About the Airtac SAI63 Standard Cylinder SAI63X220
The AirTAC SAI63X220 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 220mm stroke. It provides a robust push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it a highly reliable choice for medium-duty industrial motion tasks.
This model features a standard carbon steel piston rod and utilizes a PT tapered port thread for secure pneumatic connections. Because it lacks the -S magnet option, it does not integrate position sensors; for applications requiring direct replacements, its mounting interface matches standard ISO 15552 dimensions exactly.

Where the Airtac SAI63 Standard Cylinder SAI63X220 Is Used
Automated Assembly Press
Provides the precise 1559 N push force at 0.5 MPa needed to seat bearings and pins in automated machining lines.
Package Diverting Arm
The 220mm stroke actuates a diverter gate smoothly on high-speed material handling conveyors.
Pneumatic Clamping Fixture
Secures heavy metal workpieces during CNC machining, utilizing the robust carbon steel rod for high rigidity.
Is the Airtac SAI63 Standard Cylinder SAI63X220 the Right Cylinder?
Selecting this 63mm bore is ideal when a 50mm bore's 982 N push force at 0.5 MPa is insufficient, but an 80mm bore's 2513 N would be excessive overkill. The 220mm stroke offers extended travel for pushing or lifting tasks. If your machinery requires position feedback, you must step up to an SAI63X220-S variant equipped with a magnet for CMSE or DMSE switches.
Because this stroke exceeds 300 mm? No, 220 mm is under that threshold, so standard rod bearing support is adequate without external guides. However, remember that a standard SAI cylinder will drift if air pressure is lost. If your application requires true load holding during an air failure, consider the SAIL (lock) or BSAI (clamp-lock) variant instead.
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.
