About the Airtac SAI63 Standard Cylinder SAI63X175S
The AirTAC SAI63X175-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559N of push force at 0.5 MPa. Its 175mm stroke is ideal for mid-range automation tasks requiring consistent linear motion. This extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical fouling.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. Fluid ports feature PT tapered threading, ensuring robust, leak-free pneumatic connections in demanding industrial environments.

Where the Airtac SAI63 Standard Cylinder SAI63X175S Is Used
Component Clamping
Secures medium-sized machined parts during milling or drilling operations, utilizing the 1559N push force to prevent workpiece shifting.
Package Diverting
Actuates routing arms on packaging lines to sort cartons into secondary lanes, benefiting from the 175mm stroke length.
Material Ejection
Pushes stamped metal or molded plastic parts out of press dies, using the integrated magnet to confirm ejection via sensors.
Is the Airtac SAI63 Standard Cylinder SAI63X175S the Right Cylinder?
Select this 63mm bore when an application requires roughly 1559N of thrust at 0.5 MPa, bridging the gap between the 50mm bore (982N) and the 80mm bore (2513N). Because the stroke is 175mm, it falls below the 300mm threshold where heavy side-load guidance becomes critical, though external guides are always recommended for offset loads.
As a true ISO 15552 standard cylinder, it serves as a direct replacement for any matching profile cylinder with a 63mm bore, 175mm stroke, and G3/8 port. Remember that standard pneumatic cushions only decelerate the piston at end-of-stroke; if your process must hold a load vertically without continuous air pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
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 SAI63X175S FAQ
At an operating pressure of 0.5 MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
No, the standard SAI profile cylinder relies on air pressure to maintain position and will drift if pressure is lost. For fail-safe load holding, use the SAIL lock variant or an external rod lock.
