About the Airtac SAI63 Standard Cylinder SAI63BX170S
The AirTAC SAI63X170-S is a double-acting profile cylinder built to ISO 15552 dimensional standards, ensuring direct compatibility with equivalent ISO interfaces. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore unit is engineered for robust industrial actuation.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior moisture and corrosion resistance. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE series switches housed within the barrel's dual sensor grooves.

Where the Airtac SAI63 Standard Cylinder SAI63BX170S Is Used
Medium Payload Handling
Ideal for lifting and transferring 150kg workpieces on automated machining centers, utilizing its 1559N push force at 0.5 MPa.
Packaging Line Diverters
The 170mm stroke provides the exact reach needed for actuating sorting gates and pusher arms on high-speed packaging conveyors.
Welding Clamp Arms
The SUS304 stainless steel rod offers excellent resistance against weld spatter and shop floor moisture in robotic welding cells.
Is the Airtac SAI63 Standard Cylinder SAI63BX170S the Right Cylinder?
Providing 1559 N at 0.5 MPa, this bore sits comfortably between the 50mm (982 N) and 80mm (2513 N) options, making it a solid middle-ground choice for medium payload automation. If your application requires less force, stepping down to a 50mm bore saves space; if you need to move heavier jigs, the 80mm bore is the next logical step up.
At a 170mm stroke, side-loading risks are moderate but manageable. Ensure your mounting setup—whether using an FA flange or LB foot bracket—aligns perfectly with the PT ported body to prevent premature rod bearing wear. Note that the adjustable air cushions only decelerate the piston near the end of travel; they do not hold a load in place. If pressure drops, the rod will drift, so specify a SAIL or BSAI variant if fail-safe locking is required.
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 SAI63BX170S FAQ
At a standard operating pressure of 0.5 MPa, the SAI63X170-S 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 SAI63X170-S is dimensionally interchangeable per ISO 15552 standards, meaning it shares identical mounting footprint and pin dimensions with other ISO 15552 profile cylinders, allowing for seamless direct replacement.
