About the Airtac SAI63 Standard Cylinder SAI63AX170S
The AirTAC SAI63X170-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 170mm stroke. It generates 1559N of push force and 1402N of pull force at 0.5MPa, making it a robust choice for medium-duty industrial motion. The extruded aluminum barrel omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a magnet (-S) for use with CMSE and DMSE series sensor switches, which ride securely in the dual side grooves of the barrel. Furthermore, the piston rod is constructed from SUS420J2 stainless steel (material code A), offering enhanced resistance to corrosion and moisture compared to standard carbon steel rods. Ports feature PT tapered threading for reliable pneumatic sealing.

Where the Airtac SAI63 Standard Cylinder SAI63AX170S Is Used
Package Diversion
Provides the 1559N push force needed to reliably divert heavy packages on high-speed sorting conveyors at 0.5MPa.
Clamping Fixtures
Secures metal workpieces during machining operations, utilizing the SUS420J2 stainless rod to resist coolant exposure.
Material Ejection
Drives molded or stamped parts out of press dies, using the integrated magnet to trigger CMSE position switches for cycle confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63AX170S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your thrust from 982N to 1559N at 0.5MPa, while stepping down from an 80mm bore saves space without a drastic force loss. The 170mm stroke is well within the 1500mm standard maximum, meaning no made-to-order lead times are required.
For applications requiring the load to remain securely in place during a loss of air pressure, note that the adjustable air cushions at both ends only decelerate the piston near stroke end and do not function as a locking mechanism. To hold a load safely without live pressure, consider the SAIL variant with an air-released lock, the BSAI bidirectional clamp-lock, or an external rod lock. To replace an existing unit, match the 63mm bore, 170mm stroke, G3/8 port, and your desired mounting accessory such as an FA flange or TC trunnion.
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 SAI63AX170S FAQ
At 0.5MPa operating pressure, the SAI63X170-S generates 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
Yes, the SAI63X170-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting interfaces by matching the 63mm bore, 170mm stroke, and G3/8 port size.
