About the Airtac SAI40 Standard Air Cylinder SAI40X700S
The AirTAC SAI40X700-S is a double-acting ISO 15552 profile cylinder engineered for automated handling. It yields 628N of push force at 0.5 MPa, extending across a 700mm stroke to suit long-travel material transfer. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that speeds up machine cleaning.
This variant includes a standard carbon steel piston rod and a magnetic piston for position feedback. The dual sensor grooves on the barrel accept CMSE or DMSE reed switches seamlessly. For high-temperature environments up to 70 C, the standard TPU seals provide reliable service, though Viton (H) or NBR (N) elastomers are available for specialized chemical or thermal exposure.

Where the Airtac SAI40 Standard Air Cylinder SAI40X700S Is Used
Long-Travel Transfer
Pushes packaged goods between conveyor zones over a 700mm distance, utilizing the 879N force at 0.7 MPa to overcome carton friction.
Pallet Push-Off
Acts as a diverter arm in packaging lines, where the magnetic piston triggers DMSE sensors to confirm extension before the sequence advances.
Automated Door Cycle
Opens and closes heavy machine guarding doors, relying on the adjustable cushioning to prevent slamming at the end of the 700mm travel.
Is the Airtac SAI40 Standard Air Cylinder SAI40X700S the Right Cylinder?
Choose this 40mm bore when a 32mm model (delivering 402N at 0.5 MPa) lacks the necessary thrust for moving heavier pallets, but a 50mm bore (982N at 0.5 MPa) would be physically oversized. The 700mm stroke is a standard configuration, yet at this length the unsupported rod is highly susceptible to bending under lateral loads. To prevent premature rod-bearing wear, implement an external linear guide rail or utilize a guided cylinder design.
As a true ISO 15552 standardized unit, this cylinder serves as a drop-in replacement for any ISO 15552 profile body matching the 40mm bore, 700mm stroke, and G1/4 PT port dimensions. Mounting hardware like FA flanges or LB foot brackets align perfectly. Remember that the adjustable air cushions only decelerate the piston at stroke ends; they do not lock the rod. If the machinery loses air pressure, the load will drift unless an external pilot-operated check valve or a SAIL locking cylinder is installed.
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 SAI40X700S FAQ
This 40mm bore cylinder generates 628N of push force at 0.5 MPa and 879N at 0.7 MPa. The maximum theoretical force at 1.0 MPa is 128 kgf.
Yes. The SAI series is dimensionally interchangeable per ISO 15552. As long as the competing unit shares the 40mm bore, 700mm stroke, and G1/4 port spacing, this AirTAC cylinder will mount directly into the existing fixture.
