About the Airtac SAI63 Standard Cylinder SAI63X475S
The AirTAC SAI63X475-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 475 mm stroke is well suited for mid-range material handling and automated routing tasks. The extruded aluminum barrel omits traditional tie-rods, providing a clean exterior that simplifies cleaning and sensor placement.
Equipped with a magnet (-S), this unit operates seamlessly with CMSE and DMSE reed switches housed in the dual lateral sensor grooves. The standard carbon steel piston rod offers robust durability for general industrial environments, while adjustable air cushions at both ends absorb end-of-stroke kinetic energy to protect mechanical components.

Where the Airtac SAI63 Standard Cylinder SAI63X475S Is Used
Package Diverting
Provides the 1559 N push force needed to route heavy cartons across transverse conveyor belts during automated sortation.
Press Ejection
Uses the 475 mm stroke to safely extract finished parts from deep stamping dies without interfering with the upper tooling.
Pallet Positioning
Shifts empty pallets into loading stations, utilizing the dual sensor grooves to confirm full extension in busy logistics cells.
Is the Airtac SAI63 Standard Cylinder SAI63X475S the Right Cylinder?
Selecting this 63 mm bore over a smaller 50 mm option upgrades your push force from 982 N to 1559 N at 0.5 MPa, preventing stalling under heavier payloads. Conversely, if your application only requires 982 N, stepping down to the 50 mm bore saves physical envelope and air consumption. Because this model features a 475 mm stroke, the extended rod is susceptible to bending under side loads; utilizing external guide rails or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, the SAI63X475-S serves as a drop-in replacement for any standard cylinder matching these interface dimensions, utilizing its G3/8 PT ports and standard mounting accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston and do not hold a load; if pressure is lost, the rod will drift. For dead-load holding, consider the SAIL variant with an air-released lock.
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 SAI63X475S FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If operated at 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X475-S is dimensionally interchangeable per ISO 15552. You can swap it directly with other ISO 15552 profile cylinders that share the same 63 mm bore, 475 mm stroke, and G3/8 port interface.
