About the Airtac SAI50 Standard Cylinder SAI50X240S
The AirTAC SAI50X240-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. With a 240 mm stroke, this unit is designed for operations requiring substantial mid-range travel. The extruded aluminum barrel eliminates tie-rods, providing a clean profile that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a magnet for proximity sensing and uses a standard carbon steel piston rod. The barrel features integrated sensor grooves on both sides, allowing seamless mounting of CMSE or DMSE switches. For environments running at elevated temperatures, the seals can be swapped from standard TPU to Viton (H) to ensure continuous reliable operation.

Where the Airtac SAI50 Standard Cylinder SAI50X240S Is Used
Package Diversion
Provides the 982 N push force and 240 mm travel needed to actuate routing gates on high-speed packaging conveyors.
Clamp Actuation
Extends fully to secure medium-sized workpieces in CNC machining fixtures, utilizing the integrated magnet for end-of-stroke confirmation.
Pallet Stopping
Functions as a robust pneumatic stop on roller conveyors, handling pallets reliably within automated warehousing systems.
Is the Airtac SAI50 Standard Cylinder SAI50X240S the Right Cylinder?
Choose this 50 mm bore when an application requires stepping up from a 40 mm bore (628 N at 0.5 MPa) but does not need the full 1559 N output of a 63 mm cylinder. Because the 240 mm stroke creates an extended unsupported rod length, it is critical to manage side loads. Avoid rod-bearing bending by incorporating an external guide rail or selecting a fully guided cylinder for heavy off-center loads.
As a true ISO 15552 standard cylinder, this model serves as a direct replacement for any matching 50 mm bore, 240 mm stroke, PT port, and flange or foot mounting setup. Note that the adjustable air cushions only decelerate the piston at stroke ends; they will not hold a load if air pressure drops. For position holding without live pressure, use the SAIL or BSAI locking variants.
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 SAI50X240S FAQ
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X240-S is built to the ISO 15552 profile standard, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, provided you match the PT port and mounting accessories.
