About the Airtac SAI50 Standard Cylinder SAI50AX130
The AirTAC SAI50X130 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 130 mm stroke provides the exact mid-range travel needed for compact clamping and lifting tasks.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and, because it lacks the -S magnet option, is optimized purely for mechanical actuation without sensor tracking.

Where the Airtac SAI50 Standard Cylinder SAI50AX130 Is Used
Corrosive Clamping
Ideal for clamping machined parts in humid or mildly corrosive environments thanks to the SUS420J2 stainless steel rod.
Package Diverting
Provides the 982 N force needed to push heavy cartons off a production line within a compact 130 mm travel distance.
Gate Actuation
Reliable mid-stroke movement for opening and closing small machine guard doors or material hoppers.
Is the Airtac SAI50 Standard Cylinder SAI50AX130 the Right Cylinder?
Select this 50 mm bore when a 32 mm bore (402 N at 0.5 MPa) is underpowered, but a 63 mm bore (1559 N at 0.5 MPa) would be physically oversized for your envelope. The 130 mm stroke is a non-standard increment that bridges the gap between 125 mm and 150 mm, offering precise motion control.
As an ISO 15552 profile cylinder, it serves as a direct replacement for any standard 50 mm bore with a G1/4 port and 130 mm stroke. You can pair it with FA or FB flange accessories for rigid mounting. Note that standard air cushions only decelerate the piston at end-of-stroke; they will not hold a load if air pressure drops. For vertical loads requiring fail-safe holding, consider the SAIL 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 SAI50AX130 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X130 is dimensionally interchangeable per ISO 15552. It shares the same 50 mm bore, 130 mm stroke, and G1/4 port interface, allowing it to serve as a direct replacement for other ISO 15552 profile cylinders.
