About the Airtac SAI100 Standard Air Cylinder SAI100AX290S
The AirTAC SAI100X290-S is a double-acting ISO 15552 profile cylinder engineered to deliver 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa. Its 290 mm stroke is well-suited for high-force automation sequences requiring substantial extension length.
Built with a SUS420J2 stainless steel rod (code A), this unit resists corrosion better than standard carbon steel. The integrated magnet (-S) pairs directly with CMSE or DMSE switches via the dual sensor grooves on the extruded aluminum barrel, while PT tapered ports ensure a tight pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX290S Is Used
Heavy Stamping Press
Provides the 5497 N push force at 0.7 MPa needed to actuate heavy-duty stamping and forming dies over a 290 mm travel distance.
Automated Assembly Lift
Lifts substantial pallet loads or chassis components during automated assembly, utilizing the integrated magnet for precise mid-stroke position detection.
Large Pallet Pusher
Pushes heavy pallets or totes along accumulation conveyors, taking advantage of the 100 mm bore's 3927 N thrust at 0.5 MPa operating pressure.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX290S the Right Cylinder?
Select this 100 mm bore when a 63 mm bore (providing 1559 N at 0.5 MPa) cannot meet your load requirements, or step down to it if an 80 mm bore (2513 N at 0.5 MPa) is underutilized. Because the 290 mm stroke creates an extended lever arm, avoid side loading the piston rod; use an external guide rail or a guided cylinder to prevent rod-bearing bending.
This unit is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other ISO 15552 profile cylinders. It uses a G1/2 port, M20x1.5 rod thread, and adjustable air cushions at both ends. If your application requires holding a load vertically without constant air pressure, use the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the cushion.
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.
