About the Airtac SAI63 Standard Cylinder SAI63AX200
The AirTAC SAI63X200 is a double-acting profile cylinder built to exact ISO 15552 dimensional standards. It features a 63mm bore and a 200mm stroke, generating 1559N of push force and 1402N of pull force at 0.5 MPa. This makes it a robust choice for medium-duty automation tasks requiring substantial linear thrust.
This model incorporates a SUS420J2 stainless steel piston rod for superior corrosion and wear resistance compared to standard carbon steel. The barrel utilizes an extruded aluminum design with integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet is specified later. Fluid supply connects via PT tapered G3/8 ports, and the unit includes adjustable air cushions at both ends to absorb impact energy.

Where the Airtac SAI63 Standard Cylinder SAI63AX200 Is Used
Automated Clamping Stations
Provides the 1559N push force required to secure heavy metal workpieces during CNC machining or welding operations.
Pallet Indexing Gates
Utilizes the 200mm stroke to extend and retract routing arms, diverting packaged goods between conveyor lines.
Vertical Lift Stops
Acts as a pneumatic stopper in material handling lifts, using its robust 63mm profile barrel to halt descending loads.
Is the Airtac SAI63 Standard Cylinder SAI63AX200 the Right Cylinder?
Selecting this 63mm bore is ideal when a 50mm bore (982N push at 0.5 MPa) lacks the necessary thrust, but an 80mm bore (2513N push) would be physically oversized and consume excess air. The 200mm stroke provides ample travel for clamping, lifting, or indexing without requiring a custom made-to-order length. Because this is a double-acting cylinder, it relies entirely on continuous air pressure to move and hold the load; if pneumatic supply is lost, the piston will drift.
For applications needing absolute position holding upon air failure, consider the SAIL variant with an air-released lock, or integrate an external pilot-operated check valve. This SAI63X200 serves as a direct dimensional drop-in replacement for any ISO 15552 profile cylinder, matching the exact 63mm mounting interface, 200mm stroke, G3/8 PT port, and standard accessory compatibility (such as 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 SAI63AX200 FAQ
At a standard operating pressure of 0.5 MPa, the SAI63X200 generates 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
Yes. The SAI63X200 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. It matches standard mounting interfaces and utilizes a G3/8 PT port.
