About the Airtac SAI50 Standard Cylinder SAI50BX180
The AirTAC SAI50X180 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 180 mm stroke provides the extended travel needed for mid-range material handling and packaging tasks.
This configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It utilizes PT tapered port threads and lacks a standard magnet, making it ideal for basic actuation without sensor feedback requirements.

Where the Airtac SAI50 Standard Cylinder SAI50BX180 Is Used
Packaging Equipment
Drives sealing jaws and folding mechanisms with precise 180 mm travel and 982 N thrust.
Material Diverting
Actuates routing gates on conveyor lines where the SUS304 rod resists humid or washdown environments.
Clamp Fixtures
Secures workpieces during secondary machining operations without needing position sensors.
Is the Airtac SAI50 Standard Cylinder SAI50BX180 the Right Cylinder?
If your application requires less thrust, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while moving up to a 63 mm bore provides 1559 N for heavier loads. Because this 180 mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer-travel units.
For direct compatibility, this cylinder matches the ISO 15552 mounting interface dimensions, accepting standard FA or FB flanges and TC trunnion brackets. It uses a G1/4 port. Remember that standard air cushions only decelerate the piston near stroke end; they do not hold a load. If static holding is required when air pressure drops, consider 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 SAI50 Standard Cylinder SAI50BX180 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes. The SAI50X180 is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other standard profile cylinders with matching 50 mm bore and 180 mm stroke specifications.
