About the Airtac SAI80 Standard Air Cylinder SAI80X325
The AirTAC SAI80X325 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513 N of push force at 0.5 MPa. Its 325 mm stroke provides the extended travel needed for mid-distance indexing and heavy part manipulation. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that simplifies mounting and sensor placement.
Equipped with standard carbon steel piston rod material, this unit handles demanding industrial environments. The barrel features dual-sided sensor grooves, allowing you to easily integrate CMSE or DMSE switches if you later require position feedback. It utilizes a PT tapered port thread type (G3/8) to ensure a secure, leak-free pneumatic connection.

Where the Airtac SAI80 Standard Air Cylinder SAI80X325 Is Used
Pallet Transfer
Provides the extended 325 mm reach and 2513 N push force required to index heavy loaded pallets between processing stations.
Material Lift
Lifts heavy automotive subcomponents vertically, relying on adjustable air cushions to soften the impact at the top of the stroke.
Clamp Actuation
Drives large machining clamps with high force, ensuring rigid workholding for heavy-duty milling operations.
Is the Airtac SAI80 Standard Air Cylinder SAI80X325 the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant jumps your push thrust from 1559 N to 2513 N at 0.5 MPa, which is critical if you are moving heavier pallets or overcoming high friction. Conversely, if your load is lighter, stepping down to the 63 mm bore saves air consumption and cycle time.
Because the 325 mm stroke creates a long unsupported rod extension, side loads can cause rod-bearing bending and premature wear. Use an external guide rail or a guided cylinder carriage to absorb lateral forces. Note that the standard adjustable air cushions only decelerate the piston at stroke ends; if your system must hold a load vertically when air pressure drops, specify the SAIL (air-released lock) variant or an external rod 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 SAI80X325 FAQ
At 0.5 MPa operating pressure, the SAI80X325 generates 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 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 80 mm bore, 325 mm stroke, G3/8 port, and your required mounting accessory.
