About the Airtac SAI80 Standard Air Cylinder SAI80X550S
The AirTAC SAI80X550-S is a double-acting ISO 15552 profile cylinder offering a robust 2513N push force at 0.5 MPa. With a 550mm stroke, this genuine AirTAC actuator is built for long-travel automation tasks requiring substantial reach and power. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies cleaning and maintenance in demanding industrial environments.
Equipped with a standard magnet (-S), this model directly supports CMSE and DMSE electronic sensor switches via the integrated mounting grooves on both sides of the barrel. The piston rod utilizes durable carbon steel for high tensile strength, while the adjustable air cushions at both ends ensure smooth deceleration of moving masses across the extended 550mm travel distance.

Where the Airtac SAI80 Standard Air Cylinder SAI80X550S Is Used
Long-Stroke Material Handling
Ideal for pushing heavy pallets or transferring products across 550mm gaps in automated packaging lines where 2513N of thrust is required.
Heavy Pressing Operations
Provides the sustained downward force needed for medium-duty pressing, stamping, or assembly tasks without requiring a full hydraulic system.
Automated Storage Retrieval
The integrated magnet and dual sensor grooves allow precise end-of-stroke detection for 550mm extraction movements in ASRS shuttle mechanisms.
Is the Airtac SAI80 Standard Air Cylinder SAI80X550S the Right Cylinder?
If your application requires less force, stepping down to the 63mm bore variant yields a 1559N push capacity at 0.5 MPa, which may suffice for lighter loads. However, for heavy lifting and high thrust over long reaches, this 80mm bore is optimal. Because the 550mm stroke creates a long unsupported rod extension, side loads can cause severe rod-bearing bending. To mitigate premature seal wear and piston drift, mount an external guide rail or select a dedicated guided cylinder to handle lateral forces.
This model features a G3/8 PT tapered port and a 25mm piston rod. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 actuators, matching standard mounting footprints like the LB trunnion or FA flange. Note that standard air cushions only decelerate the piston; they do not hold a load. If your system loses pressure, the rod will drift. For position holding without live air, consider the SAIL locking variant or an external pilot-operated check valve.
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 SAI80X550S FAQ
At a 0.5 MPa operating pressure, this 80mm bore cylinder generates a push force of 2513N and a pull force of 2268N. At the maximum 1.0 MPa pressure, the theoretical push force reaches 513 kgf.
Yes, the SAI80X550-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting interfaces using standard LB, FA, or TC accessories without modifying the machine frame.
