About the Airtac SAI63 Standard Cylinder SAI63AX700
The AirTAC SAI63X700 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 700mm stroke. It delivers a robust push force of 1559 N at 0.5 MPa, making it highly suitable for automation tasks requiring substantial linear displacement over an extended distance.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for easy position feedback when paired with a compatible magnet-equipped variant.

Where the Airtac SAI63 Standard Cylinder SAI63AX700 Is Used
Material Handling

Assembly Automation
Actuates large fixture plates or robotic tooling arms across wide machining stations.
Logistics Sorting
Pushes heavy cartons or metal containers onto diverter tracks at high operating speeds.
Is the Airtac SAI63 Standard Cylinder SAI63AX700 the Right Cylinder?
With a 700mm stroke, this cylinder generates 1559 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 50mm bore variant offers 982 N, while moving up to the 80mm bore provides 2513 N for heavier loads. Because this stroke length is 700mm, the unsupported rod is highly susceptible to bending under side loads; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model uses a G3/8 port and is dimensionally interchangeable with other ISO 15552 cylinders. If a machine requires true load holding without constant air pressure, a standard SAI will drift; consider the SAIL variant with an air-released lock or an external pilot-operated check valve for fail-safe positioning.
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 SAI63AX700 FAQ
At a standard operating pressure of 0.5 MPa, this 63mm bore cylinder provides a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X700 is a true ISO 15552 profile cylinder. Its mounting interface dimensions, G3/8 port, and M16x1.5 rod thread allow it to serve as a drop-in replacement for other ISO 15552 standard cylinders.
