About the Airtac SAI80 Standard Air Cylinder SAI80X270S
The AirTAC SAI80X270-S is a double-acting ISO 15552 profile cylinder engineered for demanding 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 mid-stroke actuation requiring substantial power. The 270 mm stroke handles extended travel without sacrificing stability.
This model includes a magnet for proximity sensing and utilizes a standard carbon steel piston rod for reliable durability. It features a PT tapered port thread and integrated adjustable air cushioning at both ends to manage impact deceleration. The extruded aluminum barrel offers dual sensor grooves, allowing seamless mounting of CMSE or DMSE switches along the cylinder body.

Where the Airtac SAI80 Standard Air Cylinder SAI80X270S Is Used
Clamping Heavy Fixtures
Ideal for securing heavy metal components during machining operations, utilizing its 2513 N push force to maintain rigid clamping pressure throughout the manufacturing cycle.
Pallet Diverter
Acts as a robust diverter mechanism on automated packaging lines, using the 270 mm stroke to push heavy pallets onto secondary processing tracks with reliable speed.
Press Operations
Suitable for light-duty pressing and stamping tasks where consistent downward force and adjustable end-cushioning protect the assembly from sudden impact damage.
Is the Airtac SAI80 Standard Air Cylinder SAI80X270S the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant makes sense when your application requires moving from 1559 N to 2513 N of push force at 0.5 MPa. Conversely, if your load demands even higher energy, stepping up to the 100 mm bore yields 3927 N. Because this model features a 270 mm stroke, supporting the load with an external guide or a dedicated guided cylinder is recommended to prevent rod-bearing bending under side loads.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard ISO 15552 cylinders. To match this exact configuration, specify the 80 mm bore, 270 mm stroke, PT G3/8 port, foot or flange mounting accessory, and the -S magnet option. Note that the standard SAI does not hold position upon air loss; for fail-safe load holding, consider the SAIL or BSAI variant.
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 SAI80X270S 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. If pressure is increased to 0.7 MPa, the push force rises to 3518 N.
Yes, the SAI80X270-S is a genuine ISO 15552 profile cylinder, meaning its mounting interface is dimensionally interchangeable with other ISO 15552 cylinders. You can use it as a drop-in replacement by matching the 80 mm bore, 270 mm stroke, and G3/8 port.
