About the Airtac SAI63 Standard Cylinder SAI63X180
The AirTAC SAI63X180 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 180mm stroke. It generates a 1559N push force at 0.5 MPa, making it well-suited for medium-duty handling and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior.
This configuration uses a standard carbon steel piston rod and PT tapered port threads. For environments requiring position detection, the barrel features integrated sensor grooves on both sides, ready to accept CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI63 Standard Cylinder SAI63X180 Is Used
Part Ejection
Provides reliable force to push machined metal components out of a CNC fixture.
Package Diverting
Actuates a routing gate to sort medium-weight packages on a packaging line.
Material Pressing
Holds composite layers together while an adhesive cures under steady pressure.
Is the Airtac SAI63 Standard Cylinder SAI63X180 the Right Cylinder?
Select this 63mm bore when a 40mm bore (628N at 0.5 MPa) is insufficient, but an 80mm bore (2513N at 0.5 MPa) would be excessive. The 180mm stroke provides ample travel for pushing parts into fixtures. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal, though external guides are recommended if heavy off-center loads are present.
This standard SAI63X180 relies on live air pressure to hold its position; it will drift if pressure is lost. For applications requiring fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. As a true ISO 15552 cylinder, it serves as a dimensionally interchangeable direct replacement for any standard 63x180 ISO 15552 actuator using G3/8 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 SAI63X180 FAQ
At 0.5 MPa, the push force is 1559N and the pull force is 1402N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 318 kgf.
Yes. The SAI63X180 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 standard cylinders of the same bore and stroke.
