About the Airtac SAI40 Standard Air Cylinder SAI40AX1000S
The AirTAC SAI40X1000-S is a double-acting ISO 15552 profile cylinder engineered for long-stroke linear motion. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it suitable for moving moderate loads over a substantial 1000 mm travel distance. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It is built with a -S magnet for direct mounting of CMSE or DMSE series sensor switches along the dual-side grooves. Fluid ports feature PT tapered threading, and the adjustable air cushions at both ends absorb end-of-stroke impact.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX1000S Is Used
Long-Stroke Material Handling
Drives large transfer gates or pusher arms across wide conveyor belts where a full 1000 mm extension is required to clear the production line.
Automated Storage Retrieval
Extends actuator arms in automated warehousing systems to reach deep into storage racks, utilizing the 628 N push force to shift moderate pallet loads.
Large Door Actuation
Opens and closes heavy industrial machine guarding doors or access panels, relying on adjustable end cushions to prevent slamming at full extension.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX1000S the Right Cylinder?
Because this 1000 mm stroke pushes the limits of the 40 mm bore class, side load is a primary concern. An unsupported rod of this length will bend under lateral stress, so you must use external guide rails or opt for a fully guided cylinder to prevent premature rod-bearing wear. If your application requires less travel, stepping down to a 50 mm bore with a shorter stroke provides 982 N push force at 0.5 MPa, offering a stiffer assembly. For position holding without constant air pressure, use the SAIL locking variant or an external rod lock, as the standard cushion only decelerates the piston and does not brake the load. To replace this unit, match the 40 mm bore, 1000 mm stroke, G1/4 PT port, and the -S magnet requirement.
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 SAI40AX1000S FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 40 mm bore, 1000 mm stroke, and G1/4 port size without modifying the machinery.
