About the Airtac SAI63 Standard Cylinder SAI63BX145S
The AirTAC SAI63X145-S is a double-acting ISO 15552 profile cylinder offering a non-standard 145mm made-to-order stroke. It delivers a robust 1559N push force at 0.5 MPa, making it highly suitable for mid-range industrial automation tasks. The extruded aluminum barrel design omits tie rods while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsher environments. It is equipped with a magnet (-S) to seamlessly integrate with CMSE and DMSE sensor switches, utilizing the dual sensor grooves molded directly into the barrel profile.

Where the Airtac SAI63 Standard Cylinder SAI63BX145S Is Used
Mid-Tonnage Stamping
Provides 1559N of push force at 0.5 MPa for actuating small presses and stamping assemblies.
Diversion Gates
Drives heavy-duty sorting flaps on packaging lines where a 145mm travel distance is required.
Corrosive Environment Actuation
The SUS304 stainless rod handles clamping tasks in washdown or chemically exposed manufacturing zones.
Is the Airtac SAI63 Standard Cylinder SAI63BX145S the Right Cylinder?
Selecting this 63mm bore is ideal when your application requires upward of 1559N thrust at 0.5 MPa, bridging the gap between the 50mm bore (982N) and the larger 80mm bore (2513N). Because this is a non-standard 145mm stroke, expect a made-to-order lead time. The PT tapered port thread ensures a robust, leak-free pneumatic connection.
For this 145mm stroke length, side-load risks are moderate but manageable. Ensure proper rod-bearing alignment to prevent premature wear. Note that the standard variable air cushions at both ends only decelerate the piston near stroke completion; they do not lock the load. If your system loses air pressure, the rod will drift. For secure position holding without live pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead.
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 SAI63BX145S FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder generates 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
Yes, the SAI63X145-S shares the exact ISO 15552 mounting interface and dimensions, allowing it to interchange with other standard profile cylinders. It uses PT tapered G3/8 ports and supports FA, FB, LB, and TC mounting accessories.
