This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX60S, 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 SI100AX60S
The AirTAC Airtac SI100 Standard Cylinder SI100AX60S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 60mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX60S
The AirTAC SI100AX60S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore, 60mm stroke, and SUS420J2 stainless steel rod. Delivering 3927N push at 0.5MPa, it is replaced by the SAI100AX60S. This direct upgrade keeps the G1/2 port, M20x1.5 thread, and 36mm cushions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. The SAI family adds SAIL, SAIF, and BSAI lock variants. Your -S magnet works with CS1-B/DS1-B switches.

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 SI100AX60S Is Used
Heavy Pressing
Applies 3927N of push force at 0.5MPa for seating heavy bearings or forming components on automated lines.
Pallet Handling
Drives robust 60mm stroke lifts or stops for heavy pallets, utilizing the 100mm bore's 200kg vertical lift capacity.
Stainless Clamping
Uses the SUS420J2 rod to securely clamp large workpieces in humid or washdown manufacturing environments.
Replacing the Airtac SI100 Standard Cylinder SI100AX60S with the SAI100AX60S
To replace the SI100AX60S, order SAI100AX60S. Verify the ISO 15552 mounting interface, 60mm stroke, G1/2 port, and SUS420J2 rod. The -S magnet supports CS1-B/DS1-B sensors. Push is 3927N at 0.5MPa; if undersized, the 125mm bore offers 6136N. Air cushions only decelerate; for load holding on air loss, use SAIL or BSAI lock variants. At 60mm stroke, side-load risks are minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX60S
- ✓ 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 SI100AX60S FAQ
Yes, the SI100AX60S is discontinued. The direct replacement is the SAI100AX60S. It shares the same ISO 15552 mounting interface, 100mm bore, 60mm stroke, G1/2 port, and output force, fitting existing fixtures perfectly.
It features a G1/2 air port. Force ratings are: 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a maximum theoretical force of 801kgf at 1.0MPa.
