About the Airtac SAI40 Standard Air Cylinder SAI40AX230S
The AirTAC SAI40X230-S is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 230 mm stroke provides the extended travel needed for packaging and material handling tasks. As a tie-rod-less extruded aluminum profile barrel, it ensures dimensionally interchangeable mounting per ISO 15552.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance compared to standard carbon steel. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE or DMSE reed switches in the dual sensor grooves. Fluid ports feature PT tapered threads, and the piston incorporates adjustable air cushions at both ends to decelerate loads smoothly.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX230S Is Used
Package Diverting
Provides the 879 N push force and 230 mm reach needed to actuate diverter arms on high-speed packaging conveyors.
Clamping Fixtures
The SUS420J2 stainless rod resists shop-floor humidity while securely clamping machined components during secondary operations.
Pallet Stops
Uses adjustable air cushions to smoothly decelerate and stop heavy pallets moving along gravity roller conveyors.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX230S the Right Cylinder?
Select this 40 mm bore when an application requires more thrust than the 32 mm variant (563 N at 0.7 MPa) but lacks the physical space for a 50 mm cylinder. The 230 mm stroke offers substantial extension, meaning external guides or a guided cylinder carriage are recommended to prevent rod-bearing bending under side loads.
This model is a direct replacement for any ISO 15552 cylinder matching its 40 mm bore, 230 mm stroke, and G1/4 port size. It does not hold its position if air pressure is lost; for load-holding requirements under dead air, specify the SAIL pneumatic lock or BSAI clamp-lock variant. Mounting accessories include LB foot brackets, FA flanges, or TC trunnion joints.
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 SAI40AX230S FAQ
At an operating pressure of 0.7 MPa, this double-acting 40 mm bore cylinder generates 879 N of push force and 528 N of pull force.
No, the standard SAI cylinder drifts when air pressure is removed. The air cushions only decelerate the piston at stroke end. For dead-air load holding, use the SAIL or BSAI locking variants.
