This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X470S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X470S
The AirTAC Airtac SI100 Standard Cylinder SI100X470S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 470mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X470S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X470S
The AirTAC SI100X470S is a discontinued double-acting ISO 15552 profile cylinder featuring an extruded aluminum barrel, a 470 mm stroke, and a G1/2 port. Delivering 3927 N push force at 0.5 MPa, it is replaced by the SAI100X470S. This direct successor matches the exact bore, stroke, output force, port size, and mounting interface, fitting existing fixtures perfectly.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X470S Is Used
Heavy Goods Diverting
Handles large packages on packaging lines, using the 3927 N push force to deflect heavy pallets across transfer stations.
Press Ejection
Ejects formed metal or plastic parts from machinery, where the 470 mm stroke reaches deep into work areas to clear dies.
Pallet Positioning
Stops and locates heavy pallets on roller conveyors, requiring the robust 100 mm bore to absorb significant kinetic impact.
Replacing the Airtac SI100 Standard Cylinder SI100X470S with the SAI100X470S
To replace the SI100X470S, order the SAI100X470S. Verify the ISO 15552 mounting interface, 100 mm bore, 470 mm stroke, G1/2 port (PT/G/NPT thread), and mounting accessory. The -S magnet allows SAI current AirTAC switches to replace legacy CS1-B/DS1-B units. Sizing both ways: a 125 mm bore yields 6136 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. A plain cylinder drifts on air loss; for load holding, use the SAIL lock, BSAI clamp-lock, or an external pilot check valve. With a 470 mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X470S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X470S FAQ
Yes, the SI100X470S is discontinued. The direct replacement is the SAI100X470S. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 470 mm stroke, force, G1/2 port, and mounting interface.
It features a G1/2 port. Force ratings are 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa.
