This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X100H, 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 SI100X100H
The AirTAC SI100 Standard Cylinder SI100X100H 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 SAI100X100H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X100H
The AirTAC SI100X100H 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 SAI100X100H, matching the exact ISO 15552 mounting interface, bore, stroke, force, and port size. This SKU uses a Viton H seal for 0-150 C high-temperature environments, but lacks a magnet so it cannot accept position sensors.
Upgrading to the SAI100X100H retains all ratings but adds an upgraded piston seal featuring two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the legacy SI line.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X100H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X100H Is Used
High-Temp Pressing
Applies 3927 N of force at 0.5 MPa for clamping assemblies in hot environments up to 150 C using the Viton H seal.
Heavy Material Diversion
Actuates large gauge diverters or gating mechanisms on high-capacity production lines requiring a 100mm bore.
Replacing the Airtac SI100 Standard Cylinder SI100X100H with the SAI100X100H
To replace the SI100X100H, order the SAI100X100H and confirm the ISO 15552 mounting interface, G1/2 port, and M20x1.5 rod thread. Because this SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if position sensing is needed. For sizing alternatives, the neighboring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore yields 6136 N. Remember that a plain cylinder drifts on air loss; the air cushion only decelerates near stroke end. For load holding, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X100H
- ✓ 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 SI100X100H FAQ
Yes, the SI100X100H is discontinued. The direct replacement is the SAI100X100H. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 100mm stroke, 3927 N force, G1/2 port, and mounting fixtures.
The G1/2 port feeds a 25mm rod. Force output is 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. Operating speed is 30-800 mm/s.
