About the Airtac SAI40 Standard Air Cylinder SAI40BX1000
The AirTAC SAI40X1000 is a double-acting ISO 15552 profile cylinder engineered for long-reach linear motion. It generates 879 N of push force at 0.7 MPa and utilizes a 1000 mm stroke to span substantial operational gaps.
Built with a SUS304 stainless steel piston rod and PT tapered G1/4 ports, this extruded aluminum barrel unit resists corrosion while maintaining a standardized mounting interface. It lacks a standard magnet, so position sensing requires custom modifications or a different variant.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX1000 Is Used
Long-Stroke Material Transfer
Pushes products across wide conveyor gaps using the full 1000 mm extension, relying on external guides to maintain straight tracking.
High-Reach Pallet Pushing
Transitions heavy pallets laterally on packaging lines where 879 N of thrust at 0.7 MPa is sufficient to overcome sliding friction.
Automated Door Actuation
Opens and closes large industrial machine safety doors, utilizing the SUS304 rod to withstand occasional environmental moisture.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX1000 the Right Cylinder?
Selecting this 40 mm bore over the smaller 32 mm bore increases your 0.5 MPa push thrust from 402 N to 628 N, providing extra power for heavier loads. For a 1000 mm stroke, the extended unsupported rod is highly susceptible to bending under side loads; always utilize an external guide rail or a dedicated guided cylinder to prevent rod-bearing damage.
This model provides direct dimensional interchangeability with other ISO 15552 cylinders, requiring only matching PT G1/4 porting and standard FA or LB mounting accessories. If the machinery loses air pressure, the piston will drift and cannot hold a load vertically; integrate an external pilot-operated check valve or the SAIL locking variant for fail-safe positioning.
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 SAI40BX1000 FAQ
At an operating pressure of 0.7 MPa, this 40 mm bore cylinder provides a push force of 879 N and a pull force of 528 N.
Yes, it is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing mounts, but ensure your air lines match the PT G1/4 port thread.
