About the Airtac SAI80 Standard Air Cylinder SAI80X650S
The AirTAC SAI80X650-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and 650mm stroke. It delivers a robust 2513N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet enables direct mounting of CMSE or DMSE reed switches for precise end-of-stroke detection.
This model uses a standard carbon steel piston rod and PT tapered port threads. Adjustable air cushions at both ends manage piston deceleration across the 650mm travel distance. Operating speed spans 30-800 mm/s, providing rapid actuation for high-throughput machinery.

Where the Airtac SAI80 Standard Air Cylinder SAI80X650S Is Used
Heavy Stamping
Provides the 2513N force needed to actuate heavy stamping and forming presses.
Pallet Diverting
Handles large product or pallet diverting tasks along high-capacity conveyor lines.
Automated Bending
Powers robust automated bending arms that require sustained push strength over long strokes.
Is the Airtac SAI80 Standard Air Cylinder SAI80X650S the Right Cylinder?
Choose this 80mm bore when a 63mm cylinder lacks thrust—stepping down to a 63mm bore yields 1559N at 0.5 MPa, whereas this 80mm unit provides 2513N. For even higher force demands, a 100mm bore offers 3927N. Because the 650mm stroke is substantial, side loads can cause rod-bearing bending; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature wear.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders. To match this specific configuration, specify the 80mm bore, 650mm stroke, G3/8 port, TC trunnion or FA flange mounting, and the -S magnet option. If the application requires holding a load when air pressure is removed, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead of relying on the standard cushion.
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.
