About the Airtac SAI50 Standard Cylinder SAI50AX275
The AirTAC SAI50X275 is a double-acting profile cylinder that strictly adheres to the ISO 15552 mounting interface, making it a direct replacement for other ISO 15552 cylinders. Operating on filtered air, it generates a push force of 982 N and a pull force of 825 N at 0.5 MPa. The 275 mm stroke provides ample travel for intermediate linear actuation tasks.
This specific unit is configured with an SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. Because it lacks the -S magnet option, it does not have integrated sensor grooves for reed switches. For environments requiring higher temperatures, the standard TPU seals can be swapped for Viton (H) alternatives.

Where the Airtac SAI50 Standard Cylinder SAI50AX275 Is Used
Package Sorting Diverter
Provides the 982 N force needed to push medium-weight parcels off a main conveyor line at high cycling rates.
Clamping Fixture
Secures workpieces during secondary machining operations, using the 275 mm stroke to accommodate varying part widths.
Pallet Stops
Acts as a robust physical stop mechanism for pallets entering a wrapping station, absorbing kinetic energy safely.
Is the Airtac SAI50 Standard Cylinder SAI50AX275 the Right Cylinder?
Selecting this 50 mm bore over the smaller 40 mm bore upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to the 63 mm bore yields 1559 N. Since the 275 mm stroke exceeds 300 mm, be aware that long unsupported rods are susceptible to bending under side loads; utilizing an external guide or a guided cylinder is recommended to prevent premature rod-bearing wear.
Ensure your replacement matches the exact ISO 15552 dimensions: 50 mm bore, 275 mm stroke, PT G1/4 port, and your required mounting accessory like an FA flange or LB foot. Note that a standard SAI does not maintain its position when air pressure is lost; if your application requires dead-end holding, consider the SAIL (with air-released lock) or BSAI (bidirectional clamp-lock) 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 SAI50 Standard Cylinder SAI50AX275 FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At the maximum 1.0 MPa pressure, the theoretical push force reaches 1767 N.
Yes. The SAI series is a genuine ISO 15552 profile cylinder, meaning it is dimensionally interchangeable with other ISO 15552 cylinders of the same 50 mm bore and 275 mm stroke configuration.
