About the Airtac SAI80 Standard Air Cylinder SAI80X300
The AirTAC SAI80X300 is a double-acting profile cylinder built to ISO 15552 dimensional standards, making it a drop-in replacement for any standard ISO 15552 interface. It delivers a robust 2513 N push force and 2268 N pull force at 0.5 MPa, fitting heavy-duty positioning tasks. The 300 mm stroke provides ample extension for mid-range automation cycles.
This genuine AirTAC unit features a standard carbon steel piston rod for high tensile strength under load. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches if a magnet is specified later. Adjustable air cushions at both ends decelerate the piston smoothly to prevent end-cap impact.

Where the Airtac SAI80 Standard Air Cylinder SAI80X300 Is Used
Automated Pressing
Provides 2513 N of thrust at 0.5 MPa for seating bearings, bushings, or rivets in automated assembly lines.
Product Diversion
The 300 mm stroke offers the reach needed to push heavy pallets or workpieces off a main conveyor belt.
Pallet Lift Stop
Acts as a high-force stop or lift mechanism for heavy pallets in materials handling and packaging systems.
Is the Airtac SAI80 Standard Air Cylinder SAI80X300 the Right Cylinder?
Select this 80 mm bore when 50 mm (982 N at 0.5 MPa) lacks the power to move your payload, but you want to avoid stepping up to the larger 100 mm bore. The G3/8 tapered PT port matches the required airflow for this volume. Because the stroke is 300 mm, the unsupported rod length is significant; lateral side loads will bend the rod bearing. Mount external guide rails or use a guided cylinder to prevent premature seal wear and rod deflection.
This standard cylinder relies on live air pressure to hold position. If your process drops pressure or centers the valve, the load will drift. For fail-safe holding, specify the SAIL variant with an air-released lock, or integrate an external rod 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 SAI80X300 FAQ
At 0.5 MPa, this cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 513 kgf.
Yes. The SAI80X300 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are interchangeable with other ISO 15552 cylinders. You can swap it directly using standard FA, FB, or LB mounting accessories.
