About the Airtac SAI80 Standard Air Cylinder SAI80BX70
The AirTAC SAI80X70 is a double-acting ISO 15552 profile cylinder engineered for robust actuation, delivering a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. With a 70 mm stroke, it is tailored for short-travel, high-thrust operations. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads for a reliable pneumatic connection. Note that this unit is supplied without a magnet; if position sensing is required, the dual sensor grooves on the barrel can be utilized by specifying the -S magnet option and CMSE or DMSE switches.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX70 Is Used
Heavy-Duty Clamping
Provides 2513 N of thrust at 0.5 MPa for securing thick metal plates during machining or welding operations.
Pallet Stopping
Acts as a robust stopper arm on heavy-duty roller conveyors, absorbing the impact of incoming pallets.
Press Fit Assembly
Delivers consistent downward force to press bearings or pins into housings over a 70 mm travel distance.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX70 the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant significantly increases thrust from 1559 N to 2513 N at 0.5 MPa, making it ideal for heavier payloads. Conversely, if your application requires less force, stepping down reduces physical size and air consumption. Because the 70 mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer strokes.
As a standard double-acting cylinder, the SAI80X70 relies on continuous air pressure to maintain its position; it will drift if pressure is lost. For applications requiring dead-stop holding without live air, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. Ensure your setup matches the PT G3/8 port and choose appropriate ISO 15552 mounting accessories like TC trunnion or FA flanges.
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 SAI80 Standard Air Cylinder SAI80BX70 FAQ
At 0.5 MPa, the SAI80X70 generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
No. The standard SAI80X70 is double-acting and will drift if air pressure is lost. For dead-load holding, use the SAIL (with lock) or BSAI (clamp-lock) variants.
