About the Airtac SAI100 Standard Air Cylinder SAI100AX350
The AirTAC SAI100X350 is a double-acting ISO 15552 profile cylinder offering 5497 N of push force at 0.7 MPa. Its 350 mm stroke is well suited for moving heavy pallets or actuating large indexing mechanisms. The extruded aluminum barrel omits traditional tie-rods, presenting a clean exterior that resists debris accumulation.
This specific unit is configured with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid manufacturing environments. Fluid supply connects via PT tapered threads, and the barrel lacks an internal magnet, meaning it is ready for mechanical duty but not for direct magnetic position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX350 Is Used
Heavy Stamping
Provides the robust 5497 N output force required to actuate large presses and securely form thick metal components.
Pallet Transfer
Leverages the 350 mm stroke to push heavy loaded pallets smoothly between adjacent roller conveyor sections.
Automated Welding
Shifts heavy welding fixtures into precise alignment, utilizing the SUS420J2 rod to withstand harsh industrial environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX350 the Right Cylinder?
If 5497 N is insufficient for your payload, step up to the 125 mm bore which provides 8590 N at 0.7 MPa; conversely, the 80 mm bore yields 3518 N if you need to reduce physical size and air consumption. Because the 350 mm stroke creates an extended lever arm, unsupported side loads will severely stress the rod bearing and invite premature seal leakage. Employ an external linear guide or a guided cylinder carriage to absorb lateral forces.
The adjustable air cushions at both stroke ends decelerate the piston to protect machinery, but they do not lock the rod in place. If your machinery must hold a vertical load during a complete air pressure loss, integrate an external pilot-operated check valve or specify the SAIL pneumatic 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.
