About the Airtac SAI80 Standard Air Cylinder SAI80X260
The AirTAC SAI80X260 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and 260mm stroke. It delivers a robust 2513N of push force at 0.5MPa, making it well-suited for heavy-duty positioning and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists contamination.
This specific configuration includes a standard carbon steel piston rod and PT tapered port threads. The barrel features dual-sided sensor grooves, allowing you to add CMSE or DMSE switches later if position detection becomes necessary for your automation cell.

Where the Airtac SAI80 Standard Air Cylinder SAI80X260 Is Used
Heavy-Duty Pressing
Ideal for applying consistent 2513N pressing forces in automated assembly lines and metal-forming stations.
Pallet Diverting
Provides the robust actuation needed to redirect heavy pallets or product totes on conveyor systems.
Parts Ejection
Delivers reliable kinetic energy to eject completed metal or plastic parts from molding and machining centers.
Is the Airtac SAI80 Standard Air Cylinder SAI80X260 the Right Cylinder?
Select this 80mm bore when a 63mm bore (providing 1559N push at 0.5MPa) is insufficient, but a 100mm bore (3927N) would be physically oversized. Because the 260mm stroke creates an extended lever arm, evaluate side loads carefully to prevent rod-bearing bending. For applications involving lateral forces, pair this cylinder with an external guide rail or utilize a dedicated guided cylinder.
This unit is dimensionally interchangeable per ISO 15552, offering a direct drop-in replacement for other standard profile cylinders. To match this specific configuration, specify an 80mm bore, 260mm stroke, G3/8 port, PT thread, and no magnet. Standard mounting accessories include FA/FB flanges and TC trunnion brackets. If your process requires the load to be held mechanically during air loss, consider the SAIL locking variant instead of relying on the standard adjustable air cushions.
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 SAI80X260 FAQ
At an operating pressure of 0.5MPa, the SAI80X260 generates 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
No, the standard SAI80X260 is double-acting and will drift if air pressure is lost. The adjustable air cushions only decelerate the piston at stroke ends. For true load holding, use the SAIL variant with an air-released lock.
