About the Airtac SAI63 Standard Cylinder SAI63X700S
The AirTAC SAI63X700-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 700mm stroke. It generates 1559N of push force at 0.5MPa, making it suitable for substantial actuation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that matches standardized mounting dimensions.
This unit includes a magnetic piston for position detection using CMSE or DMSE series switches, which ride securely in the dual sensor grooves on both sides of the barrel. The standard carbon steel piston rod is paired with a PT tapered port thread (G3/8), ensuring robust pneumatic connections for industrial automation.

Where the Airtac SAI63 Standard Cylinder SAI63X700S Is Used
Material Transfer
Drives long-travel pallet pushers and automated conveyor diverters requiring 1559N of push force over a 700mm extension.
Vertical Lifting
Raises and lowers light packaging platforms where a 63mm bore provides the necessary thrust for vertical displacement.
Assembly Ejection
Ejects finished parts from long machining centers, utilizing the magnetic piston for end-of-stroke confirmation via DMSE sensors.
Is the Airtac SAI63 Standard Cylinder SAI63X700S the Right Cylinder?
When evaluating this 700mm stroke model, note that long unsupported rods are susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide mechanism or select a guided cylinder variant for your assembly. If your application requires less force, the adjacent 50mm bore yields 982N at 0.5MPa; for higher force, the 80mm bore provides 2513N.
This SAI63X700-S is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other standard profile cylinders. It features a G3/8 port, a 20mm rod with M16x1.5 threading, and adjustable air cushions at both ends. Remember that the cushion only decelerates the piston near stroke end; if you need to hold a load without live air pressure, use the SAIL (lock) or BSAI (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.
