About the Airtac SAI63 Standard Cylinder SAI63AX475S
The AirTAC SAI63X475-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 475mm stroke. It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for medium-duty actuation over extended distances. The extruded aluminum barrel design eliminates tie rods, providing a clean exterior that resists contamination.
This specific configuration includes a magnet for proximity sensing and utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. Tapered PT ports and dual-side sensor grooves allow seamless integration with CMSE or DMSE switches, ensuring reliable position feedback in automated machinery.

Where the Airtac SAI63 Standard Cylinder SAI63AX475S Is Used
Extended Stroke Assembly
Ideal for pushing components across a 475mm gap in automated assembly lines where a 1559 N push force is sufficient for part insertion or tool actuation.
Material Diversion
Provides reliable actuation for diverter gates on conveyor systems, using the integrated magnet with CMSE sensors to confirm gate position and prevent jams.
Packaging Equipment
Suitable for operating large format packaging flaps or platens, where the SUS420J2 stainless steel rod offers dependable resistance against occasional washdowns or humid environments.
Is the Airtac SAI63 Standard Cylinder SAI63AX475S the Right Cylinder?
When selecting this model, verify that the 1559 N output at 0.5 MPa meets your load requirements; stepping down to a 50mm bore yields 982 N, while upgrading to an 80mm bore provides 2513 N. Because the 475mm stroke creates a long unsupported rod extension, applying side loads can cause bending and premature rod-bearing wear. To manage this, guide the load externally or utilize a guided cylinder to prevent mechanical binding.
This actuator is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders with identical mounting dimensions. It features a G3/8 port, an M16x1.5 rod thread, and adjustable air cushions at both ends. Note that the standard double-acting design relies on continuous air pressure to hold position; if your application requires fail-safe load holding upon pressure loss, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the cushion.
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 SAI63AX475S FAQ
At an operating pressure of 0.5 MPa, the SAI63X475-S generates a push force of 1559 N and a pull force of 1402 N. If pressure is increased to 0.7 MPa, the push force reaches 2182 N.
Yes, the SAI series is built to the ISO 15552 profile standard, making its mounting interface and center-to-center dimensions fully interchangeable with other ISO 15552 compliant cylinders of the same bore size.
