About the Airtac SAI80 Standard Air Cylinder SAI80X240
The AirTAC SAI80X240 is a double-acting ISO 15552 profile cylinder offering a robust 2513 N push force at 0.5 MPa and 2268 N pull force. Its 240 mm stroke handles substantial linear motion tasks requiring high thrust. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This unit features a standard carbon steel piston rod and utilizes a PT G3/8 tapered port thread. Because a magnet is not specified, it operates without integrated sensor detection. For applications requiring high-temperature resilience up to +70 C, the seals can be specified in Viton (H) or NBR (N) instead of the standard TPU.

Where the Airtac SAI80 Standard Air Cylinder SAI80X240 Is Used
Heavy Stamping
Provides the high 2513 N push force needed to actuate heavy-duty stamping and forming presses.
Pallet Diverting
Extends 240 mm to push and divert heavy pallets along high-throughput packaging and distribution lines.
Material Lift
Raises substantial material weights in automated assembly lines where 0.5 MPa yields ample lifting power.
Is the Airtac SAI80 Standard Air Cylinder SAI80X240 the Right Cylinder?
Choose this 80 mm bore when a 63 mm bore (providing 1559 N at 0.5 MPa) lacks sufficient thrust, but a 100 mm bore (3927 N) would be excessive overkill. The 240 mm stroke is a standard length, but because it exceeds 300 mm is not an issue here, the rod bearing handles the load well without requiring external guides.
As a standard double-acting cylinder, it relies on live air pressure to maintain its position. If your system loses air or the valve centers, the piston will drift and drop. To hold a load securely without continuous pressure, integrate an external pilot-operated check valve or select the SAIL (air-released lock) or BSAI (clamp-lock) 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.
