About the Airtac SAI160 Standard Cylinder SAI160AX425S
The AirTAC SAI160X425-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 14074 N of push force at 0.7 MPa, this 160 mm bore actuator handles substantial loads. The 425 mm stroke is ideal for processes requiring long, powerful linear travel. As an extruded aluminum profile barrel design, it drops seamlessly into existing ISO 15552 mounting interfaces.
This specific configuration includes a -S magnet for direct compatibility with CMSE and DMSE sensor switches, which seat neatly into the dual side grooves. It is built with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The cylinder operates at speeds of 30-500 mm/s and utilizes PT tapered port threads.

Where the Airtac SAI160 Standard Cylinder SAI160AX425S Is Used
Heavy Stamping
Provides the 14074 N push force required to actuate large mechanical presses and form thick metal components.
Injection Molding
Utilizes the 425 mm stroke to extract deep-cavity molded parts from heavy industrial injection machinery.
Pallet Handling
Drives robust lifting and positioning mechanisms for fully loaded pallets in high-capacity automated distribution hubs.
Is the Airtac SAI160 Standard Cylinder SAI160AX425S the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when 100 mm cylinders (providing 5497 N push at 0.7 MPa) lack the thrust for your heavy payload, but a 200 mm bore is physically too large. The 425 mm stroke provides extensive reach, but strokes of this length demand careful attention to mechanical stability.
Because the 425 mm stroke exceeds the 300 mm threshold, the unsupported rod is highly susceptible to bending under side loads. You must use external guide rails or a guided cylinder carriage to prevent rod-bearing damage. Note that the adjustable air cushions at both ends only decelerate the piston; they do not hold the load. If pressure drops, the rod will drift. For dead-load holding, integrate an external pilot-operated check valve or specify an SAIL or BSAI lock variant. This unit is fully interchangeable with other ISO 15552 cylinders via standard FA, FB, CA, CB, or TC mounts.

- ✓ 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 SAI160 Standard Cylinder SAI160AX425S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes. It is a true ISO 15552 profile cylinder, making its mounting dimensions and interface fully interchangeable with other ISO 15552 compliant actuators. You can swap it using standard TC, CA, or FA mounting accessories.
