About the Airtac SAI63 Standard Cylinder SAI63BX175
The AirTAC SAI63X175 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 175mm stroke. It generates 1559N of push force at 0.5 MPa, making it highly capable for mid-range industrial motion tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and maintenance.
This specific configuration is built with a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in wet or chemically exposed environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning it is optimized purely for pneumatic actuation without internal sensing unless externally specified.

Where the Airtac SAI63 Standard Cylinder SAI63BX175 Is Used
Automated Clamping
Provides 1559N of push force at 0.5 MPa for securing heavy metal components during CNC machining or welding processes.
Material Diverting
Actuates heavy-duty diverter arms on packaging lines where the 175mm stroke provides the necessary reach to redirect products.
Press Operations
Drives small pneumatic presses for light stamping, riveting, or assembly tasks requiring consistent mid-level force.
Is the Airtac SAI63 Standard Cylinder SAI63BX175 the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option yields a significant force jump, moving from 982N to 1559N at 0.5 MPa. If your application requires less thrust, stepping down to the 50mm bore saves space and air consumption. Because this is a double-acting cylinder, it relies entirely on continuous air pressure to maintain position; if air is removed, the piston will drift. For loads requiring static holding without live pressure, consider the SAIL variant with an air-released lock.
This model provides direct dimensional interchangeability with other ISO 15552 cylinders. To match a replacement, ensure the 63mm bore, 175mm stroke, G3/8 PT port, and desired mounting accessories (like TC trunnion or FA flange) align with your existing fixture.
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 SAI63 Standard Cylinder SAI63BX175 FAQ
