About the Airtac SAI63 Standard Cylinder SAI63X200SG
The AirTAC SAI63X200-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 200mm stroke. It delivers a robust 1559N push force at 0.5 MPa, making it well-suited for medium-duty industrial handling and clamping tasks. The extruded aluminum barrel design eliminates traditional tie-rods, providing a clean exterior that easily drops into existing ISO 15552 mounting footprints.
Equipped with a magnetic piston (-S), this model supports direct position sensing using CMSE or DMSE switches along the integrated dual-side sensor grooves. The standard carbon steel piston rod provides excellent structural strength, while adjustable air cushions at both ends ensure smooth deceleration across its 30-800 mm/s operating speed range.

Where the Airtac SAI63 Standard Cylinder SAI63X200SG Is Used
Automated Clamping
Ideal for securing heavy metal workpieces during CNC machining, utilizing its 1559N push force to hold parts rigidly against cutting forces.
Material Diverting
Provides the necessary stroke and thrust to push products between parallel conveyor lanes in high-speed sorting and packaging lines.
Press Fitting
Exerts steady, controlled pressure to seat bearings and bushings into housings without risking impact damage from pneumatic shock.
Is the Airtac SAI63 Standard Cylinder SAI63X200SG the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option doubles your thrust, stepping up from 982N to 1559N at 0.5 MPa, which is critical if your application requires moving heavier jigs without increasing cycle time. Conversely, if your load is lighter, dropping to the 50mm bore saves compressed air and physical footprint. This 200mm stroke is well within standard limits and does not require auxiliary side-load guidance, but always ensure the load is axially aligned to prevent rod-bearing wear.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold its position; if air is lost or the valve is centered, the piston will drift. For applications requiring true position holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. This model uses a G3/8 port, accepts standard PT/G threaded fittings, and mounts via accessories like FA flanges or TC trunnions.
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 SAI63X200SG FAQ
At a standard 0.5 MPa operating pressure, this 63mm bore cylinder generates 1559N of push force and 1402N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 2182N.
Yes, the SAI63X200-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing mounts like FA flanges or TC trunnions designed for other ISO 15552 profile cylinders without modifying the machine frame.
