About the Airtac SAI80 Standard Air Cylinder SAI80X350
The AirTAC SAI80X350 is a double-acting ISO 15552 profile cylinder offering a robust 2513 N push force at 0.5 MPa. Its 350 mm stroke is well-suited for medium-to-long travel indexing and material transfer tasks. The extruded aluminum barrel eliminates tie-rods, presenting a clean exterior that resists contamination.
This model features a standard carbon steel piston rod for high tensile strength in demanding industrial environments. Because a magnet is not specified, it does not have sensor grooves populated; if position detection is required later, the -S variant with CMSE or DMSE switches is necessary.

Where the Airtac SAI80 Standard Air Cylinder SAI80X350 Is Used
Pallet Transfer
Provides the 2513 N force needed to push heavy pallets securely onto downstream processing conveyors over a 350 mm gap.
Press Ejection
Ejects machined or stamped components from press beds, utilizing the 350 mm stroke to clear the tooling area completely.
Vertical Lifting
Raises lightweight material handling lifts or shuttle trolleys, taking advantage of the 80 mm bore capacity at standard shop air pressures.
Is the Airtac SAI80 Standard Air Cylinder SAI80X350 the Right Cylinder?
Stepping down to the 63 mm bore drops the 0.5 MPa push force to 1559 N, which may be insufficient for heavier 80 mm class payloads. Conversely, moving up to the 100 mm bore increases the 0.5 MPa push force to 3927 N for high-inertia loads. The PT tapered port thread is G3/8, and standard mounting accessories include FA/FB flanges or TC trunnion brackets.
At 350 mm of travel, the unsupported piston rod is susceptible to bending under side loads. Employ an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear. Note that this standard cylinder relies on live air pressure to hold position; if the air is exhausted, the load will drift. For fail-safe holding without pressure, specify 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 SAI80X350 FAQ
At 0.5 MPa, this 80 mm bore cylinder generates a pushing force of 2513 N and a pulling force of 2268 N.
Yes, the SAI80X350 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided you match the 80 mm bore and 350 mm stroke.
