About the Airtac SAI200 Standard Cylinder SAI200AX270S
The AirTAC SAI200X270-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 270 mm stroke is ideal for moving massive loads through extended travel distances in large-scale industrial machinery. Equipped with a standard PT tapered port thread, it ensures leak-free pneumatic connections under high flow demands.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A), providing excellent resistance to moisture and corrosion in humid environments. The integrated -S magnet allows seamless interaction with CMSE and DMSE series reed switches, fitting directly into the dual sensor grooves machined into the extruded aluminum barrel. As a genuine ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other standard cylinders of the same bore size.

Where the Airtac SAI200 Standard Cylinder SAI200AX270S Is Used
Heavy Metal Forming
Provides the massive 15708 N push force required to actuate large mechanical presses and stamping dies in heavy metal fabrication.
Large Injection Molding
Handles core pulling and heavy mold ejection tasks on large-scale injection molding machines requiring high force and 270 mm of travel.
Bulk Material Handling
Drives heavy-duty automated bulk material gates and diverter arms in mining or aggregate processing facilities.
Is the Airtac SAI200 Standard Cylinder SAI200AX270S the Right Cylinder?
Selecting the 200 mm bore is necessary when your application demands extreme thrust that smaller bores cannot provide, such as the 160 mm bore which offers 10053 N at 0.5 MPa. For this 270 mm stroke, side-load stress on the rod bearing is moderate but manageable; using external guide rails or a guided cylinder carriage is recommended if the load is heavy or off-center. To hold a load securely without continuous live air pressure, pair this cylinder with the BSAI bidirectional clamp-lock variant or an external rod lock, as the standard air cushions only decelerate the piston at stroke end and do not prevent drift. Replacement mounting interfaces include TC, FTC, and CA clevis accessories.
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 SAI200AX270S FAQ
At 0.5 MPa operating pressure, the SAI200X270-S cylinder delivers a push force of 15708 N and a pull force of 15080 N. It can reach a theoretical maximum push force of 21991 N at 0.7 MPa.
Yes, the SAI200X270-S is built to the exact ISO 15552 profile cylinder standard, making it dimensionally interchangeable with other ISO 15552 cylinders of the same 200 mm bore and 270 mm stroke, including standard PT port and TC mounting dimensions.
