About the Airtac SAI100 Standard Air Cylinder SAI100BX225S
The AirTAC SAI100X225-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 225mm non-standard stroke. It delivers a robust push force of 3927 N at 0.5 MPa and a maximum theoretical thrust of 801 kgf at 1.0 MPa. The extended 225mm stroke is custom-engineered for machinery requiring precise intermediate linear positioning beyond standard increments.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically exposed settings. It is equipped with a magnetic piston (-S) for use with CMSE and DMSE sensor switches, which mount seamlessly into the dual sensor grooves machined into the extruded aluminum barrel. Fluid ports are PT tapered thread type.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX225S Is Used
Heavy-Duty Pressing
Ideal for applying 3927 N of force at 0.5 MPa for assembly operations, bearing insertion, and heavy component seating.
Material Diverting
Drives robust diverter arms and sorting gates on high-capacity packaging lines where a 225mm travel distance is required.
Washdown Automation
The SUS304 stainless steel rod provides excellent corrosion resistance for food processing and packaging machinery exposed to moisture.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX225S the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm variant upgrades your push force from 2513 N to 3927 N at 0.5 MPa, making it suitable for pressing heavier loads. If your application does not require this level of thrust, stepping down to the 80mm bore saves space and air consumption. Because the 225mm stroke is a made-to-order length, expect a brief lead time for manufacturing.
This model uses a G1/2 port and an M20x1.5 rod thread. Mounting accessories include FA, FB, LB, CA, CB, and TC styles to match your ISO 15552 interface requirements. Since the stroke exceeds 200mm, be mindful of side-load forces; an external guide rail or a guided cylinder carriage is strongly recommended to prevent the unsupported rod from bending and damaging the internal rod bearing. Note that the standard SAI does not hold position upon air loss; for dead-end holding, consider the SAIL variant or an external rod lock.
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 SAI100BX225S FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, the theoretical maximum force is 801 kgf.
Yes, the SAI profile barrel is dimensionally interchangeable per ISO 15552. You can swap it directly into existing machinery designed for standard ISO 15552 mounting interfaces without modifying the footprint.
