This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X336SFB, 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 SI200X336SFB
The AirTAC Airtac SI200 Standard Cylinder SI200X336SFB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 336mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X336SFB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X336SFB
The AirTAC SI200X336SFB is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 336 mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI200X336SFB, matching the interface, force, and FB flange mount.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. The SAI family adds SAIL and BSAI lock variants the SI lacked. This -S SKU uses CS1-B/DS1-B sensors.

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 SAI200X336SFB 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 SI200X336SFB Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring up to 21991 N of thrust at 0.7 MPa with stable FB flange mounting.
Massive Platen Lowering
Controls the descent of 801 kg platens in vertical lift setups, demanding external guides to manage the 336 mm stroke side loads.
Replacing the Airtac SI200 Standard Cylinder SI200X336SFB with the SAI200X336SFB
To replace the SI200X336SFB, order the SAI200X336SFB. Confirm the ISO 15552 interface, 200 mm bore, 336 mm stroke, G3/4 port, FB flange mount, and -S magnet for CS1-B/DS1-B switches. If downsizing, neighbor bores (160 mm) yield 10053 N push at 0.5 MPa; if upsizing pressure, 0.7 MPa yields 21991 N. A plain cylinder drifts on air loss—cushions only decelerate—so use an external rod lock or SAIL/BSAI variant for load holding. For the 336 mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X336SFB
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
