About the Airtac SAI80 Standard Air Cylinder SAI80X325S
The AirTAC SAI80X325-S is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force at 0.5 MPa. Its 325 mm stroke provides the extended travel needed for sizable material handling tasks. As a genuine AirTAC component, it guarantees dimensional interchangeability with other ISO 15552 profile cylinders.
This specific configuration includes a standard carbon steel piston rod and a magnetic piston for position detection. The -S designation means it is ready to accept CMSE or DMSE sensor switches, which seat directly into the dual grooves machined into the extruded aluminum barrel.

Where the Airtac SAI80 Standard Air Cylinder SAI80X325S Is Used
Pallet Diversion
Provides the extended 325 mm reach and 2513 N force required to push heavy pallets onto secondary packaging lines.
Automated Pressing
Applies consistent downward pressure for assembling large components, utilizing adjustable cushions to protect the tooling at stroke end.
Vertical Lifting
Raises heavy tote bins to unloading heights; pair with a guided carriage to prevent torsional damage during the 325 mm lift.
Is the Airtac SAI80 Standard Air Cylinder SAI80X325S the Right Cylinder?
Select this 80 mm bore when an application requires more power than a 63 mm variant, which offers 1559 N at 0.5 MPa, but does not need the full 3927 N output of a 100 mm unit. Because the 325 mm stroke creates a long unsupported rod extension, you must manage side loads to prevent rod-bearing bending; use an external guide rail or select a fully guided cylinder for heavy off-center loads.
This model features G3/8 PT tapered ports and adjustable air cushions at both ends to decelerate the piston smoothly. Note that the standard SAI does not hold its position if air pressure is lost; for suspended loads requiring fail-safe holding, specify the SAIL lock or BSAI clamp-lock 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 SAI80X325S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X325-S shares the exact ISO 15552 mounting interface and dimensions, allowing it to serve as a drop-in replacement for comparable profile cylinders. It uses a G3/8 PT port and an M20x1.5 rod thread.
