About the Airtac SAI160 Standard Cylinder SAI160BX850
The AirTAC SAI160X850 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial push force of 14074 N at 0.7 MPa, making it well-suited for high-mass displacement across its 850 mm stroke. This extended length is a standard catalog offering for the 160 mm bore, maintaining a maximum standard limit of 1500 mm.
This specific configuration incorporates a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh or washdown environments. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it does not have built-in magnetic fields for proximity sensing. For applications requiring position holding upon air loss, consider the SAIL pneumatic lock variant.

Where the Airtac SAI160 Standard Cylinder SAI160BX850 Is Used
Heavy Stamping
Provides the 14074 N push force at 0.7 MPa required to form thick metal sheets and actuate large press assemblies.
Automotive Welding
The SUS304 rod withstands weld-splatter and coolant washdowns, while the 850 mm stroke spans wide chassis jigs.
Bulk Material Diversion
Handles large heavy pallets or bulk aggregate gates across wide conveyor belts using its extended travel distance.
Is the Airtac SAI160 Standard Cylinder SAI160BX850 the Right Cylinder?
Selecting this 160 mm bore provides massive thrust, stepping up significantly from the 100 mm bore which offers 5497 N at 0.7 MPa. If 14074 N is excessive, dropping to the 100 mm option saves space and air consumption. At an 850 mm stroke, the extended unsupported piston rod is highly susceptible to bending under side loads. Utilizing an external linear guide or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
This model uses a G3/4 port. Because it is a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for direct retrofits. Remember that a standard double-acting cylinder will drift if air pressure is lost; use an external pilot-operated check valve if the load must be safely suspended.
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 SAI160BX850 FAQ
At 0.7 MPa operating pressure, 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, the SAI series is a genuine ISO 15552 profile cylinder. Its standardized mounting interface and envelope dimensions make it a direct replacement for other ISO 15552 profile cylinders, though you should verify your port and accessory clearances.
