About the Airtac SAI50 Standard Cylinder SAI50X140S
The AirTAC SAI50X140-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 140mm stroke. It delivers a robust 982N push force at 0.5 MPa, making it well-suited for mid-range actuation tasks requiring precise 140mm travel.
Equipped with a standard carbon steel piston rod and a magnet for position sensing, this model integrates seamlessly with CMSE and DMSE switches via the dual-side sensor grooves on its extruded aluminum barrel. It features adjustable air cushions at both ends and uses PT tapered port threads for secure pneumatic connections.

Where the Airtac SAI50 Standard Cylinder SAI50X140S Is Used
Package Diverting
Provides the 982N force and 140mm stroke needed to push packages smoothly across diverter gates on high-speed sorting lines.
Component Clamping
Secures medium-sized metal workpieces during machining operations, utilizing the adjustable cushioning to prevent impact damage.
Pallet Stopper
Acts as a reliable pneumatic stop mechanism for pallets accumulating at conveyor transfer points within automated warehouses.
Is the Airtac SAI50 Standard Cylinder SAI50X140S the Right Cylinder?
If your application requires less force, stepping down to the 40mm bore yields 628N at 0.5 MPa, while moving up to the 63mm bore provides 1559N for heavier loads. This 140mm stroke falls well under the 1200mm maximum standard stroke for this bore, ensuring optimal stability without requiring external guides.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders for direct replacements. To match this exact configuration, specify the 50mm bore, 140mm stroke, G1/4 port, and the -S magnet option. Note that the standard double-acting design relies on continuous air pressure to hold position; if power fails, the piston will drift. For dead-end holding requirements, consider the SAIL locking variant.
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 SAI50X140S FAQ
At a standard operating pressure of 0.5 MPa, this 50mm bore cylinder provides a push force of 982N and a pull force of 825N. At 0.7 MPa, the push force increases to 1374N.
Yes, the SAI50X140-S is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions and G1/4 port make it fully interchangeable with other ISO 15552 profile cylinders, provided you specify the 140mm stroke and -S magnet option.
