This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX160, 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 SI200BX160
The AirTAC SI200 Standard Cylinder SI200BX160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX160
The AirTAC SI200BX160 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 160mm stroke. Delivering 15708N push force at 0.5MPa via a G3/4 port, it is replaced by the SAI200BX160. This direct upgrade shares the exact ISO 15552 mounting interface, M36x2 thread, and 50mm cushions. The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure, and adds SAIL and BSAI lock variants the SI lacked.
This specific SKU lacks a magnet (-S), so it cannot accept CS1-B or DS1-B sensors. The default carbon-steel rod can be swapped for SUS304 (B) for corrosion resistance, and Viton H seals raise the temperature limit to 150C.

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 SI200BX160 Is Used
Heavy Press Stamping
Drives large stamping presses requiring 15708N push force at 0.5MPa, utilizing the 50mm adjustable cushions to decelerate heavy tooling.
Large Mold Clamping
Secures heavy industrial molds on production lines, where the 200mm bore delivers 28274N of clamping thrust at 0.9MPa operating pressure.
Replacing the Airtac SI200 Standard Cylinder SI200BX160 with the SAI200BX160
To replace the discontinued SI200BX160, order the SAI200BX160. Confirm the ISO 15552 mounting interface matches your fixture, along with the 200mm bore, 160mm stroke, and G3/4 port. Because this non-magnetic SKU cannot hold a position switch, if you need sensing you must select an SAI equivalent with the -S magnet to use current AirTAC switches. Sizing both ways: the neighboring 160mm bore offers 10053N push at 0.5MPa, while this 200mm bore provides 21991N at 0.7MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. For any stroke over 300mm, verify guide alignment to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX160
- ✓ 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 SI200BX160 FAQ
Yes, the SI200BX160 is discontinued. The direct replacement is the SAI200BX160. It is a true ISO 15552 profile cylinder that maintains the same 200mm bore, 160mm stroke, 15708N force, G3/4 port, and mounting interface, fitting existing fixtures perfectly.
This 200mm bore cylinder features a G3/4 air port and an M36x2 rod thread. The thrust ratings are: 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, 28274N push at 0.9MPa, and a theoretical maximum of 3204kgf at 1.0MPa.
