About the Airtac SAI100 Standard Air Cylinder SAI100BX240S
The AirTAC SAI100X240-S is a double-acting ISO 15552 profile cylinder engineered to deliver robust linear motion. It provides a substantial push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for heavy-duty handling tasks requiring a 240 mm stroke.
Equipped from the factory with a SUS304 stainless steel rod (option B), this unit offers superior corrosion resistance for demanding environments. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE switches housed within the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX240S Is Used
Heavy Stamping
Provides the necessary 3927 N push force at 0.5 MPa to actuate heavy-duty stamping and forming presses reliably.
Pallet Diverting
Drives robust routing arms on high-mass conveyor lines, using the 240 mm stroke to shift pallets efficiently.
Material Clamping
Secures large workpieces during machining operations, utilizing the SUS304 rod for resilience in harsh industrial fluids.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX240S the Right Cylinder?
Selecting this 100 mm bore makes sense when a 63 mm bore falls short, as the 63 mm variant yields only 1559 N of push force at 0.5 MPa. If your application requires less energy, stepping down to an 80 mm bore provides 2513 N, balancing power and air consumption more efficiently.
Because the 240 mm stroke places lateral stress on the rod bearing during extension, utilizing an external guide rail or a guided cylinder is recommended to prevent side-load bending. This genuine AirTAC component features PT tapered ports and mounts via standard ISO 15552 accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston at end-of-stroke; to safely hold a load without live air pressure, specify an SAIL or BSAI locking variant.
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 SAI100BX240S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. If pressure increases to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X240-S adheres strictly to ISO 15552 dimensional standards. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 100 mm bore, 240 mm stroke, and G1/2 port interface.
