About the Airtac SAI160 Standard Cylinder SAI160BX550
The AirTAC SAI160X550 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion tasks. Delivering a robust 14074 N of push force at 0.7 MPa, this 160 mm bore unit is built to move substantial masses across a 550 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting accessory installation.
This specific configuration features a SUS304 stainless steel piston rod (material code B), ensuring superior corrosion resistance in harsh or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning external reed or solid-state sensors like the CMSE series cannot be mounted unless a -S variant is specified. For operations requiring bidirectional clamping without continuous air pressure, the related BSAI clamp-lock series is a superior alternative.

Where the Airtac SAI160 Standard Cylinder SAI160BX550 Is Used
Heavy Stamping
Provides the 14074 N push force at 0.7 MPa required to form thick metal plates and operate large press dies over a 550 mm travel distance.
Automotive Assembly
Actuates large robotic welding fixtures or positions heavy chassis components, utilizing the SUS304 rod to resist coolant and oil exposure.
Pallet Diversion
Shifts fully loaded pallets weighing hundreds of kilograms across heavy-duty transfer lines using ISO 15552 compliant mounting interfaces.
Is the Airtac SAI160 Standard Cylinder SAI160BX550 the Right Cylinder?
Selecting this 160 mm bore makes sense when the 10053 N push force at 0.5 MPa from a 125 mm bore is insufficient for your load requirements, yet you want to avoid jumping to the massive 15708 N output of a 200 mm bore. The 550 mm stroke falls well within the 1500 mm maximum standard limit for this bore size, keeping it a readily available configuration.
Because this stroke length is 550 mm, the unsupported rod extension is significant. Long strokes amplify side-load forces on the rod bearing, which can cause premature wear or bending. Implement an external linear guide or select a guided cylinder to prevent rod deflection. Furthermore, a standard SAI cylinder will drift if air pressure is lost; if your application demands fail-safe load holding, specify an external pilot-operated check valve or switch to the SAIL locking variant.
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 SAI160BX550 FAQ
At a standard operating pressure of 0.7 MPa, the SAI160X550 generates 14074 N of push force and 9425 N of pull force. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes, the SAI160X550 is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders, matching the standard mounting dimensions and G3/4 port size.
