This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X730S, 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 SI200 Standard Cylinder SI200X730S
The AirTAC SI200 Standard Cylinder SI200X730S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 730mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X730S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X730S
The AirTAC SI200X730S is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore and 730mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is superseded by the SAI200X730S. This direct upgrade shares identical mounting, rod thread (M36x2), and 50mm cushions, while adding a two Y-shaped one-way piston seal for lower start-up pressure. The SAI family also introduces SAIL, SAIF, and BSAI variants absent from the SI line.
The original SI -S magnet supports legacy CS1-B/DS1-B sensors, whereas the SAI uses current AirTAC switches. Remember that standard cylinders drift without live air; the cushion only decelerates. For load holding, specify an external rod lock or the SAIL/BSAI lock variant.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAI200X730S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI200 Standard Cylinder SI200X730S Is Used
Heavy Stamping
Drives large presses and stamping dies requiring up to 21991 N of thrust at 0.7 MPa to form thick metal plates.
Pallet Handling
Indexes heavy loaded pallets on conveyors, utilizing the 801 kg vertical lift capacity to lift and transfer goods safely.
Large Mold Actuation
Actuates substantial injection molds or clamping fixtures where the 3204 kgf maximum force secures industrial tooling.
Replacing the Airtac SI200 Standard Cylinder SI200X730S with the SAI200X730S
To replace the discontinued SI200X730S, order the SAI200X730S. Verify the ISO 15552 mounting interface, 730mm stroke, G3/4 port, and M36x2 rod thread. The -S magnet equates to legacy CS1-B/DS1-B sensors, so upgrade to current AirTAC switches for the SAI. If downsizing, a 160mm bore yields 10053 N push at 0.5 MPa; if upsizing is impossible, 200mm is the maximum profile option. Because this is a 730mm stroke, external guides are strongly recommended to prevent rod bending and excessive side loads. A plain cylinder does not hold load without air; use a pilot check valve or the SAIL/BSAI lock variant for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X730S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200X730S FAQ
Yes, the AirTAC SI200X730S is discontinued. The direct replacement is the SAI200X730S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 730mm stroke, G3/4 port, and mounting interface, but features an upgraded piston seal for longer life.
It features a G3/4 port and delivers 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa push is 21991 N, and 28274 N at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
