This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX600, 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 SI200BX600
The AirTAC Airtac SI200 Standard Cylinder SI200BX600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX600
The AirTAC SI200BX600 is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa through a 200 mm bore and 600 mm stroke, it is replaced by the SAI200BX600. This direct successor shares the exact ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For sensing, note this specific SKU lacks a magnet and cannot take a switch.
The SAI family also introduces lock variants (SAIL, BSAI) absent in the SI line. The standard carbon steel rod can be swapped for a SUS304 stainless option, and Viton H seals raise the operating temperature to 150 C.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Replacing the Airtac SI200 Standard Cylinder SI200BX600 with the SAI200BX600
To replace the discontinued SI200BX600, order the SAI200BX600. Confirm the ISO 15552 mounting interface, 200 mm bore, 600 mm stroke, G3/4 port, and M36x2 thread. Because this SKU lacks the -S magnet, it cannot accept position sensors; if sensing is needed, select an SAI200BX600S. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. With a 600 mm stroke, use external guides to prevent rod bending and side loads. If downsizing, neighbor bores offer less force; if upsizing, 15708 N at 0.5 MPa may be excessive.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX600
- ✓ 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 SI200BX600 FAQ
Yes, the SI200BX600 is discontinued. The direct replacement is the SAI200BX600. It shares the same ISO 15552 mounting interface, 200 mm bore, 600 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 200 mm bore 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 max force of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
