This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X430, 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 SI100X430
The AirTAC Airtac SI100 Standard Cylinder SI100X430 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 430mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X430, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X430
The AirTAC SI100X430 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 430mm stroke. Delivering 3927 N push force at 0.5 MPa via a G1/2 port, it is replaced by the SAI100X430. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force and port, fitting existing fixtures perfectly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. Note this SKU has no magnet and cannot take a sensor. For load holding, the cushion only decelerates; use a pilot check valve or SAIL lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X430 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI100X430 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 SI100X430 Is Used
Heavy Press Clamping
Applies the 5497 N push force at 0.7 MPa to secure heavy metal components during machining and pressing operations.
Pallet Diverting
Handles large 430mm strokes to push heavy pallets across transfer lines, requiring external guides to prevent rod bending.
Replacing the Airtac SI100 Standard Cylinder SI100X430 with the SAI100X430
To replace the SI100X430, order the SAI100X430. Confirm the ISO 15552 mounting interface, 100mm bore, 430mm stroke, G1/2 port (PT/G/NPT) and mounting accessory. Because this SKU lacks a magnet (-S), it cannot accept CS1-B/DS1-B sensors. Sizing both ways: the 80mm bore yields 2513 N [email protected], while the 125mm bore yields 6136 N. At 430mm stroke, use external guides to prevent rod bending and side loads. A plain cylinder drifts on air loss; for held loads use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X430
- ✓ 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 SI100X430 FAQ
Yes, the AirTAC SI100X430 is discontinued. The direct replacement is the SAI100X430. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 430mm stroke, 3927 N force, G1/2 port and mounting interface.
The 100mm bore uses a G1/2 port. Force ratings 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 theoretical max of 801 kgf at 1.0 MPa. Speed is 30-800 mm/s.
