About the Airtac SAI100 Standard Air Cylinder SAI100X270
The AirTAC SAI100X270 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. It yields a substantial 5497 N of push force at 0.7 MPa, making it well-suited for high-inertia automation tasks requiring a 270 mm travel distance. The extruded aluminum barrel omits tie rods, presenting a clean exterior that speeds up machine integration. Standard configuration includes a carbon steel piston rod for robust, everyday industrial durability. If your assembly line faces temperature extremes, you can specify Viton (H) seals instead of the standard TPU to maintain performance in hotter environments. This genuine AirTAC component ensures reliable, high-cycle operation.

Where the Airtac SAI100 Standard Air Cylinder SAI100X270 Is Used
Automotive Stamping
Provides the high push force required to seat heavy components and stamp automotive body panels within large fabrication presses.
Pallet Diverting
Actuates heavy-duty diverters on high-throughput packaging lines, moving fully loaded pallets laterally across conveyor belts.
Injection Molding Extraction
Drives robust robotic arms to extract molded parts from large injection molding machines, utilizing the full 270 mm stroke.
Is the Airtac SAI100 Standard Air Cylinder SAI100X270 the Right Cylinder?
With 5497 N of thrust at 0.7 MPa, this 100 mm bore size sits comfortably between the 63 mm bore (2182 N) and the 125 mm bore (8590 N), providing a solid balance of power and footprint for mid-to-large actuation. The 270 mm stroke falls below the 1500 mm maximum standard, but any stroke of this length requires careful attention to side-load management. An unsupported 270 mm rod can bend under lateral stress; utilize an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear. For applications that must hold a load vertically when air pressure is removed, note that the standard double-acting SAI will drift; you should specify an SAIL pneumatic lock or a BSAI clamp-lock variant instead. This unit features a PT tapered G1/2 port, standard carbon steel rod, and no magnet (-S) for sensor tracks.
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.
