.
Pallet Handling
Drives heavy-duty lift mechanisms and pusher assemblies in automated distribution centers managing fully loaded industrial pallets.
Is the Airtac SAI200 Standard Cylinder SAI200AX325S the Right Cylinder?
When specifying this 200 mm bore actuator, verify that your application requires its 15708 N output at 0.5 MPa; stepping down to a 160 mm bore drops the push force to 10053 N, which may be insufficient for heavy loads. Because the 325 mm stroke creates an extended lever arm, side loads can severely stress the rod bearing and cause premature wear. For off-axis loads, implement an external linear guide or select a guided cylinder to prevent rod deflection. If the machinery must maintain position during a complete loss of air pressure, pair this cylinder with an external pilot-operated check valve or utilize the BSAI clamp-lock variant, as the adjustable air cushions only decelerate the piston at stroke ends and do not hold 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 SAI200AX325S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder exerts a push force of 15708 N. At 0.7 MPa, the output increases to 21991 N.
Yes, the SAI200X325-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can drop it into existing foot, flange, or trunnion mounts using the standard G3/4 PT port and M36x2 rod thread.
