About the Airtac SAI100 Standard Air Cylinder SAI100X475S
The AirTAC SAI100X475-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The 475 mm stroke handles extended travel requirements for large-scale material handling. This unit includes a magnetic piston for proximity sensing.
Built with a standard carbon steel piston rod and tapered PT threads, it integrates seamlessly into existing pneumatic setups. The extruded aluminum barrel features sensor grooves on both sides, allowing direct mounting of CMSE or DMSE reed switches without extra brackets. Adjustable air cushions at both ends ensure smooth deceleration of dynamic loads.

Where the Airtac SAI100 Standard Air Cylinder SAI100X475S Is Used
Heavy Material Handling
Ideal for driving large pneumatic presses or lifting heavy metal sheets on automotive assembly lines.
Extended Transfer Pushing
The 475 mm stroke provides the long reach needed to index heavy pallets or products between conveyor belts.
Large Fixture Actuation
Moves heavy machining fixtures into position under CNC centers, utilizing the 3927 N push force at 0.5 MPa.
Is the Airtac SAI100 Standard Air Cylinder SAI100X475S the Right Cylinder?
This 100 mm bore is a significant step up from the 80 mm version, which offers 2513 N of push force at 0.5 MPa. Choose this larger cylinder when your application demands higher thrust to move heavier fixtures or overcome substantial friction. For lower force needs, stepping down reduces air consumption and physical footprint.
With a 475 mm stroke, the unsupported rod length is substantial. Side loads can bend the rod and prematurely wear the guide bearing. Implement an external linear guide or use a guided cylinder to prevent rod deflection. Note that a standard SAI does not hold loads when air pressure is removed; for position holding, consider the SAIL or BSAI locking variants. Replacement is straightforward: match the 100 mm bore, 475 mm stroke, G1/2 port, and appropriate mounting accessory.
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 SAI100X475S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552. You can drop it into existing machinery by matching the 100 mm bore, 475 mm stroke, and G1/2 port size.
