About the Airtac SAI100 Standard Air Cylinder SAI100AX275S
The AirTAC SAI100X275-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore actuator provides a 275 mm stroke to handle substantial loads. Its extruded aluminum barrel design omits tie-rods, creating a sleek, integrated assembly that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes an integrated magnet for position sensing and utilizes SUS420J2 stainless steel for the piston rod. The dual sensor grooves machined into the barrel accept CMSE or DMSE switches, enabling precise end-of-stroke detection. Fluid compatibility is limited to filtered air, operating efficiently between 0.15 and 1.0 MPa.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX275S Is Used
Heavy Stamping Press
Provides the high 3927 N push force required to actuate heavy-duty stamping and forming presses at 0.5 MPa operating pressure.
Pallet Diversion
Utilizes the 275 mm stroke to push heavy product pallets off a main conveyor line, using the integrated magnet for cycle confirmation.
Large Mold Clamping
Secures large injection molds or heavy industrial fixtures during processing, taking advantage of the rigid 100 mm profile barrel.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX275S the Right Cylinder?
Selecting this 100 mm bore makes sense when a 80 mm cylinder lacks thrust; stepping down from a 125 mm bore saves space and air volume. At 0.5 MPa, the neighboring 80 mm bore yields 2513 N push force, whereas this 100 mm unit provides 3927 N, making it the optimal choice for mid-weight handling. The 275 mm stroke requires careful mounting to prevent rod-bearing wear. For applications exceeding 300 mm, or when absorbing high lateral loads, pair this cylinder with external linear guides or select a guided cylinder to prevent rod deflection.
Because it is a standard double-acting actuator, the SAI100X275-S relies on continuous air pressure to maintain its position. If pneumatic supply drops, the load will drift. For vertical loads requiring fail-safe holding, consider the SAIL variant with an air-released lock or the BSAI clamp-lock version. This model uses PT G1/2 ports and is fully interchangeable with other ISO 15552 cylinders via standard FA, FB, or TC mounting accessories.

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 SAI100AX275S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If pressure is increased to 0.7 MPa, the push force reaches 5497 N.
Yes, the SAI100X275-S is dimensionally interchangeable per ISO 15552. It shares standard mounting dimensions and G1/2 ports with other ISO 15552 profile cylinders, allowing a direct drop-in replacement.
