About the Airtac SAI80 Standard Air Cylinder SAI80X185S
The AirTAC SAI80X185-S is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513 N of push force at 0.5 MPa. With an 80 mm bore and 185 mm stroke, this extruded aluminum actuator is built for demanding mid-to-heavy industrial tasks.
Equipped with an integrated magnet (-S), the barrel features dual sensor grooves designed for seamless CMSE and DMSE switch mounting. The standard carbon steel piston rod provides durable performance, while adjustable air cushions at both ends ensure smooth deceleration across its 30-800 mm/s operating speed range.

Where the Airtac SAI80 Standard Air Cylinder SAI80X185S Is Used
Heavy-Duty Clamping
Secures large steel plates during machining operations, utilizing its 2513 N push force to prevent workpiece shifting under high cutting loads.
Pallet Diverting
Actuates heavy diverters on high-throughput packaging lines, where the 185 mm stroke quickly pushes loaded pallets onto secondary tracks.
Press Ejection
Ejects formed metal components from hydraulic presses, benefiting from the adjustable end cushions to protect delicate tooling during rapid retraction.
Is the Airtac SAI80 Standard Air Cylinder SAI80X185S the Right Cylinder?
Select this 80 mm bore when an application requires significantly more thrust than a 63 mm cylinder (which provides 1559 N at 0.5 MPa), but without the larger footprint of a 100 mm unit. The 185 mm stroke offers ample extension for clamping and lifting tasks. Because the stroke is under 300 mm, side-load stress on the rod bearing remains minimal compared to longer extensions.
This model uses a G3/8 PT tapered port. It serves as a drop-in replacement for any true ISO 15552 cylinder, matching standard mounting dimensions for FA, FB, LB, CA, CB, and TC accessories. Remember that the standard SAI relies entirely on air pressure to hold its load; if your system loses pressure, the piston will drift. For dead-load holding, consider the SAIL variant with an air-released lock.
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 SAI80X185S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. If operating pressure increases to 0.7 MPa, the push force rises to 3518 N.
Yes. The SAI80X185-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders from brands like Festo or SMC. It matches standard mounting interfaces and utilizes a G3/8 PT port.
