This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX290, 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 SI200AX290
The AirTAC Airtac SI200 Standard Cylinder SI200AX290 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 290mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX290, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX290
The AirTAC SI200AX290 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 290mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI200AX290, a direct upgrade retaining the exact interface, stroke, and force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU uses an SUS420J2 stainless steel rod (-A) and lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor.

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 SAI200AX290 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 SI200AX290 Is Used
Heavy Press Forming
Generates 21991 N at 0.7 MPa for stamping and forming thick metal plates in automotive assembly lines.
Pallet Lift Gates
Provides the robust vertical thrust needed to raise loaded pallet gates, safely handling substantial weights.
Injection Molding
Clamps large molds securely with up to 3204 kgf theoretical max force at 1.0 MPa operating pressure.
Replacing the Airtac SI200 Standard Cylinder SI200AX290 with the SAI200AX290
To replace the SI200AX290, order the SAI200AX290. Verify your ISO 15552 mounting interface, 290mm stroke, G3/4 port, and M36x2 rod thread. Because this SKU has no magnet (-S), it cannot support position sensing; if switches are needed, select a magnet-equipped SAI. This 200mm bore yields 15708 N at 0.5 MPa—if less force is acceptable, a 160mm bore provides 10053 N. For load holding, note that a standard cylinder drifts on air loss; the cushion only decelerates. Use an external pilot check valve or the SAIL/BSAI lock variants. At 290mm stroke, ensure guide rails carry side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX290
- ✓ 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 SI200AX290 FAQ
Yes, the SI200AX290 is discontinued. The direct replacement is the SAI200AX290. It shares the same ISO 15552 mounting interface, 200mm bore, 290mm stroke, force, and G3/4 port, fitting existing fixtures perfectly.
It features a G3/4 port. Force ratings are: 15708 N push and 15080 N pull at 0.5 MPa; 21991 N push at 0.7 MPa; 28274 N push at 0.9 MPa; with a theoretical max of 3204 kgf at 1.0 MPa.
