About the Airtac SAI50 Standard Cylinder SAI50AX350
The AirTAC SAI50X350 is a double-acting ISO 15552 profile cylinder offering 982 N of push force at 0.5 MPa. Its 350 mm stroke is well-suited for medium-travel material handling and packaging tasks. The extruded aluminum barrel omits tie-rods, providing a clean exterior that simplifies cleaning and reduces debris buildup.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads. Because no magnet is specified, it is configured for standard pneumatic operation without internal sensing.

Where the Airtac SAI50 Standard Cylinder SAI50AX350 Is Used
Package Sorting Diverter
Provides the 982 N push force and 350 mm travel needed to cleanly divert heavy cardboard cartons between high-speed conveyor lanes.
Automated Pallet Handling
Ideal for pushing or positioning wooden pallets at machining centers, where the SUS420J2 rod withstands occasional environmental moisture.
Component Ejection Station
Delivers reliable 350 mm ejection strokes to clear stamped metal parts from press beds without interfering with tooling.
Is the Airtac SAI50 Standard Cylinder SAI50AX350 the Right Cylinder?
If your application requires less push force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, whereas moving up to a 63 mm bore provides 1559 N for heavier loads. At a 350 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, guide the load externally or specify a guided cylinder.
This model provides a direct replacement for any ISO 15552 cylinder with a 50 mm bore, 350 mm stroke, and G1/4 port. It supports mounting accessories like FA flanges or TC trunnions. Remember that the standard adjustable air cushions only decelerate the piston at end-of-stroke; they do not lock the rod. If you need true position holding without air pressure, select the SAIL lock 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 SAI50AX350 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 you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X350 is dimensionally interchangeable per ISO 15552 standards. You can directly replace any equivalent 50x350 ISO 15552 profile cylinder with a G1/4 port and matching mounting dimensions.
