About the Airtac SAI100 Standard Air Cylinder SAI100AX290
The AirTAC SAI100X290 is a double-acting ISO 15552 profile cylinder offering a robust 5497 N push force at 0.7 MPa. With a 100 mm bore and 290 mm stroke, this extruded aluminum barrel unit is built for heavy-duty automation. It features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and features PT tapered port threads.
This model includes adjustable air cushioning at both ends to decelerate the piston effectively. The barrel integrates dual-sided sensor grooves ready for CMSE or DMSE switches, though a magnet (-S suffix) must be specified separately to enable position detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX290 Is Used
Heavy Press Operations
Delivers 5497 N of thrust at 0.7 MPa for assembling bearings, stamping light components, and pressing fittings securely into housings.
Pallet Diverting
The 290 mm stroke provides the reach needed to push heavy pallets off a main conveyor line onto a secondary packaging branch.
Large Gate Actuation
Holds enough power and travel to open and close substantial machine safety gates or heavy material flow diverter doors on processing lines.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX290 the Right Cylinder?
Providing 3927 N of push force at 0.5 MPa, the 100 mm bore is ideal when the smaller 80 mm bore (2513 N at 0.5 MPa) lacks power, but the massive 125 mm bore (6136 N at 0.5 MPa) would be physical overkill. The 290 mm stroke is a standard length, keeping lead times predictable.
Because this stroke is 290 mm, the unsupported rod is susceptible to bending under side loads. Utilizing an external guide rail or a fully guided cylinder will prevent rod-bearing damage. Note that a standard SAI100X290 will drift if air pressure is lost; for fail-safe load holding, select the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the cushion. This cylinder is dimensionally interchangeable per ISO 15552, using a G1/2 port, and supports FA/FB flange or TC trunnion mounts.
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 SAI100 Standard Air Cylinder SAI100AX290 FAQ
At an operating pressure of 0.5 MPa, the SAI100X290 generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X290 is a true ISO 15552 profile cylinder, making its mounting interface and dimensions fully interchangeable with other ISO 15552 standard cylinders. You can use existing FA flange or TC trunnion mounting accessories.
