This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX30, 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 SI200BX30
The AirTAC Airtac SI200 Standard Cylinder SI200BX30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX30
The AirTAC SI200BX30 is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa, it features a 200 mm bore, 30 mm stroke, and a G3/4 port. The direct replacement is the SAI200BX30, matching the interface, force, and mounting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. This SKU lacks a magnet, so it cannot take a sensor. For high heat, Viton H seals raise the limit to 150 C; a SUS304 rod option adds corrosion resistance.

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 SI200BX30 Is Used
Heavy Press Operations
Drives large forming and stamping presses requiring 15708 N of push force at 0.5 MPa.
Industrial Clamp Systems
Secures massive fabricated steel components during welding with a robust 3204 kgf maximum.
High-Force Plunging
Executes short 30 mm stroke plunging tasks in heavy machinery with a 50 mm air cushion.
Replacing the Airtac SI200 Standard Cylinder SI200BX30 with the SAI200BX30
To replace the SI200BX30, order the SAI200BX30. Verify the ISO 15552 mounting interface, 200 mm bore, 30 mm stroke, G3/4 port, and M36x2 thread. Because this SKU has no -S magnet, it cannot accept position switches. If you need to hold a load without live air, the cushion only decelerates; use an external pilot check valve or the SAIL lock variant. For force sizing, the 160 mm bore offers 10053 N push at 0.5 MPa, while the 200 mm bore provides 21991 N at 0.7 MPa.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX30
- ✓ 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 SI200BX30 FAQ
Yes, the SI200BX30 is discontinued. The direct replacement is the SAI200BX30. It shares the same ISO 15552 mounting interface, 200 mm bore, 30 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 200 mm bore uses a G3/4 port. It generates 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
