This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X90, 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 SI200X90
The AirTAC Airtac SI200 Standard Cylinder SI200X90 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X90, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X90
The AirTAC SI200X90 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 90mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X90. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, force and port size.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. For load holding, the cushion only decelerates; explore SAIL or BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200X90 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200X90 Is Used
Heavy Stamping
Drives large presses and stamping dies requiring high push force over a short 90mm travel.
Injection Molding
Actuates heavy mold halves or clamping fixtures where a robust 200mm bore is necessary.
Press Down Operations
Provides steady downward thrust for riveting or forming assemblies using its 15708 N capacity.
Replacing the Airtac SI200 Standard Cylinder SI200X90 with the SAI200X90
To replace the SI200X90, order the SAI200X90. Confirm the ISO 15552 mounting interface (LB, FA, TC, etc.), the G3/4 port, and the M36x2 rod thread. Because this specific SKU has no -S magnet, it cannot accept position sensors; if switching is needed, select an SAI equivalent with a magnet. Sizing both ways: the 200mm bore yields 15708 N push at 0.5 MPa, while a neighbouring 160mm bore offers 10053 N. If your application requires load holding on air loss, a plain cylinder drifts; use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X90
- ✓ 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 SI200X90 FAQ
Yes, the AirTAC SI200X90 is discontinued. The direct replacement is the SAI200X90. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 200mm bore, 90mm stroke, output force, G3/4 port and mounting accessories.
At 0.5 MPa it provides 15708 N push and 15080 N pull. At 0.7 MPa push is 21991 N, and at 0.9 MPa it is 28274 N. The theoretical max force is 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
