About the Airtac SAI63 Standard Cylinder SAI63X220S
The AirTAC SAI63X220-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 220mm stroke. It generates 1559N of push force at 0.5 MPa, making it well-suited for medium-duty industrial handling tasks. The extruded aluminum barrel design omits tie rods while maintaining strict dimensional interchangeability with other ISO 15552 standard cylinders.
This specific configuration includes a piston magnet for direct compatibility with CMSE and DMSE series reed switches, which mount seamlessly into the dual sensor grooves machined on both sides of the barrel. The standard carbon steel piston rod provides robust performance, and the tapered PT thread port ensures a tight, reliable pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X220S Is Used
Automated Clamping
Holds metal workpieces securely during machining operations, utilizing the 1559N push force to resist cutting loads.
Package Diverting
Actuates routing gates on packaging lines, using the 220mm stroke to clear product profiles efficiently.
Material Ejection
Pushes finished parts out of press dies, relying on the adjustable end cushions to soften the final impact.
Is the Airtac SAI63 Standard Cylinder SAI63X220S the Right Cylinder?
Providing 1559N of thrust at 0.5 MPa, this 63mm bore offers a solid middle ground between the 50mm bore (982N) and the larger 80mm bore (2513N). For applications requiring less force and faster cycling, stepping down to the 50mm option is ideal, whereas heavy material handling dictates moving up to the 80mm variant.
At a 220mm stroke, the unsupported rod length is significant; side loads can cause rod-bearing bending, so utilizing an external guide rail or a fully guided cylinder is recommended to prevent premature wear. If your machinery requires the load to stay fixed when air pressure is removed, remember that the standard adjustable air cushions only decelerate the piston at stroke end and do not act as a lock—consider the SAIL or BSAI locking variants for fail-safe holding. This unit uses a G3/8 port, an M16x1.5 rod thread, and pairs with standard mounting accessories like LB, FA, or TC.
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.
