About the Airtac SAI160 Standard Cylinder SAI160AX280S
The AirTAC SAI160X280-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 14074 N at 0.7 MPa. Its 280 mm stroke is ideal for moving large masses in automated fabrication lines. This specific configuration includes a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and a PT tapered port thread ensuring a high-integrity pneumatic seal.
Equipped with a standard magnet (-S), the barrel features dual-sided sensor grooves that accept CMSE and DMSE reed switches for precise end-of-stroke detection. As a genuine extruded aluminum profile cylinder, it provides a direct, dimensionally interchangeable direct replacement for any ISO 15552 standard cylinder without relying on external tie-rods.

Where the Airtac SAI160 Standard Cylinder SAI160AX280S Is Used
Heavy Stamping Press
Provides the high thrust required for forming thick metal sheets and actuating large industrial press dies.
Pallet Diverting
Shifts heavy-loaded pallets across high-speed conveyor lanes in distribution hubs and warehouse logistics.
Automotive Assembly
Indexing and clamping heavy chassis components on automated automotive welding and framing lines.
Is the Airtac SAI160 Standard Cylinder SAI160AX280S the Right Cylinder?
Selecting this 160 mm bore is optimal when a 125 mm bore (providing 8590 N push at 0.7 MPa) is insufficient, but a 200 mm bore (21991 N) would be excessive overkill. The 280 mm stroke falls within the 1500 mm standard limit, but because it exceeds 300 mm, you must account for rod-bearing bending under side loads. Implement external guide rails or select a guided cylinder variant to prevent premature seal wear.
For applications requiring position holding without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke ends. You must integrate an external pilot-operated check valve or switch to the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants to prevent load drift or dropping.
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 SAI160 Standard Cylinder SAI160AX280S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can achieve a maximum theoretical push force of 18095 N at 0.9 MPa.
Yes. It is a true ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are fully interchangeable with other ISO 15552 compliant cylinders. Ensure your setup matches the G3/4 port and M36x2 rod thread.
