About the Airtac SAI63 Standard Cylinder SAI63BX220S
The AirTAC SAI63X220-S is a double-acting ISO 15552 profile cylinder offering a 63mm bore and 220mm stroke. It generates 1559N of push force and 1402N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks. This specific configuration includes a magnet for position sensing.
Beyond the standard spec table, this variant features a SUS304 stainless steel rod (option B) for excellent corrosion resistance in humid or washdown environments. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches for precise end-of-stroke detection.

Where the Airtac SAI63 Standard Cylinder SAI63BX220S Is Used
Automated Clamping
Provides reliable 1559N clamping force at 0.5 MPa for securing medium-sized metal or plastic components during secondary machining operations.
Package Diverting
Drives diverters and sorting gates on packaging lines, where the 220mm stroke offers sufficient travel to redirect products efficiently.
Material Handling
Actuates lifting arms and grippers on palletizing cells, leveraging the dual sensor grooves for rapid cycle feedback.
Is the Airtac SAI63 Standard Cylinder SAI63BX220S the Right Cylinder?
This 63mm bore provides a solid step up in thrust over the 50mm version, which yields 982N at 0.5 MPa, making it ideal when you need extra power without jumping to the bulkier 80mm size. Because the 220mm stroke exceeds 300mm, it sits below the threshold requiring heavy side-load management, though utilizing external guides is always recommended if handling substantial lateral loads.
For applications requiring the piston to hold its position securely without continuous air pressure, a standard SAI cylinder will drift. In those scenarios, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model mounts via standard ISO 15552 accessories like TC trunnions or LB foot brackets, utilizing a PT G3/8 port.
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 SAI63BX220S FAQ
At a standard operating pressure of 0.5 MPa, this 63mm bore cylinder provides a push force of 1559N and a pull force of 1402N. If pressure is increased to 0.7 MPa, the push force reaches 2182N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders with a 63mm bore, matching the G3/8 port and mounting dimensions.
