About the Airtac SAI63 Standard Cylinder SAI63BX230S
The AirTAC SAI63X230-S is a double-acting ISO 15552 profile cylinder engineered with a 63mm bore and a 230mm stroke. Operating at 0.5 MPa, it provides a push force of 1559 N and a pull force of 1402 N, making it a robust choice for mid-range industrial automation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes a SUS304 stainless steel piston rod (option B), offering superior corrosion resistance for humid or chemically exposed environments. Equipped with a magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches housed in the dual side grooves. Ports feature PT threading, and adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63BX230S Is Used
Material Handling
Ideal for pushing or diverting heavier pallets and packages on conveyor lines where the 1559 N force easily overcomes friction and inertia.
Machine Clamping
Provides reliable clamping pressure for machining fixtures, utilizing the 230mm stroke to accommodate varying part widths securely.
Packaging Equipment
Drives sealing and forming mechanisms in automated packaging machinery, benefiting from the adjustable cushions to protect delicate components.
Is the Airtac SAI63 Standard Cylinder SAI63BX230S the Right Cylinder?
When upgrading from a 50mm bore unit, note that the 50mm variant yields 982 N of push force at 0.5 MPa; this 63mm model steps up to 1559 N, providing the necessary thrust for heavier fixtures. If your application requires even greater power, the 80mm bore version reaches 2513 N. For this 230mm stroke, standard mounting accessories include FA/FB flanges, LB foot brackets, or TC trunnion joints, all conforming to ISO 15552 interface dimensions for direct interchangeability.
Because this stroke is 230mm, the unsupported rod length is considerable; always verify that your load is guided to prevent rod-bearing bending and premature seal wear. Additionally, a standard SAI cylinder relies on continuous air pressure to hold position. If your sequence loses pressure or the valve centers, the load will drift. For fail-safe position holding, consider the SAIL variant with an air-released lock, or integrate an external pilot-operated check valve.
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 SAI63BX230S FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. At the maximum 1.0 MPa, the theoretical force reaches 318 kgf.
Yes, the SAI63X230-S is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders by matching the 63mm bore, 230mm stroke, and PT G3/8 port size.
