About the Airtac SAI80 Standard Air Cylinder SAI80X900
The AirTAC SAI80X900 is a double-acting ISO 15552 profile cylinder engineered for substantial actuation tasks, delivering 2513 N of push force at 0.5 MPa. Its extruded aluminum barrel design omits tie rods, providing a smooth exterior that integrates seamlessly into modern machinery.
This 900 mm stroke variant is equipped with a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, users requiring position feedback must specify the -S option, though the barrel retains dual sensor grooves for CMSE or DMSE switches if upgraded later.

Where the Airtac SAI80 Standard Air Cylinder SAI80X900 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 900 mm gap, utilizing the 2513 N thrust at 0.5 MPa to overcome friction on roller conveyors.
Vertical Lift Gates
Actuates large access doors or lifting platforms where the extensive stroke is required, provided an external guide supports the load.
Large Assembly Press
Drives heavy-duty seating or pressing stations, relying on the 80 mm bore's 3518 N output at 0.7 MPa to seat large mechanical components.
Is the Airtac SAI80 Standard Air Cylinder SAI80X900 the Right Cylinder?
Selecting this 80 mm bore unit makes sense when 50 mm bore cylinders (providing 982 N at 0.5 MPa) lack the necessary thrust, but a 100 mm bore (3927 N at 0.5 MPa) would be physically oversized. At 900 mm of stroke, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder configuration is strongly recommended to prevent premature rod-bearing wear.
As an ISO 15552 standard cylinder, it serves as a drop-in dimensional replacement for comparable profile cylinders, matching the 80 mm bore, 900 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston at end-of-stroke and cannot hold a load vertically if air pressure is lost; for dead-load holding, specify an SAIL or BSAI locking 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 SAI80X900 FAQ
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. If operated at 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X900 is dimensionally interchangeable per ISO 15552. It shares standard mounting dimensions and G3/8 ports with other 80 mm profile cylinders, allowing direct drop-in replacement.
