About the Airtac SAI63 Standard Cylinder SAI63BX180S
The AirTAC SAI63X180-S is a double-acting ISO 15552 profile cylinder built for demanding industrial tasks. It generates 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it highly effective for medium-duty actuation. The 180 mm stroke provides the precise travel needed for packaging and automated assembly tasks.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in wet or chemically exposed environments. It also features an integrated magnet (-S), allowing seamless operation with CMSE and DMSE sensor switches mounted in the dual side grooves of the extruded aluminum barrel.

Where the Airtac SAI63 Standard Cylinder SAI63BX180S Is Used
Stainless Component Handling
The SUS304 rod withstands washdown environments, making it perfect for actuating grippers in food-grade or medical parts assembly.
Packaging Line Diverters
Provides the 180 mm travel and 1559 N force needed to push cartons or reposition packaging materials reliably.
Woodworking Clamps
Holds workpieces securely during cutting or routing, using the magnet-ready barrel for end-of-stroke confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63BX180S the Right Cylinder?
Selecting this 63 mm bore cylinder is ideal when your application requires around 1559 N of thrust at 0.5 MPa but does not need the full 2182 N output (at 0.7 MPa) of the larger 80 mm bore variant. Conversely, if your layout demands a smaller footprint, the 50 mm bore offers 982 N of push force at 0.5 MPa. The PT tapered port threads ensure a robust, leak-free pneumatic connection.
Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal compared to longer units. However, remember that the standard adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load in place. If your machinery loses air pressure, the rod will drift. For vertical loads requiring true position holding without continuous air, specify the SAIL locking variant or an external pilot-operated check valve.
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.
