This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X150SH, 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 SI100X150SH
The AirTAC Airtac SI100 Standard Cylinder SI100X150SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X150SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X150SH
The AirTAC SI100X150SH is a discontinued double-acting ISO 15552 profile cylinder. Delivering 3927 N push force at 0.5 MPa through a 100 mm bore, it is replaced by the SAI100X150SH. This direct successor retains the same G1/2 port, M20x1.5 rod thread, and 150 mm stroke. The -S suffix means it has a piston magnet for CS1-B/DS1-B switches, while the -H denotes a Viton seal rated for 0-150 C.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds BSAI clamp-lock and SAIF built-in valve variants absent in the SI line.

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 SI100X150SH Is Used
Heavy Press Operations
Applies 3927 N of thrust at 0.5 MPa for forming, stamping, and pressing heavy components securely in automated lines.
Pallet Diversion
Handles robust 150 mm stroke movements to redirect or stop heavy pallets using the ISO 15552 mounting interface.
High-Temp Ejection
Utilizes the Viton H seal to reliably eject parts in heated environments up to 150 C without degrading.
Replacing the Airtac SI100 Standard Cylinder SI100X150SH with the SAI100X150SH
To replace the SI100X150SH, order the SAI100X150SH. It drops into existing fixtures via the identical ISO 15552 mounting interface, matching the 100 mm bore, 150 mm stroke, G1/2 port, and 36 mm cushions. Keep the -S for the magnet and -H for the Viton high-temperature seal. If you need more force, the 125 mm bore offers 6136 N at 0.5 MPa; if less is required, the 80 mm bore provides 2513 N. Remember, a standard cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or switch to the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X150SH
- ✓ 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 SI100X150SH FAQ
Yes, the SI100X150SH is discontinued. The direct replacement is the SAI100X150SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 150 mm stroke, G1/2 port, and mounting interface.
The G1/2 port bore delivers a push of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa push is 5497 N, and 7068 N at 0.9 MPa. The theoretical max force is 801 kgf at 1.0 MPa.
