About the Airtac SAI160 Standard Cylinder SAI160AX400S
The AirTAC SAI160X400-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations. Delivering a substantial 14074 N of push force at 0.7 MPa, this 160 mm bore actuator is built to move serious loads across its 400 mm stroke. The extruded aluminum barrel design omits traditional tie-rods, providing a clean exterior that aligns perfectly with standardized ISO 15552 mounting dimensions.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion and wear resistance in harsh environments. It is equipped with a magnetic piston (-S) for seamless integration with CMSE or DMSE sensor switches, which seat neatly into the dual sensor grooves machined into the barrel profile. Fluid ports utilize a PT tapered thread standard to ensure robust, leak-free pneumatic connections.

Where the Airtac SAI160 Standard Cylinder SAI160AX400S Is Used
Heavy Metal Stamping
Provides the high thrust and 400mm reach required to actuate large presses and form heavy-gauge metal components securely.
Automotive Body Welding
Handles robust clamping force for positioning chassis frames and holding large sub-assemblies during automated welding cycles.
Bulk Material Diverting
Drives heavy-duty diverters and sorting gates on high-capacity production lines where substantial mass demands reliable 14074N force.
Is the Airtac SAI160 Standard Cylinder SAI160AX400S the Right Cylinder?
When optimizing your setup, stepping down to a 125 mm bore drops the 0.5 MPa push force to 6136 N, whereas moving up to a 200 mm bore increases it to 15708 N. Ensure your rod thread matches your mechanical coupling; this 160 mm bore utilizes an M36x2 thread. The integrated adjustable air cushions at both stroke ends are designed to decelerate the piston smoothly, minimizing impact shock.
Because this model features a 400 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a fully guided cylinder for any applications involving off-center loads. Furthermore, a standard double-acting cylinder will drift and drop its payload if air pressure is lost or the control valve is centered; to safely hold a vertical load without live pressure, specify the SAIL locking variant or a BSAI bidirectional clamp-lock actuator.
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 SAI160 Standard Cylinder SAI160AX400S FAQ
At a standard operating pressure of 0.7 MPa, this 160mm 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, the SAI160X400-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing ISO 15552 mounting setups, utilizing accessories like FA flanges or TC trunnions without modifying the machine frame.
