This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X190S, 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 SI200X190S
The AirTAC SI200 Standard Cylinder SI200X190S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X190S
The AirTAC SI200X190S is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 190 mm stroke. Delivering 15708 N push force at 0.5 MPa through a G3/4 port, it is replaced by the SAI200X190S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke and output force, fitting existing fixtures perfectly.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked. The -S magnet works with CS1-B/DS1-B sensors; SAI uses current AirTAC switches.

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 SAI200X190S 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 SI200X190S Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring 21991 N push at 0.7 MPa to shape thick metal plates.
Industrial Clamp Systems
Secures heavy fabricated steel structures during welding or machining with a massive 3204 kgf max holding capacity.
Replacing the Airtac SI200 Standard Cylinder SI200X190S with the SAI200X190S
To replace the SI200X190S, order the SAI200X190S. Confirm the ISO 15552 mounting interface, 200 mm bore, 190 mm stroke, G3/4 port (PT/G/NPT), M36x2 rod thread and mounting accessory. The -S magnet enables position sensing. Neighbouring bores are 160 mm (10053 N [email protected]) and 125 mm (6136 N). For strokes >=300 mm, use guide rails to prevent rod bending and side loads. A plain cylinder drifts on air loss; cushions only decelerate. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X190S
- ✓ 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 SI200X190S FAQ
Yes, the SI200X190S is discontinued. The direct replacement is the SAI200X190S. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 190 mm stroke, output force, G3/4 port and mounting interface.
It features a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. It operates at 30-500 mm/s with a 50 mm adjustable cushion.
