About the Airtac SAI100 Standard Air Cylinder SAI100BX300
The AirTAC SAI100X300 is a double-acting ISO 15552 profile cylinder engineered to deliver 3927 N of push force and 3681 N of pull force at 0.5 MPa. With a 300 mm stroke, it is built for heavy-duty positioning and high-inertia automation tasks.
This specific configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance in washdown or chemically active settings. Fluid flow is managed via a tapered PT G1/2 port, and the extruded aluminum barrel includes dual sensor grooves ready for CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX300 Is Used
Heavy Stamping Press
Provides 3927 N of thrust at 0.5 MPa to actuate large forming dies and heavy-duty stamping assemblies.
Pallet Diversion
Extends 300 mm to push heavy pallets onto secondary packaging lines with high kinetic stability.
Automated Welding Gate
Shifts large welding fixtures into position, utilizing the SUS304 rod to resist weld spatter and plant humidity.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX300 the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant steps the 0.5 MPa push force up from 2513 N to 3927 N, providing the necessary thrust for heavier platens. If your application requires even more power, stepping up to the 125 mm bore yields 6136 N at the same pressure.
Because the 300 mm stroke creates an extended lever arm, side loads can cause severe rod-bearing bending and premature wear. Implement an external guide rail or select a guided cylinder to absorb radial loads and protect the piston rod. Note that the adjustable air cushions only decelerate the piston near stroke end; if pressure is lost, the load will drop. For position holding without live air, utilize the SAIL (lock) or BSAI (clamp-lock) variant. This model is a dimensional drop-in replacement per ISO 15552 mounting interface standards.
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 SAI100BX300 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes. It is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders using standard mounting accessories like FA flanges or TC trunnions.
