About the Airtac SAI50 Standard Cylinder SAI50BX240S
The AirTAC SAI50X240-S is a double-acting profile cylinder built to the ISO 15552 standard, providing a direct mounting interface for universal automation compatibility. It delivers a thrust of 982 N at 0.5 MPa, making it well-suited for mid-range actuation tasks requiring a 240 mm stroke.
This specific configuration features a SUS304 stainless steel rod for enhanced corrosion resistance in humid or washdown environments. It includes a piston magnet for use with CMSE and DMSE sensor switches, which ride securely in the dual grooves machined into the extruded aluminum barrel.

Where the Airtac SAI50 Standard Cylinder SAI50BX240S Is Used
Packaging Lines
Handles product diverting and lane merging tasks where the 240 mm stroke provides the exact reach needed to clear passing packages.
Component Seating
Presses small bearings or pins into housings, utilizing the 982 N of push force at 0.5 MPa to ensure proper alignment without over-stressing parts.
Pallet Handling
Pushes or lifts light pallets and tier stands, relying on the SUS304 rod to resist moisture encountered in unloading docks.
Is the Airtac SAI50 Standard Cylinder SAI50BX240S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, whereas moving up to a 63 mm bore provides 1559 N for heavier payloads. At 240 mm of travel, the unsupported rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder will protect the rod bearing and prevent premature wear.
This cylinder uses a PT G1/4 port and operates effectively between 30-800 mm/s. It functions as a direct dimensional replacement for any ISO 15552 cylinder of the same bore and stroke. Note that the adjustable air cushions only decelerate the piston at end-of-stroke; if the machine loses air pressure, the load will drift, requiring an external check valve or the SAIL locking variant for fail-safe 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.
Airtac SAI50 Standard Cylinder SAI50BX240S FAQ
At an operating pressure of 0.5 MPa, the SAI50X240-S generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X240-S is dimensionally interchangeable with any standard ISO 15552 profile cylinder of the same 50 mm bore and 240 mm stroke. Just ensure your existing mounting hardware and G1/4 port connections align.
