About the Airtac SAI100 Standard Air Cylinder SAI100X270S
The AirTAC SAI100X270-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 270mm stroke. It delivers a robust 5497 N of push force at 0.7 MPa, making it well-suited for heavy-duty material handling and pressing operations. The extruded aluminum barrel design omits tie rods, providing a clean exterior that easily drops into existing ISO 15552 mounting interfaces.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for position sensing. The dual sensor grooves on the barrel sides accept CMSE or DMSE reed switches, allowing for precise mid-stroke or end-position detection without requiring external mounting brackets.

Where the Airtac SAI100 Standard Air Cylinder SAI100X270S Is Used
Heavy Package Handling
Drives heavy pallets and large totes along sorting lines where high push force is required to overcome friction.
Assembly Pressing
Provides the consistent downward pressure needed for inserting bearings, bushings, or pins into housings.
Automated Clamping
Secures large metal or composite workpieces inside machining centers, holding firm against cutting forces.
Is the Airtac SAI100 Standard Air Cylinder SAI100X270S the Right Cylinder?
If 5497 N at 0.7 MPa is insufficient, stepping up to the 125mm bore yields 8590 N, while dropping to the 80mm bore reduces output to 3518 N. At 270mm of stroke, the unsupported piston rod is susceptible to bending under lateral loads; utilize an external guide rail or a guided cylinder to prevent rod-bearing wear.
For applications requiring the load to remain suspended during a pressure loss event, the standard SAI will drift. Specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock to maintain position safely. This unit uses a PT tapered G1/2 port and is dimensionally interchangeable with other ISO 15552 cylinders.

- ✓ 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 SAI100X270S FAQ
