About the Airtac SAI63 Standard Cylinder SAI63BX300S
The AirTAC SAI63X300-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 300 mm stroke provides the extended travel needed for material handling and automated clamping tasks. Built with an extruded aluminum barrel, it omits tie-rods for a clean, modern exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. It is equipped with a magnetic piston (-S) to trigger CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel. Fluid ports feature PT tapered threads, ensuring a robust, mechanically sealed pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63BX300S Is Used
Pallet Transfer
Pushes heavy pallets laterally across conveyor lanes using its 1559 N thrust capacity, while the 300 mm stroke clears adjacent machinery.
Clamp and Hold
Secures steel workpieces in machining fixtures. The SUS304 rod withstands coolant spray, and the magnetic piston confirms clamp position to the PLC.
Carton Sorting
Actuates diverter arms in high-speed logistics lines, utilizing adjustable air cushions to decelerate the 300 mm stroke smoothly at cycle end.
Is the Airtac SAI63 Standard Cylinder SAI63BX300S the Right Cylinder?
Select this 63 mm bore when an application requires roughly 1559 N of thrust at 0.5 MPa, bridging the gap between the lighter 50 mm bore (982 N) and the heavier 80 mm bore (2513 N). The 300 mm stroke is well within the 1500 mm maximum standard for this bore size, making it a readily available choice for general automation. Because the stroke reaches 300 mm, the unsupported rod length increases; to prevent rod-bearing bending under side loads, implement an external guide rail or select a guided cylinder module.
As a standard double-acting actuator, this model relies on continuous air pressure to move and cannot hold a load if air is exhausted or a valve is centered. If your fixture requires static position holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To match existing tooling, this cylinder drops directly into any ISO 15552 mounting footprint using standard LB, FA, or TC accessories along with PT port fittings.
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 SAI63BX300S FAQ
At a 0.5 MPa operating pressure, 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 SAI63X300-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions, port locations (G3/8), and rod thread (M16x1.5) are fully interchangeable with other ISO 15552 cylinders of the same bore and stroke.
