About the Airtac SAI80 Standard Air Cylinder SAI80X500S
The AirTAC SAI80X500-S is a double-acting ISO 15552 profile cylinder engineered for rigorous pneumatic tasks. It provides a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for heavy material handling over its 500 mm stroke. The extruded aluminum barrel omits tie rods for a clean exterior.
Equipped with a factory-installed magnet (-S), this model directly supports CMSE and DMSE sensor switches via integrated grooves on both sides of the barrel. The standard carbon steel piston rod ensures high tensile strength, while the adjustable air cushions at both ends deliver precise end-of-stroke deceleration. It features a G3/8 PT tapered port thread for reliable pneumatic plumbing.

Where the Airtac SAI80 Standard Air Cylinder SAI80X500S Is Used
Heavy Stamping
Provides the 2513 N push force required to actuate heavy-duty stamping and forming presses over a 500 mm travel distance.
Pallet Diverting
Ideal for diverting large pallets on conveyor lines, utilizing the full 500 mm stroke and integrated CMSE sensors for position confirmation.
Automated Assembly
Drives large-format clamping and lifting fixtures in automated assembly cells where robust 80 mm bore power is necessary.
Is the Airtac SAI80 Standard Air Cylinder SAI80X500S the Right Cylinder?
Selecting this 80 mm bore over the neighboring 63 mm variant yields a significant thrust increase, stepping up from 1559 N to 2513 N at 0.5 MPa. If your application demands less force, dropping to the 63 mm bore can save space and air consumption. This 500 mm stroke requires careful mounting to prevent rod-bearing bending under side loads; utilizing external guide rails or a guided cylinder carriage is strongly recommended to maintain alignment and prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard brands using identical mounting interfaces. To secure this unit, use FA or FB flange accessories, LB foot brackets, or TC trunnion mounts. Remember that the standard double-acting configuration relies on continuous air pressure; if a load must be held safely during an air loss event, integrate an external pilot-operated check valve or select the SAIL or BSAI locking variants.
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 SAI80X500S FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder 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.
Yes, the SAI80X500-S is a true ISO 15552 profile cylinder. It shares the standardized mounting interface and physical envelope of other ISO 15552 cylinders, allowing it to serve as a drop-in replacement without modifying the machine frame.
