About the Airtac SAI63 Standard Cylinder SAI63AX180S
The AirTAC SAI63X180-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore unit is built to handle demanding industrial motion control. The 180mm stroke strikes an effective balance for mid-range extension tasks.
This configuration includes a magnetic piston (-S) for use with CMSE or DMSE position sensors. It features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

Where the Airtac SAI63 Standard Cylinder SAI63AX180S Is Used
Automated Clamping
Provides robust 1559 N clamping force at 0.5 MPa for securing heavy metal components during machining or welding processes.
Material Diverting
Actuates diverting arms or gating mechanisms on medium-duty package handling lines with reliable 180mm extension.
Press Ejection
Ejects finished parts from press beds, utilizing the SUS420J2 stainless rod to withstand occasional impact and environmental exposure.
Is the Airtac SAI63 Standard Cylinder SAI63AX180S the Right Cylinder?
Choose this 63mm bore when a 50mm cylinder lacks sufficient thrust, as the 50mm bore provides only 982 N at 0.5 MPa. If your application requires less force and faster cycling, stepping down is ideal. For this 180mm stroke, side-load stress on the rod bearing is moderate, but using a guided cylinder or external rails is recommended if heavy off-center loads are present.
Because it is a double-acting pneumatic cylinder, it will not hold a load if air pressure is lost or the valve is centered. If your application requires static position holding without live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model serves as a drop-in replacement for any ISO 15552 cylinder with matching 63mm bore, 180mm stroke, G3/8 PT ports, and standard mounting accessories.
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 SAI63AX180S FAQ
At an operating pressure of 0.5 MPa, this 63mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X180-S is dimensionally interchangeable per ISO 15552. It shares the same 63mm bore, 180mm stroke, and mounting interface as other standard profile cylinders, allowing for a direct drop-in replacement.
