About the Airtac SAI40 Standard Air Cylinder SAI40BX1000S
The AirTAC SAI40X1000-S is a double-acting ISO 15552 profile cylinder engineered for long-stroke automation. It delivers 628 N of push force at 0.5 MPa, making it suitable for moving moderate loads over extended distances. This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for position sensing.
Because the stroke reaches the 1000 mm maximum standard limit for this bore, the extruded aluminum barrel incorporates adjustable air cushions at both ends to decelerate the piston smoothly. The dual sensor grooves on the barrel sides allow for easy mounting of CMSE or DMSE reed switches without requiring extra hardware.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX1000S Is Used
Long-Stroke Diverting
Pushes products across wide conveyor belts over a 1000 mm distance where moderate 628 N thrust is sufficient.
High-Bay Extraction
Extracts totes from deep storage racks, utilizing the SUS304 rod to resist humidity in warehouse environments.
Linear Transfer
Moves workpieces between machining stations, relying on dual adjustable cushions to stop the 1-meter travel smoothly.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX1000S the Right Cylinder?
Choose this 40 mm bore when an application requires a 1000 mm stroke but the 32 mm bore (offering 402 N at 0.5 MPa) lacks the necessary thrust. If your system needs to move heavier components across the same distance, stepping up to the 50 mm bore provides 982 N at 0.5 MPa.
At 1000 mm of extension, the piston rod is highly susceptible to bending under side loads. Use an external guide rail or a guided cylinder to prevent rod-bearing damage. Note that this standard cylinder will drift if air pressure is lost; for position holding, consider the SAIL variant with an air-released lock. This model features PT tapered G1/4 ports, uses an FA flange or LB foot mounting, and is a direct dimensional direct for any ISO 15552 cylinder footprint.
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 SAI40BX1000S FAQ
