About the Airtac SAI63 Standard Cylinder SAI63BX95
The AirTAC SAI63X95 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 95 mm stroke provides a compact yet highly effective extension length for mid-range automation tasks. Because it adheres strictly to ISO 15552 dimensional standards, this tie-rod-less extruded aluminum cylinder serves as a direct replacement for comparable ISO interfaces.
This specific configuration utilizes a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance compared to standard carbon steel. It features PT tapered port threads and lacks a built-in magnet. For high-temperature environments up to +70 C, the standard TPU seals can be swapped for Viton (code H) to ensure continuous reliable operation.

Where the Airtac SAI63 Standard Cylinder SAI63BX95 Is Used
Clamping Mechanisms
Provides robust 1559 N holding force at 0.5 MPa for securing heavy metal workpieces during machining or welding operations.
Product Diverting
The 95 mm stroke actuates diverter arms swiftly on packaging lines, moving cartons between parallel conveyor belts.
Press Operations
Exerts steady downward pressure for light-duty assembly presses, inserting pins or bearings into housings.
Is the Airtac SAI63 Standard Cylinder SAI63BX95 the Right Cylinder?
Selecting this 63 mm bore is ideal when your application requires roughly 1559 N of thrust at 0.5 MPa, bridging the gap between the 50 mm bore (982 N) and the larger 80 mm bore (2513 N). The 95 mm stroke is well-suited for short to medium transfers. If your mechanism must maintain its position without continuous live air pressure, note that the standard adjustable air cushion only decelerates the piston at stroke ends and does not act as a brake; you should specify the SAIL variant for pneumatic locking or the BSAI for clamp-locking.
To achieve a true ISO 15552 replacement match, ensure your mounting accessory (such as an LB foot or TC trunnion) aligns with the standardized dimensions. The G3/8 ports should be paired with appropriately sized PT fittings to prevent flow restrictions.
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 SAI63BX95 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 pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X95 is dimensionally interchangeable per ISO 15552. It shares the same mounting interface and profile barrel dimensions as other standard ISO 15552 cylinders, allowing for a direct replacement.
