About the Airtac SAI100 Standard Air Cylinder SAI100BX140
The AirTAC SAI100X140 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 3927 N at 0.5 MPa, extending 140 mm to drive high-inertia loads. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that resists debris accumulation.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in washdown or chemically active settings. It utilizes PT tapered port threads and lacks a standard magnet; for position detection, sensors require the -S variant to be specified at order entry.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX140 Is Used
Heavy-Duty Stamping
Generates 5497 N of push force at 0.7 MPa, ideal for securely pressing bearings and bushings into heavy metal housings.
Pallet Diverting
The 140 mm stroke provides the exact reach needed to push heavy pallets onto secondary packaging lines without requiring excessive retraction space.
Plastic Injection Unloading
SUS304 rod material withstands residual heat and occasional mold release spray, ensuring reliable extraction of large molded plastic components.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX140 the Right Cylinder?
Select this 100 mm bore when 80 mm hardware falls short, as stepping up from an 80 mm bore increases your 0.5 MPa push thrust from 2513 N to 3927 N. If your system requires holding a load during a pressure drop, the standard SAI will drift; you must specify the SAIL pneumatic lock or BSAI clamp-lock variant for fail-safe positioning.
This 140 mm stroke is well below the 1500 mm maximum standard stroke and operates at 30-800 mm/s. Being a true ISO 15552 profile cylinder, it serves as a drop-in replacement matching standard 100 mm bore dimensions, G1/2 port, and standard mounting accessories like FA flanges or TC trunnions.
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 SAI100BX140 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder yields 3927 N of push force and 3681 N of pull force. Raising pressure to 0.7 MPa increases the push output to 5497 N.
Yes. As a genuine ISO 15552 profile cylinder, its mounting interface, G1/2 port, and rod thread dimensions are standardized, allowing it to serve as a drop-in dimensional replacement for other ISO 15552 cylinders.
