About the Airtac SAI100 Standard Air Cylinder SAI100BX260
The AirTAC SAI100X260 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100mm bore unit is built to handle substantial loads across its 260mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or washdown environments. It utilizes PT tapered G1/2 ports and lacks a standard magnet. For applications requiring position holding without air pressure, the SAIL variant with an air-released lock is recommended over the standard model.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX260 Is Used
Heavy Stamping
Provides the high thrust needed for pressing and stamping rigid metal or plastic components in automated assembly lines.
Pallet Diversion
Actuates heavy-duty diverter arms to redirect loaded pallets along material handling conveyors.
Plastic Molding
Operates large clamps and ejection mechanisms in injection molding cells requiring reliable high-force linear motion.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX260 the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when your application requires upward of 3927 N of thrust at 0.5 MPa. If your force requirements are lower, stepping down to an 80mm bore provides 2513 N, which may save space and air consumption. Conversely, moving up to a 125mm bore yields 6136 N for heavier loads.
Because the 260mm stroke is substantial, avoid using the piston rod to absorb direct side loads. Long unsupported rods are prone to bending under lateral forces, so utilize external guide rails or a guided cylinder mechanism to protect the rod bearing and seals. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard cylinder sharing these exact mounting dimensions, G1/2 ports, and 100x260 specifications.
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 SAI100BX260 FAQ
At 0.5 MPa operating pressure, the SAI100X260 generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X260 is dimensionally interchangeable per ISO 15552 standards. It shares identical mounting interfaces, G1/2 ports, and 100mm bore dimensions with other standard profile cylinders, allowing for seamless drop-in replacement.
