About the Airtac SAI63 Standard Cylinder SAI63X230S
The AirTAC SAI63X230-S is a double-acting ISO 15552 profile cylinder delivering a push force of 1559 N at 0.5 MPa. Its 230 mm stroke provides the extended travel path needed for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, giving it a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for non-contact position detection. You can mount CMSE or DMSE series reed switches directly into the sensor grooves machined on both sides of the barrel. For higher temperature environments up to 70 C, the standard TPU seals handle daily duty, but Viton (H) elastomers are available if your application runs hotter.

Where the Airtac SAI63 Standard Cylinder SAI63X230S Is Used
Mid-Force Material Pushing
Ideal for shunting medium-weight workpieces or pallets along transfer lines where 1559 N of push force at 0.5 MPa is sufficient to overcome friction.
Package Diverting
The 230 mm stroke provides the exact reach needed to actuate diverter arms on packaging conveyors, while the -S magnet enables precise end-of-stroke confirmation.
Clamping and Fixturing
Provides reliable holding pressure against machined components during secondary operations, utilizing its 1402 N pull force to retract fixtures rapidly.
Is the Airtac SAI63 Standard Cylinder SAI63X230S the Right Cylinder?
Selecting this 63 mm bore over a smaller 50 mm unit gives you a significant thrust upgrade, jumping from 982 N to 1559 N at 0.5 MPa. If your application requires less force and faster cycling, stepping down to the 50 mm bore is a viable option. Because this model features a 230 mm stroke, you must account for potential rod-bearing bending under heavy side loads; utilizing an external guide rail or a guided cylinder carriage is recommended to prevent premature wear.
This SAI63X230-S configuration uses a G3/8 PT tapered port, an M16x1.5 rod thread, and adjustable air cushions at both ends (36 mm cushion length). It functions as a direct replacement for any standard ISO 15552 mounting interface. Remember that the standard adjustable cushion only decelerates the piston near the stroke ends; it does not lock the load. If your machinery loses air pressure, the rod will drift, so consider the SAIL variant with an air-released lock or an external pilot-operated check valve for fail-safe holding.
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 SAI63X230S FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 2182 N.
Yes. The SAI series is a genuine ISO 15552 profile cylinder, making its mounting dimensions a direct replacement for other standard ISO 15552 cylinders. You can reuse existing FA flanges or LB foot brackets without modifying the machine frame.
