This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X100SH, 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 SI100X100SH
The AirTAC Airtac SI100 Standard Cylinder SI100X100SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X100SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X100SH
The AirTAC SI100X100SH is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 100mm stroke. It delivers 3927 N push force at 0.5 MPa via a G1/2 port. The direct replacement is the SAI100X100SH, matching the exact bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SI unit includes a high-temp Viton H seal (0-150 C) and a piston magnet for 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 SI100X100SH Is Used
Heavy Press Clamping
Generates 3927 N of push force at 0.5 MPa to secure heavy metal workpieces in machining and press fixtures.
Pallet Diversion
Provides robust actuation to push loaded pallets off a main conveyor line using its 100mm stroke.
Replacing the Airtac SI100 Standard Cylinder SI100X100SH with the SAI100X100SH
To replace this SI cylinder, order the SAI100X100SH. Confirm the ISO 15552 mounting interface, 100mm bore, 100mm stroke, G1/2 port, and the -S magnet for current AirTAC switches. For sizing down, an 80mm bore yields 2513 N push at 0.5 MPa; sizing up to 125mm gives 6136 N. Note: a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X100SH
- ✓ 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 SI100X100SH FAQ
Yes, the SI100X100SH is discontinued. The direct replacement is the SAI100X100SH. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 100mm stroke, output force, G1/2 port and mounting accessories.
The bore is 100mm with a G1/2 air port. Theoretical forces 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 maximum force of 801 kgf at 1.0 MPa.
