About the Airtac SAI100 Standard Air Cylinder SAI100X325
The AirTAC SAI100X325 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit utilizes a 325 mm stroke to drive substantial loads through extended cycles. The extruded aluminum barrel design eliminates protruding tie rods, providing a clean exterior that simplifies mounting and accessorizing.
This specific configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks the -S magnet option, it operates without integrated sensor tracks, relying purely on its mechanical output. For high-temperature environments up to +70 C, the standard TPU seals handle the demands well, though Viton (H) alternatives exist for more extreme thermal conditions.

Where the Airtac SAI100 Standard Air Cylinder SAI100X325 Is Used
Heavy Stamping
Drives large press dies and stamping fixtures requiring high kinetic energy and 3927 N of thrust at 0.5 MPa.
Pallet Diversion
Actuates heavy-duty lane diverters and pallet stops using its 325 mm stroke to reposition large goods.
Automated Assembly
Pushes substantial subassemblies or heavy components into machining centers along guided rails.
Is the Airtac SAI100 Standard Air Cylinder SAI100X325 the Right Cylinder?
Selecting this 100 mm bore makes sense when a 80 mm cylinder's 2513 N at 0.5 MPa is insufficient, but you want to avoid the added mass of a 125 mm unit. The 325 mm stroke provides ample extension for material handling, but at this length the unsupported rod is susceptible to bending under side loads. Employing an external guide rail or a dedicated guided cylinder system is critical to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other standard cylinders in this size class. When integrating, match the G1/2 port, select appropriate mounting accessories like FA flanges or TC trunnions, and note that external pilot-operated check valves are required to hold loads if air pressure is lost, as the standard air cushion only decelerates the piston at stroke end.
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 SAI100X325 FAQ
At 0.5 MPa operating pressure, the SAI100X325 provides 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X325 is dimensionally interchangeable per ISO 15552. It shares standard mounting interfaces, G1/2 ports, and a 100 mm bore profile, allowing it to serve as a drop-in replacement for equivalent ISO 15552 profile cylinders.
