About the Airtac SAI80 Standard Air Cylinder SAI80X135S
The AirTAC SAI80X135-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 135mm stroke. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for medium-to-heavy material handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting accessory installation.
Equipped with a magnetic piston (-S), this model directly supports CMSE and DMSE reed switches via the integrated sensor grooves on both sides of the barrel. The standard carbon steel piston rod ensures high tensile strength for demanding industrial cycles, while the adjustable air cushions at both ends absorb impact energy to maximize service life.

Where the Airtac SAI80 Standard Air Cylinder SAI80X135S Is Used
Automated Clamping Stations
Provides 2513 N of push force at 0.5 MPa to secure heavy metal castings during CNC machining operations.
Package Diverters
Uses the 135mm stroke to push heavy cartons between sorting lanes at speeds up to 800 mm/s.
Pallet Lifters
Lifts loaded pallets vertically, utilizing the integrated magnetic piston for precise end-of-stroke position detection.
Is the Airtac SAI80 Standard Air Cylinder SAI80X135S the Right Cylinder?
Select this 80mm bore cylinder when an application requires upward of 2500 N of push force at 0.5 MPa, or step down to the 63mm bore variant if your load only requires 1559 N. Conversely, if your fixture demands over 3500 N of push force at 0.7 MPa, consider upgrading to the 100mm bore size. The 135mm stroke offers a compact extension distance for clamping and lifting modules.
This unit uses a G3/8 PT tapered port and supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions. Because this is a standard double-acting cylinder, it relies entirely on live air pressure to move and hold loads; if your system loses air, the piston will drift. For dead-stop holding without continuous pressure, specify the SAIL pneumatic lock or BSAI clamp-lock variant instead.
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 SAI80X135S FAQ
