About the Airtac SAI63 Standard Cylinder SAI63AX95S
The AirTAC SAI63X95-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa and 1402 N of pull force. Its 95 mm stroke provides an optimal mid-range extension for compact automation setups. Because it is a profile cylinder, it omits external tie rods, resulting in a clean exterior that resists snagging in tight machine cells.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A), offering superior corrosion resistance compared to standard carbon steel. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE and DMSE solid-state switches housed in the barrel's dual sensor grooves. Fluid ports are PT tapered threads, ensuring robust pneumatic sealing.

Where the Airtac SAI63 Standard Cylinder SAI63AX95S Is Used
Clamping Mechanisms
Provides reliable 1559 N clamping force at 0.5 MPa for securing medium-sized metal workpieces during machining operations.
Package Diverting
The 95 mm stroke actuates diverter arms on packaging lines, pushing products smoothly at operating speeds up to 800 mm/s.
Material Ejection
Ideal for ejecting molded parts or stamped sheets from presses, utilizing the SUS420J2 rod to resist minor environmental moisture.
Is the Airtac SAI63 Standard Cylinder SAI63AX95S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm bore yields a significant thrust upgrade, jumping from 982 N to 1559 N at 0.5 MPa. If your application requires less force and faster cycling, stepping down to the 50 mm bore is advisable. For this 95 mm stroke, side-load stress on the rod bearing is minimal, so no external guide rail is strictly necessary.
As a standard double-acting cylinder, the SAI63X95-S relies on live air pressure to hold position. If your machinery experiences sudden pressure loss or valve centering, the piston will drift. For applications requiring strict position holding without constant air pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model serves as a dimensionally interchangeable direct replacement per ISO 15552 mounting interfaces.
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 SAI63AX95S FAQ
At 0.5 MPa, this double-acting cylinder provides 1559 N of push force and 1402 N of pull force. If operated at 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X95-S is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders, provided the 63 mm bore and 95 mm stroke match your requirements.
