About the Airtac SAI40 Standard Air Cylinder SAI40BX700S
The AirTAC SAI40X700-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 700mm stroke. It delivers a push force of 879 N at 0.7 MPa, making it suitable for medium-duty linear motion tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that matches standard ISO 15552 mounting dimensions.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh environments. It is equipped with a magnet for proximity sensing via CMSE or DMSE switches, which mount directly into the dual sensor grooves on the barrel. Ports feature PT tapered threads, and adjustable air cushions at both ends ensure smooth deceleration across the long 700mm travel.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX700S Is Used
Material Transfer
Ideal for pushing packages or parts along a 700mm transfer distance on automated packaging lines.
Component Indexing
Moves workpieces between machining stations where a long stroke and 879 N force are required.
Welding Positioning
The SUS304 rod withstands sparks and debris, making it reliable for positioning welding fixtures.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX700S the Right Cylinder?
When selecting this actuator, verify that the 879 N output at 0.7 MPa is sufficient for your load. If your application requires less force, stepping down to a 32mm bore yields 563 N, while upgrading to a 50mm bore provides 1374 N. Because the 700mm stroke generates significant extension, side loads can bend the rod bearing; an external guide or a guided cylinder is strongly recommended to prevent premature wear.
This model provides a true ISO 15552 mounting interface, meaning it is dimensionally interchangeable with other ISO 15552 profile cylinders. To complete your setup, pair the 40mm bore with a PT port thread, an appropriate mounting accessory like an FA flange or TC trunnion, and ensure your sensing setup is compatible with the -S magnet option. If the machinery loses air pressure, this standard cylinder will not hold the load in place; for position holding without live pressure, 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 SAI40BX700S FAQ
At an operating pressure of 0.7 MPa, the 40mm bore provides a push force of 879 N. At 0.5 MPa, the push force is 628 N.
Yes, the SAI40X700-S is built to the ISO 15552 profile standard, making its mounting dimensions fully interchangeable with other ISO 15552 cylinders, though it is an AirTAC branded component.
