About the Airtac SAI80 Standard Air Cylinder SAI80X280S
The AirTAC SAI80X280-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and 280mm stroke. It delivers a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. This specific configuration includes a built-in magnet for seamless integration with CMSE and DMSE sensor switches along the dual extruded barrel grooves.
Built with a standard carbon steel piston rod and PT tapered port threads, this model provides adjustable air cushioning at both ends to manage impact at cycle completion. As a genuine AirTAC component, it guarantees strict dimensional interchangeability with other ISO 15552 cylinders, allowing direct drop-in upgrades without altering existing mounting layouts.

Where the Airtac SAI80 Standard Air Cylinder SAI80X280S Is Used
Heavy Stamping
Provides the 2513 N push force required to actuate large mechanical presses and form rigid sheet metal components reliably.
Pallet Diverting
Leverages the 280mm stroke to push heavy pallets across high-throughput transfer lines without requiring multi-stage telescoping actuators.
Automated Clamping
Secures large machined castings inside CNC cells, using the integrated magnet and DMSE sensors to confirm clamping status before machining begins.
Is the Airtac SAI80 Standard Air Cylinder SAI80X280S the Right Cylinder?
Selecting this 80mm bore over the smaller 63mm option upgrades your thrust from 1559 N to 2513 N at 0.5 MPa, whereas stepping up to the 100mm bore would yield 3927 N. The 280mm stroke provides substantial travel distance while remaining within the 1500mm maximum standard limit.
Because the stroke is 280mm, the extended rod is susceptible to bending under heavy side loads. To protect the rod bearing and ensure longevity, implement an external guide rail or utilize a guided cylinder assembly. Note that the standard SAI does not hold position when air pressure is removed; for vertical loads requiring fail-safe holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. Replacement matching requires an 80mm bore, 280mm stroke, G3/8 port, and compatible TC trunnion or LB foot mounts.

- ✓ 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 SAI80X280S FAQ
