About the Airtac SAI50 Standard Cylinder SAI50AX80S
The AirTAC SAI50X80-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. With an 80 mm stroke, it is purpose-built for compact automation tasks requiring rapid, repeatable mid-stroke movements. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The integrated magnet (-S) allows seamless operation with CMSE and DMSE reed switches, which seat neatly into the sensor grooves machined on both sides of the barrel.

Where the Airtac SAI50 Standard Cylinder SAI50AX80S Is Used
Package Diverting
Provides the precise 80 mm stroke and 982 N force needed to push packages off a high-speed sorting conveyor belt reliably.
Component Clamping
Secures lightweight metal or plastic components during machining operations, utilizing its SUS420J2 rod for durability against minor splatter.
Pallet Stops
Acts as a pneumatic stop gate in pallet handling lines, extending quickly to halt flow and retracting to release workpieces on demand.
Is the Airtac SAI50 Standard Cylinder SAI50AX80S the Right Cylinder?
Select this 50 mm bore when an application demands more power than a 40 mm cylinder (which provides 628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit. The 80 mm stroke is optimal for short-transfer operations without the side-load risks associated with longer extensions. If your workflow demands position holding during a pressure loss, pair this cylinder with the SAIL locking variant or an external pilot-operated check valve.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders. To match this exact unit, specify a 50 mm bore, 80 mm stroke, PT tapered port threads, your desired mounting accessory (such as LB foot or TC trunnion), and the -S magnet option.
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 SAI50AX80S FAQ
At 0.5 MPa operating pressure, 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 SAI50X80-S is built to the ISO 15552 dimensional standard, making it a direct replacement for other ISO 15552 profile cylinders. Ensure you match the 50 mm bore, 80 mm stroke, and mounting interface.
