This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X930S, 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 SI100X930S
The AirTAC Airtac SI100 Standard Cylinder SI100X930S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 930mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X930S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X930S
The AirTAC SI100X930S is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 930 mm stroke. It delivers 3927 N push force at 0.5 MPa via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X930S, a direct upgrade retaining the exact interface, stroke, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. It also introduces lock and valve variants the SI lacked, like the SAIL and BSAI.

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 SAI100X930S 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 SI100X930S Is Used
Long-Stroke Diversion
Handles large package routing on conveyors where the 930 mm travel pushes heavy pallets cleanly to auxiliary lines.
Vertical Material Lowering
Lowers 200 kg bulk material platforms using its 3927 N push force at 0.5 MPa, requiring external guides for the long rod.
High-Bay Extraction
Extracts wide totes from deep storage racking, leveraging the 100 mm bore's substantial thrust over extended distances.
Replacing the Airtac SI100 Standard Cylinder SI100X930S with the SAI100X930S
To replace the SI100X930S, order the SAI100X930S. Verify your ISO 15552 mounting interface, 930 mm stroke, G1/2 port, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). If sizing up or down, adjacent bores are 80 mm (2513 N push @0.5) and 125 mm (6136 N push @0.5). Note that a 930 mm stroke creates high rod-bending leverage; use external guides to prevent side-load damage. A plain cylinder drifts without live air, so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X930S
- ✓ 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 SI100X930S FAQ
Yes, the SI100X930S is discontinued. The direct replacement is the SAI100X930S. It is dimensionally interchangeable per ISO 15552, keeping the same 100 mm bore, 930 mm stroke, G1/2 port, and mounting fixtures.
The bore is 100 mm with a G1/2 air port. At 0.5 MPa it pushes 3927 N and pulls 3681 N. At 0.7 MPa it pushes 5497 N, and 7068 N at 0.9 MPa. The theoretical max force is 801 kgf at 1.0 MPa.
