This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX290, 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 SI200BX290
The AirTAC Airtac SI200 Standard Cylinder SI200BX290 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 SAI200BX290, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX290
The AirTAC SI200BX290 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 290 mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200BX290. This direct successor matches the exact interface, bore, stroke, output force, and mounting hardware. The SAI features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
Note this specific SKU lacks a magnet (-S) and cannot accept position sensors. The SAI family also introduces SAIL, SAIF, and BSAI lock or self-valve variants absent in the legacy SI line.

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 SAI200BX290 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 SI200BX290 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 15708 N of push force at 0.5 MPa with robust 50 mm adjustable cushions.
Large Mold Clamping
Secures heavy injection molds using the 40 mm carbon steel rod, relying on continuous air pressure to maintain force.
Replacing the Airtac SI200 Standard Cylinder SI200BX290 with the SAI200BX290
To replace the SI200BX290, order the SAI200BX290. Verify the ISO 15552 mounting interface, 200 mm bore, 290 mm stroke, G3/4 port (PT/G/NPT thread options), and M36x2 rod thread. Because this SKU lacks a magnet, it cannot support legacy CS1-B/DS1-B sensors; order an SAI-S variant if position detection is needed. For sizing alternatives, a neighbouring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore hits 21991 N at 0.7 MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding. At 290 mm stroke, use guide rails to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX290
- ✓ 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 SI200BX290 FAQ
Yes, the SI200BX290 is discontinued. The direct replacement is the SAI200BX290. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 290 mm stroke, G3/4 port, and mounting fixtures.
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. Operating speed is 30-500 mm/s.
