About the Airtac SAI63 Standard Cylinder SAI63AX200S
The AirTAC SAI63X200-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 200 mm stroke provides the extended travel needed for mid-range material handling and automated clamping tasks. Designed with a standardized mounting interface, it serves as a drop-in replacement for other ISO 15552 cylinders.
This variant features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance in humid environments. Equipped with a magnetic piston (-S), it supports CMSE and DMSE sensor switches that mount directly into the dual extruded grooves on the aluminum barrel. The cylinder also includes adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI63 Standard Cylinder SAI63AX200S Is Used
Automated Clamping
Provides 1559 N of secure clamping force at 0.5 MPa for holding workpieces during machining or welding operations.
Material Diversion
Utilizes the 200 mm stroke to push products between parallel conveyor lanes in high-speed packaging lines.
Press Ejection
Delivers reliable push force to eject formed parts from press dies, with adjustable cushions absorbing stroke impact.
Is the Airtac SAI63 Standard Cylinder SAI63AX200S the Right Cylinder?
Choose this 63 mm bore when an application requires more thrust than a 50 mm bore provides, yielding 982 N at 0.5 MPa. If your system demands less force, stepping down reduces air consumption. Because this 200 mm stroke is under the 300 mm threshold, side-load stress on the rod bearing is moderate, but external guides should still be used for heavy off-center loads.
To guarantee a seamless ISO 15552 interchange, match the 63 mm bore, 200 mm stroke, and PT G3/8 port thread. Select appropriate mounting accessories like FA flanges or TC trunnions, and ensure the -S magnet option is specified if position feedback is required. Note that standard air cushions only decelerate the piston; they do not hold a load. If static holding is needed without air pressure, use the SAIL or BSAI locking variants.
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 SAI63AX200S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X200-S is dimensionally interchangeable per ISO 15552. You can swap it directly with other ISO 15552 profile cylinders by matching the 63 mm bore, 200 mm stroke, and G3/8 port.
