About the Airtac SAI160 Standard Cylinder SAI160BX120
The AirTAC SAI160X120 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 14074 N of push force at 0.7 MPa, this 160 mm bore actuator is built to move massive loads across its 120 mm stroke. The extruded aluminum barrel design eliminates exposed tie rods, providing a clean exterior that resists mechanical damage in rugged environments.
This specific configuration is equipped with a highly corrosion-resistant SUS304 stainless steel piston rod (material code B) and utilizes PT tapered port threads. Because it lacks the -S magnet option, it is optimized for pure high-force mechanical drive tasks rather than position-sensing applications. For environments requiring elevated temperatures, the standard TPU seals can be swapped for Viton (H) variants to ensure thermal stability.

Where the Airtac SAI160 Standard Cylinder SAI160BX120 Is Used
Heavy Metal Stamping
Provides the robust 14074 N push force required to drive large presses and form thick-gauge steel components securely.
Automotive Assembly
Actuates large-scale robotic welding fixtures and positions heavy chassis frames with precise 120 mm travel.
Pallet Handling
Shifts fully loaded pallets or heavy industrial containers along high-capacity conveyor lines in distribution centers.
Is the Airtac SAI160 Standard Cylinder SAI160BX120 the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application demands extreme thrust that smaller bores cannot provide, such as stepping up from a 125 mm bore which only offers 8590 N at 0.7 MPa. If 120 mm of travel is excessive for your cycle time, you can drop down to a standard 100 mm stroke while retaining the same high-force footprint. The G3/4 PT ports ensure high-volume airflow to prevent starvation during rapid movements.
Keep in mind that a standard SAI160X120 will not hold a load in place if air pressure is removed or exhausted; the piston will drift under dead weight. If your machinery requires fail-safe load holding during an emergency stop or pressure loss, integrate an external pilot-operated check valve or specify the BSAI bidirectional clamp-lock variant. Furthermore, while 120 mm is a moderate stroke, always verify that your mounting accessories (such as FA flanges) can support the cylinder's substantial weight.
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 SAI160BX120 FAQ
At a standard operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 14074 N of pull force. It can reach up to 18095 N push at 0.9 MPa.
Yes, the SAI160X120 is a true ISO 15552 profile cylinder. Its standardized mounting dimensions and G3/4 port locations make it a direct replacement for other ISO 15552 profile cylinders, allowing easy upgrades or swaps without custom brackets.
