This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1150, 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 SI200X1150
The AirTAC SI200 Standard Cylinder SI200X1150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X1150
The AirTAC SI200X1150 is a discontinued double-acting ISO 15552 profile cylinder, delivering 15708 N push force at 0.5 MPa through a 200 mm bore and 1150 mm stroke. AirTAC replaced this legacy unit with the SAI200X1150, a direct upgrade retaining the exact ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread. The SAI line introduces an upgraded piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life.
Because this specific SKU lacks the -S magnet suffix, it cannot accept a position sensor. Note that plain SI/SAI cylinders drift without live air; for held loads, consider the SAIL or BSAI lock variants, or an external pilot check valve.

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 SAI200X1150 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 SI200X1150 Is Used
Heavy Press Systems
Drives large stamping and forming presses requiring up to 21991 N of thrust at 0.7 MPa over an extended 1150 mm travel distance.
Large Assembly Lifts
Actuates heavy industrial platens and multi-stage lifting platforms where a 200 mm bore and long 1.15 meter extension are essential.
Replacing the Airtac SI200 Standard Cylinder SI200X1150 with the SAI200X1150
To replace the SI200X1150, order the SAI200X1150 and confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), G3/4 port thread, and 1150 mm stroke. Since this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. Sizing both ways: a 160 mm bore offers 10053 N push at 0.5 MPa, while stepping up to max 1.0 MPa pressure yields 3204 kgf. At 1150 mm, this long stroke requires external guides to prevent rod bending and side-load damage. For dead-load holding, the cushion only decelerates; you must add an external rod lock or use the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X1150
- ✓ 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 SI200X1150 FAQ
Yes, the SI200X1150 is discontinued. The direct replacement is the AirTAC SAI200X1150. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 1150 mm stroke, G3/4 port, and mounting fixtures.
It features a G3/4 air port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
