About the Airtac SAI100 Standard Air Cylinder SAI100AX270S
The AirTAC SAI100X270-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N push force at 0.5 MPa, this 100mm bore unit is built to drive substantial masses through a 270mm stroke. The extruded aluminum barrel omits tie rods, presenting a clean exterior that drops right into standardized ISO 15552 mounting footprints.
This specific configuration includes a -S magnet for direct CMSE and DMSE sensor integration along the dual barrel grooves. The piston rod is constructed from SUS420J2 stainless steel (option A) for superior corrosion resistance, and fluid connections use PT tapered threads. Standard adjustable air cushions at both ends absorb impact energy, operating reliably at speeds between 30-800 mm/s.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX270S Is Used
Heavy-Duty Pressing
Ideal for applying 3927 N of thrust at 0.5 MPa to seat bearings, form light gauge metals, or assemble heavy housings on a production line.
Pallet Diverting
Provides the robust reach and force needed to redirect large, loaded pallets at transfer stations using a 270mm stroke.
Automated Welding Clamp
The SUS420J2 stainless rod offers good resistance to weld spatter while holding heavy structural frames firmly in place.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX270S the Right Cylinder?
Selecting this 100mm bore over the 80mm version makes sense when your application requires moving from 2513 N to 3927 N of push force at 0.5 MPa. At a 270mm stroke, the unsupported rod length is moderate, but you must still account for potential side-load bending on the rod bearing; utilizing an external guide rail or a fully guided cylinder ensures precise, friction-free motion.
Because this is a standard double-acting cylinder, it will not hold a load in place if air pressure is lost or the control valve is centered. For vertical loads requiring safety locking during an air failure, consider the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock. To replace an existing actuator, match the 100mm bore, 270mm stroke, G1/2 port, and TC or FA mounting accessories.
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 SAI100AX270S FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. It can reach up to 5497 N push force at 0.7 MPa.
Yes. As a genuine ISO 15552 profile cylinder, its mounting dimensions are fully interchangeable with other ISO 15552 cylinders, allowing a direct drop-in replacement without modifying your machine plate.
