About the Airtac SAI40 Standard Air Cylinder SAI40X1000
The AirTAC SAI40X1000 is a double-acting profile cylinder built to ISO 15552 dimensional standards, ensuring drop-in compatibility with globally standardized mounting interfaces. Delivering 879N of push force at 0.7 MPa, this 40mm bore unit is configured for an extended 1000mm stroke.
This configuration features a standard carbon steel piston rod and PT tapered port threads. While the base model lacks a magnet, the extruded aluminum barrel includes sensor grooves on both sides for adding CMSE or DMSE switches if position detection is added later.

Where the Airtac SAI40 Standard Air Cylinder SAI40X1000 Is Used
Long-Reach Diversion
Ideal for actuating diverter arms on wide conveyor systems where a 1000mm extension is required to push products cleanly across multi-lane belts.
Pallet Push-Off
Provides the 879N force at 0.7 MPa needed to push empty pallets or totes from an accumulation zone over extended distances.
Material Extrusion
Suitable for driving long-stroke material extrusion or blanking stations where a full 1-meter travel cycle is necessary to clear the work area.
Is the Airtac SAI40 Standard Air Cylinder SAI40X1000 the Right Cylinder?
Selecting this 40mm bore provides 628N of thrust at 0.5 MPa, offering a middle ground between the lighter 32mm bore (402N) and the heavier 50mm bore (982N). Because this model utilizes a 1000mm stroke, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature rod bearing wear.
When matching this part for an ISO 15552 replacement, verify the 1000mm stroke, G1/4 port, and required mounting accessories like LB foot brackets or FA flanges. Be aware that standard double-acting cylinders drift when air pressure is removed; if the application requires static load holding upon air loss, consider the SAIL locking variant or an external pilot-operated check valve.
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 SAI40X1000 FAQ
At an operating pressure of 0.7 MPa, the SAI40X1000 generates 879N of push force and 724N of pull force.
Yes, the SAI40X1000 is dimensionally interchangeable per ISO 15552. Verify your mounting dimensions, G1/4 port size, and 1000mm stroke requirements to ensure a proper drop-in fit.
