About the Airtac SAI80 Standard Air Cylinder SAI80X180
The AirTAC SAI80X180 is a double-acting ISO 15552 profile cylinder engineered to deliver robust linear motion. Operating at 0.15-1.0 MPa, it generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it well-suited for heavy material handling tasks requiring a 180 mm stroke.
This standard profile-barrel unit features a carbon steel piston rod for durable daily operation. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches when position feedback is required. Adjustable air cushions at both ends ensure smooth deceleration of the 30-800 mm/s operating speed.

Where the Airtac SAI80 Standard Air Cylinder SAI80X180 Is Used
Heavy Material Handling
Ideal for pushing or lifting heavy pallets and chassis components where 2513 N of thrust at 0.5 MPa is required.
Pallet Diverting
Provides the robust actuation force needed to divert heavy goods on conveyor lines across a 180 mm travel range.
Press Operations
Suitable for light-duty pressing and stamping tasks, utilizing the 80 mm bore's high force output and adjustable cushions.
Is the Airtac SAI80 Standard Air Cylinder SAI80X180 the Right Cylinder?
Select this 80 mm bore when an application demands more thrust than the 63 mm bore (which provides 1559 N push at 0.5 MPa) but does not require the full 3927 N output of the 100 mm variant. The 180 mm stroke is optimal for medium-travel indexing. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for heavy lateral loads.
Ensure a drop-in replacement by matching the 80 mm bore, 180 mm stroke, G3/8 PT port threads, and appropriate mounting accessories like FA/FB flanges or TC trunnions. Note that the standard double-acting design relies on continuous air pressure; if a machine loses air, the piston will drift. For dead-stop load holding without live pressure, integrate an external pilot-operated check valve or select the SAIL variant with an air-released 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 SAI80X180 FAQ
At 0.5 MPa operating pressure, the SAI80X180 delivers 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes. The SAI80X180 is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders with an 80 mm bore, 180 mm stroke, and G3/8 ports.
