About the Airtac SAI80 Standard Air Cylinder SAI80X350S
The AirTAC SAI80X350-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 350mm stroke. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it highly effective for moving substantial masses in automated lines. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 actuators.
Equipped with a magnetic piston (-S), this unit integrates seamlessly with CMSE and DMSE reed switches via the dual sensor grooves machined into both sides of the barrel. The standard carbon steel piston rod offers reliable durability for industrial duty cycles, while the adjustable air cushions at both ends ensure smooth deceleration of the 350mm travel.

Where the Airtac SAI80 Standard Air Cylinder SAI80X350S Is Used
Material Handling
Ideal for driving heavy pallet stops or mid-stroke gating mechanisms on high-throughput packaging conveyors where 2513 N of push force is required.
Automated Assembly
Provides the straight linear motion needed to press bearings or seat components securely into housings over a 350mm working distance.
Product Diverting
Handles the robust actuation required for pivoting heavy diverter arms on sorting lines, utilizing the magnetic piston for end-of-stroke confirmation.
Is the Airtac SAI80 Standard Air Cylinder SAI80X350S the Right Cylinder?
When sizing this actuator, note that stepping down to a 63mm bore reduces the 0.5 MPa push force to 1559 N, whereas moving up to a 100mm bore increases it to 3927 N. The 80mm bore provides an optimal middle ground for medium-to-heavy loads. Operating speed ranges from 30 to 800 mm/s, adjustable via flow controls and the end-of-stroke cushioning needles.
Because the 350mm stroke generates a long extension, the unsupported rod is susceptible to bending under side loads. For applications involving lateral forces, implement an external guide rail or utilize a dedicated guided cylinder to prevent premature rod-bearing wear. Additionally, this standard double-acting cylinder will drift if air pressure is lost; for position-holding requirements without live pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant. The PT tapered port and standardized mounting dimensions ensure easy drop-in compatibility with FA/LB foot and flange accessories.
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 SAI80X350S FAQ
At an operating pressure of 0.5 MPa, this 80mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes. The SAI80X350-S is built to the ISO 15552 standard, meaning its mounting interface and envelope dimensions are fully interchangeable with other ISO 15552 profile cylinders, allowing for a direct drop-in replacement.
