About the Airtac SAI80 Standard Air Cylinder SAI80X1800S
The AirTAC SAI80X1800-S is a double-acting ISO 15552 profile cylinder engineered for an extended 1800mm stroke. It delivers a robust 3518N of push force at 0.7 MPa, making it highly capable of moving substantial masses over long linear distances. Because the requested stroke exceeds the standard 1500mm maximum for this bore, it is manufactured as a made-to-order unit to exact application specifications.
This variant includes a magnetic piston for position sensing, seamlessly integrating with CMSE or DMSE reed switches along the extruded aluminum barrel grooves. It comes equipped with a standard carbon steel piston rod and PT tapered port threads, ensuring reliable sealing and rugged performance in demanding industrial environments.

Where the Airtac SAI80 Standard Air Cylinder SAI80X1800S Is Used
Long-Stroke Material Transfer
Ideal for pushing heavy pallets or workpieces across 1.8-meter spans where a standard stroke falls short, utilizing the 3518N force to overcome friction.
Large Press Ejection
Ejects bulky formed parts from large stamping presses, using the extended reach to clear the press bed entirely before the robot unloads the part.
Automated Storage Retrieval
Acts as a horizontal extractor in automated storage systems, reaching deep into racking to pull heavy totes into the transfer conveyor.
Is the Airtac SAI80 Standard Air Cylinder SAI80X1800S the Right Cylinder?
When specifying this 80mm bore unit, verify if the 2513N push force at 0.5 MPa is sufficient, or if stepping up to the 100mm bore (3927N at 0.5 MPa) is necessary for heavier loads. At a 1800mm stroke, the unsupported piston rod is highly susceptible to bending under side load. You must use an external guide rail or a fully guided cylinder to prevent rod-bearing damage and premature seal failure.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. It uses a G3/8 port, an M20x1.5 rod thread, and pairs with FA/FB flanges or TC trunnion mounts. To hold a load safely without live air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the standard adjustable air cushions, which only decelerate the piston at end-of-stroke.
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.
