About the Airtac SAI40 Standard Air Cylinder SAI40AX900S
The AirTAC SAI40X900-S is a double-acting ISO 15552 profile cylinder engineered for a 900mm stroke, delivering 628N of push force at 0.5 MPa. Its extruded aluminum barrel omits tie rods for a clean exterior, while the standardized mounting interface ensures dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. The integrated -S magnet enables direct mounting of CMSE or DMSE sensor switches in the dual side grooves, streamming position detection across the extended travel distance.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX900S Is Used
Material Transfer Lines
Drives long-travel pushers on conveyor systems, utilizing the 900mm stroke to index products between processing stations efficiently.
Automated Storage Retrieval
Actuates extending arms in compact storage systems, where the 628N force and integrated -S magnet track shuttle positioning accurately.
Long-Reach Sorting
Pushes sorted items across wide diverter gaps, benefiting from the SUS420J2 rod material in environments with potential moisture.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX900S the Right Cylinder?
With a 900mm stroke, this 40mm bore cylinder provides 628N thrust at 0.5 MPa; if your assembly requires heavier lifting, stepping up to the 50mm bore yields 982N. Conversely, lighter duty tasks can utilize the 32mm bore at 402N. The extended 900mm rod is highly susceptible to bending under side loads, so utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model features PT tapered port threads and operates at speeds between 30-800mm/s. Note that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not lock the load. If unpowered drift or dropping is unacceptable, an external pilot-operated check valve or the SAIL locking variant is required.
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 SAI40 Standard Air Cylinder SAI40AX900S FAQ
At a 0.5 MPa operating pressure, the SAI40X900-S generates 628N of push force and 528N of pull force. At the maximum rated pressure of 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X900-S shares the standardized ISO 15552 mounting interface and dimensions, making it a direct replacement for other ISO 15552 profile cylinders of the same bore size.
