About the Airtac SAI63 Standard Cylinder SAI63X55
The AirTAC SAI63X55 is a double-acting ISO 15552 profile cylinder engineered for compact actuation. It generates 1559N of push force and 1402N of pull force at 0.5MPa. The 55mm stroke is optimal for short-travel clamping and lifting tasks. A standard carbon steel piston rod provides robust durability.
For high-temperature environments up to 70C, standard TPU seals perform reliably, while Viton (H) and NBR (N) options exist for specialized fluid conditions. The extruded aluminum barrel features sensor grooves on both sides, ready for CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI63 Standard Cylinder SAI63X55 Is Used
Short-Stroke Clamping
Provides reliable 1559N holding force for machining fixtures.
Package Diverting
Actuates diverter arms quickly over short 55mm distances.
Part Ejection
Ejects finished components from press lines efficiently.
Is the Airtac SAI63 Standard Cylinder SAI63X55 the Right Cylinder?
If 1559N at 0.5MPa is insufficient, step up to the 80mm bore for 2513N; if you need less force, the 50mm bore offers 982N. Because this is a 55mm stroke, side-load stress on the rod bearing is minimal. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. For dead-drop prevention, use the SAIL variant or an external rod lock. This SAI63X55 is dimensionally interchangeable with other ISO 15552 cylinders, featuring a G3/8 PT port and standard mounting accessories like FA flanges.
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.
