About the Airtac SAI100 Standard Air Cylinder SAI100BX270
The AirTAC SAI100X270 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa. Its 270 mm stroke handles substantial linear motion tasks with ease. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a SUS304 stainless steel piston rod (material code B), making it highly suitable for environments where corrosion resistance is paramount. It uses PT tapered G1/2 ports and lacks a standard magnet, though the barrel includes dual-side sensor grooves should you later need to integrate CMSE or DMSE switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX270 Is Used
Automotive Assembly Press
Drives heavy jigs and clamps vehicle components securely on the production line using its 3927 N push force.
Pallet Diverters
Actuates heavy-duty diverter arms to route loaded pallets through high-throughput material handling systems.
Plastic Injection Unloading
Extracts molded parts from machinery, leveraging the SUS304 rod for resistance against humid or chemically washed environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX270 the Right Cylinder?
Providing 3927 N of thrust at 0.5 MPa, this 100 mm bore is a significant step up from the 63 mm bore (1559 N) for heavier machinery, while avoiding the massive 125 mm bore (6136 N) which may be overkill and consume excess air. Because this 270 mm stroke exceeds 300 mm is not yet reached, but side-load management remains critical: long unsupported rods bend under lateral forces, so utilize external guides or a guided cylinder to protect the rod bearing.
For drop-in replacements, match the 100 mm bore, 270 mm stroke, PT G1/2 port, and your required mounting accessory (such as an LB foot or FA flange). If your machinery requires intermediate stopping or position holding without live air pressure, a standard SAI will drift; instead, specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
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 SAI100BX270 FAQ
At an operating pressure of 0.5 MPa, 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, the SAI100X270 is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders by matching the 100 mm bore, 270 mm stroke, and G1/2 port dimensions.
