About the Airtac SAI50 Standard Cylinder SAI50AX240S
The AirTAC SAI50X240-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 240 mm stroke provides the extended travel needed for mid-range material handling and automated clamping tasks. The extruded aluminum barrel design eliminates tie-rods, resulting in a cleaner profile that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a magnetic piston (-S) for seamless integration with CMSE and DMSE position sensors along the dual barrel grooves. It is built with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. PT tapered port threads ensure a robust, leak-free pneumatic connection on the G1/4 supply ports.

Where the Airtac SAI50 Standard Cylinder SAI50AX240S Is Used
Package Diverting
Provides the 982 N push force and 240 mm travel needed to actuate diverter arms on high-speed packaging lines.
Mid-Force Clamping
Secures metal or composite workpieces during CNC machining using the durable SUS420J2 stainless steel rod.
Pallet Stopping
Functions as a reliable pneumatic stop gate for pallets up to 50 kg, with adjustable cushions absorbing impact.
Is the Airtac SAI50 Standard Cylinder SAI50AX240S the Right Cylinder?
Select this 50 mm bore when an application requires more thrust than the 40 mm version (628 N at 0.5 MPa) but lacks the physical space for a 63 mm cylinder (1559 N at 0.5 MPa). Because the 240 mm stroke creates an extended rod length, designers must account for potential rod-bearing bending under heavy side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature seal wear.
For direct replacements, match the 50 mm bore, 240 mm stroke, G1/4 port, and PT thread type. Standard mounting accessories include FA/FB flanges, LB foot brackets, or TC trunnion joints. Remember that the adjustable air cushions only decelerate the piston at stroke ends; if the machine loses air pressure, the rod will drift. Use the SAIL variant or an external pilot-operated check valve 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.
Airtac SAI50 Standard Cylinder SAI50AX240S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder 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 -S suffix indicates a magnetic piston. You can mount CMSE or DMSE series switches directly into the sensor grooves on both sides of the aluminum profile barrel.
