About the Airtac SAI100 Standard Air Cylinder SAI100AX475S
The AirTAC SAI100X475-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. It provides a robust push force of 3927 N at 0.5 MPa and a pull force of 3681 N. The 475 mm stroke is ideal for automated machinery requiring substantial linear travel over long distances.
This variant features a SUS420J2 stainless steel piston rod (option A) for superior corrosion resistance in humid environments. It includes a built-in magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which seat securely into the dual extruded grooves on the aluminum barrel. The fluid porting utilizes PT tapered threads, ensuring tight, leak-free pneumatic connections.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX475S Is Used
Automotive Assembly
Drives heavy stamping presses and component positioning arms over long linear travel distances.
Pallet Handling
Actuates large pallet stops and heavy-duty routing gates in high-throughput logistics centers.
Plastic Molding
Operates heavy mold ejectors and clamping fixtures requiring high pulling force and reliable magnetic sensing.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX475S the Right Cylinder?
If your application requires less thrust, stepping down to the 80 mm bore yields 2513 N of push force at 0.5 MPa. However, for loads demanding up to 5497 N at 0.7 MPa, this 100 mm bore is the optimal choice. The PT port thread type and G3/8 port size must be matched precisely during plumbing installation.
Because the 475 mm stroke creates a long unsupported rod extension, side loads can cause severe bending stresses and premature rod-bearing wear. To manage this, implement an external guide rail or use a fully guided cylinder to prevent rod deflection. Note that a standard SAI cylinder relies on live air pressure to hold its load; if pneumatic supply is lost, the piston will drift. For fail-safe load holding without air, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant.
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 SAI100 Standard Air Cylinder SAI100AX475S FAQ
At 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
No, a standard SAI cylinder will drift or drop if air pressure is lost or exhausted. For fail-safe position holding, you should use the SAIL (with air-released lock) or BSAI (bidirectional clamp-lock) variants instead.
