About the Airtac SAI100 Standard Air Cylinder SAI100BX225
The AirTAC SAI100X225 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 225mm stroke. It generates a substantial 3927 N of push force at 0.5 MPa, making it well-suited for heavy-duty positioning and high-inertia loads. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a piston magnet; if you need position detection, switch to the SAI100X225-S variant to utilize the dual-sided sensor grooves compatible with CMSE and DMSE switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX225 Is Used
Heavy Stamping
Provides the 3927 N push force at 0.5 MPa required to form and stamp thick metal components in automated fabrication lines.
Pallet Handling
Lifts and diverts heavy loaded pallets along high-throughput distribution conveyors without tie-rod interference.
Press Assembly
Applies steady clamping pressure to seat large bearings and housings during heavy mechanical assembly tasks.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX225 the Right Cylinder?
With a 225 mm stroke on a 100 mm bore, this cylinder handles large payloads but requires careful mounting to avoid rod-bearing bending under side loads. If your application involves heavy lateral forces, use an external guide rail or a dedicated guided cylinder. For applications needing slightly less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa. If you need to hold a load vertically without constant air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not function as a lock. For secure holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders, matching the 100mm bore, 225mm stroke, 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.
