About the Airtac SAI40 Standard Air Cylinder SAI40AX900
The AirTAC SAI40X900 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 900mm stroke. It generates 628N of push force at 0.5 MPa and 879N at 0.7 MPa, making it well-suited for extended reach material handling. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. Fluid ports are PT tapered thread type. Because this is a standard 900mm stroke, it utilizes the maximum standard stroke length for this bore size while maintaining a 30-800 mm/s speed range.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX900 Is Used
Extended Reach Transfer
Pushes products across a 900mm gap between conveyor belts using 879N of force at 0.7 MPa.
High Bay Pusher
Actuates a long-stroke routing arm to divert pallets into distant storage lanes.
Long Stroke Ejection
Ejects molded parts from deep machine cavities where a standard 800mm stroke is insufficient.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX900 the Right Cylinder?
Selecting the SAI40X900 is ideal when a 900mm extension is required without moving into non-standard made-to-order territory. If an application requires less push force, stepping down is not recommended as 32mm bore drops the 0.5 MPa thrust to 402N. If higher forces are needed, the 50mm bore yields 982N at 0.5 MPa.
Because the stroke is 900mm, the unsupported rod length is substantial. Side loads will bend the rod bearing and cause premature wear; always utilize an external guide rail or a guided cylinder to support the load. Note that the adjustable air cushions only decelerate the piston at end-of-stroke and do not hold the load if air pressure is lost. For position holding without live pressure, consider the SAIL lock variant or an external rod lock.
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.
