About the Airtac SAI100 Standard Air Cylinder SAI100BX100S
The AirTAC SAI100X100-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 100mm stroke. It delivers a robust push force of 3927 N at 0.5 MPa, making it highly suitable for heavy-duty positioning tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It is equipped with a PT tapered port thread and an internal magnet (-S), allowing seamless integration with CMSE or DMSE reed sensors via the dual side grooves on the barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX100S Is Used
Automotive Body Welding
Provides the high clamping thrust (3927 N at 0.5 MPa) required to hold heavy steel body panels firmly in place during robotic welding operations.
Pallet Diverting
Pushes fully loaded heavy pallets onto branching conveyor lanes, utilizing the 100mm stroke and robust SUS304 rod to withstand repetitive impact forces.
Heavy Press Ejection
Exerts reliable downward force to eject dense manufactured components from hydraulic press dies, ensuring consistent cycle times without manual intervention.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX100S the Right Cylinder?
Selecting this 100mm bore model is appropriate when your application requires substantial thrust, such as 3927 N at 0.5 MPa or 5497 N at 0.7 MPa. If your load requirements are lower, stepping down to an 80mm bore yields 2513 N at 0.5 MPa, which may optimize air consumption. Conversely, applications needing extreme force should consider the 125mm bore providing 6136 N at 0.5 MPa.
Because the stroke is 100mm, side-load stress on the rod bearing is minimal, meaning standard mounting accessories like FA flanges or LB foot brackets are sufficient. Note that the standard variable air cushions only decelerate the piston at end caps; they do not lock the load. If your system loses air pressure, the rod will drift. For fail-safe load holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI clamp-lock version.
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 SAI100 Standard Air Cylinder SAI100BX100S FAQ
