About the Airtac SAI40 Standard Air Cylinder SAI40AX700S
The AirTAC SAI40X700-S is a double-acting ISO 15552 profile cylinder featuring a 40 mm bore and a 700 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks requiring extended reach.
This specific configuration includes an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance in humid environments. Equipped with a magnetic piston (-S), it supports CMSE and DMSE position sensing via the dual sensor grooves machined into the extruded aluminum barrel. It uses tapered PT ports sized at G1/4.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX700S Is Used
Material Transfer
Drives long-travel pushers on conveyor lines to transfer products between workstations over a 700 mm distance.
Pallet Handling
Extends and retracts to position empty pallets at the infeed of packaging machinery, utilizing the magnetic piston for end-of-stroke confirmation.
Component Sorting
Actuates diverter gates on sorting conveyors, relying on the SUS420J2 rod to withstand mildly corrosive industrial washdowns.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX700S the Right Cylinder?
If your application requires less reach, stepping down to a SAI40X50-S halves the stroke while maintaining the same 628 N force. For higher force demands without increasing the stroke length, the SAI50X700-S offers 982 N at 0.5 MPa. At 700 mm, the unsupported rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other standard ISO 15552 cylinders of the same bore and stroke. It features adjustable air cushions at both ends to decelerate the piston, but note that it will drift if air pressure is lost; use the SAIL variant if true pneumatic locking is required for fail-safe load holding.
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.
