About the Airtac SAI63 Standard Cylinder SAI63BX180
The AirTAC SAI63X180 is a double-acting profile cylinder that strictly adheres to the ISO 15552 mounting interface, making it a direct replacement for other ISO 15552 cylinders. It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or chemically exposed environments. It uses PT tapered port threads and lacks a standard magnet, meaning it is optimized for purely mechanical operation without direct magnetic sensing.

Where the Airtac SAI63 Standard Cylinder SAI63BX180 Is Used
Mid-Force Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing heavy metal workpieces during machining or welding operations.
Material Diverting
Actuates routing gates and diverter arms on packaging lines, utilizing the 180 mm stroke to clear product flow paths efficiently.
Pressing Operations
Drives light-duty pressing and insertion tasks where the SUS304 rod offers excellent resistance to factory floor moisture and washdowns.
Is the Airtac SAI63 Standard Cylinder SAI63BX180 the Right Cylinder?
Choose this 63 mm bore over the smaller 50 mm bore (which provides 982 N push force at 0.5 MPa) when your application demands higher thrust. If your system requires less than 1000 N of force, stepping down to the 50 mm bore saves space and air consumption. Because this is a 180 mm stroke, it remains manageable for the standard rod bearing without needing an external guide.
For interchangeability, match the 63 mm bore, 180 mm stroke, G3/8 port, and your required mounting accessory (such as an LB foot or TC trunnion). Note that this standard SAI cylinder does not hold its position when air pressure is removed; if your machine requires static load holding during an air loss event, select the SAIL variant with an air-released lock or use an external rod lock.
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.
