About the Airtac SAI40 Standard Air Cylinder SAI40BX100S
The AirTAC SAI40X100-S is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 100 mm stroke provides the exact extension needed for mid-range clamping and positioning tasks. Built with a tie-rod-less extruded aluminum barrel, it offers a clean profile while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or mildly chemical environments. It also features an integrated magnet (-S) that interfaces directly with CMSE or DMSE reed switches via the dual sensor grooves on the barrel. For higher temperature environments, the standard TPU seals can be swapped for Viton (H) or NBR (N) options.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX100S Is Used
Stainless Clamping
Ideal for securing machined components in wet machining centers where the SUS304 rod prevents rust and extends service life.
Package Diversion
Provides the 628 N pull force at 0.5 MPa needed to actuate routing gates and pusher arms on high-speed packaging lines.
Sensor-Driven Ejection
Uses the integrated magnet with DMSE switches to confirm retraction before ejecting molded parts from an automated assembly cell.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX100S the Right Cylinder?
Select this 40 mm bore when an application requires more power than a 32 mm bore (which provides 563 N at 0.7 MPa) but lacks the physical space for a 50 mm option. The G1/4 PT tapered port ensures efficient airflow for its 30-800 mm/s speed range. Because this is a double-acting cylinder, it relies entirely on continuous air pressure to move and hold the rod; it will drift if pressure is lost.
If your workflow demands positive load holding during an emergency stop or air loss, pair this cylinder with an external pilot-operated check valve or transition to the SAIL variant. To guarantee a seamless ISO 15552 replacement, verify the 40 mm bore, 100 mm stroke, G1/4 port, and mounting accessory type (such as LB foot or FA flange). Ensure you specify the -S magnet code when ordering if position feedback is required.
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 SAI40BX100S FAQ
At a standard operating pressure of 0.7 MPa, this 40 mm bore cylinder generates 879 N of push force and 738 N of pull force. At 0.5 MPa, it provides 628 N push and 528 N pull.
Yes, the SAI40X100-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other standard profile cylinders with a 40 mm bore, 100 mm stroke, and G1/4 port, provided you match the mounting accessories.
