Where the Airtac SAI100 Standard Air Cylinder SAI100BX325 Is Used
Heavy Stamping
Provides the 3927 N force at 0.5 MPa needed to actuate heavy-duty stamping and forming presses.
Pallet Diversion
Handles large packaged goods or pallets along conveyor lines with a 325mm stroke for wide diversion arcs.
Automated Assembly
Drives heavy clamping fixtures on automated automotive assembly lines, utilizing its SUS304 rod for durability.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX325 the Right Cylinder?
When selecting this actuator, consider stepping down to a 63mm bore if your application only requires 1559 N of push force at 0.5 MPa, which saves space and air consumption. Conversely, if higher thrust is needed, the 125mm bore offers 6136 N. Because this 325mm stroke creates a long unsupported rod extension, side loads can cause rod-bearing bending and premature wear; using an external guide rail or a guided cylinder is highly recommended to prevent binding. If the machinery requires the load to be physically held in place during a pressure loss, note that the standard SAI piston will drift and drop; you must integrate an external pilot-operated check valve or specify the SAIL locking variant. This unit is dimensionally interchangeable per ISO 15552, so it serves as a drop-in replacement for other ISO 15552 cylinders with a 100mm bore, 325mm stroke, PT port thread, and standard mounting accessories like FA flanges.
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 SAI100 Standard Air Cylinder SAI100BX325 FAQ
At a 0.5 MPa operating pressure, the SAI100X325 generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
No, a standard double-acting SAI cylinder relies on air pressure and will drift or drop if pressure is lost. The adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. For vertical load holding, use the SAIL variant with an air-released lock or an external rod lock.
