About the Airtac SAI100 Standard Air Cylinder SAI100X325S
The AirTAC SAI100X325-S is a double-acting ISO 15552 profile cylinder offering a 325mm stroke with a 100mm bore. It delivers a robust 3927N push force at 0.5MPa, scaling up to 5497N at 0.7MPa. This specific stroke length is well-suited for mid-range automation tasks requiring substantial linear displacement. The extruded aluminum barrel design omits tie rods, providing a clean exterior that matches standard ISO 15552 mounting dimensions for direct interchangeability.
This variant includes a standard magnet (-S) for use with CMSE and DMSE series sensor switches, which seat neatly into the dual sensor grooves machined into both sides of the barrel. The piston rod is constructed from carbon steel for high tensile strength, and the body porting utilizes a PT tapered thread to ensure a reliable, sealed pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X325S Is Used
Heavy-Duty Pressing
Ideal for applying consistent 3927N clamping or pressing forces at 0.5MPa on heavy metal or composite components during machining operations.
Pallet Diversion
The 325mm stroke provides the exact reach needed to push heavy pallets or product totes from a main conveyor line onto a secondary packaging branch.
Automated Lift Gates
Provides the necessary 5497N thrust at 0.7MPa to raise and lower heavy automated safety gates or machine access doors over a 325mm travel distance.
Is the Airtac SAI100 Standard Air Cylinder SAI100X325S the Right Cylinder?
When sizing this actuator, stepping down to an 80mm bore yields 2513N of push force at 0.5MPa, whereas moving up is not an option within this frame size. The 100mm bore is the optimal choice when your application demands roughly 3927N to 5497N of force. Because this model features a 325mm stroke, the unsupported rod length is significant; side loads can cause rod-bearing bending and premature wear. For applications involving lateral forces, utilize an external guide rail or select a guided cylinder to prevent rod deflection.
The adjustable air cushions at both ends decelerate the piston to prevent impact damage, but they do not lock the load. If your machinery must hold a position vertically or resist gravity during a complete loss of air pressure, this standard cylinder will drift. In such cases, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. Replacement is straightforward: match the 100mm bore, 325mm stroke, G1/2 port, and ISO mounting accessories like FA flanges or TC trunnions.

- ✓ 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 SAI100X325S FAQ
At 0.5MPa, the push force is 3927N and the pull force is 3681N. If you increase the operating pressure to 0.7MPa, the push force rises to 5497N.
Yes, the SAI100X325-S is dimensionally interchangeable per ISO 15552. You can directly swap it with other ISO 15552 profile cylinders by matching the 100mm bore, 325mm stroke, and G1/2 port.
