This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX600, 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 SI200AX600
The AirTAC Airtac SI200 Standard Cylinder SI200AX600 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 SAI200AX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX600
The AirTAC SI200AX600 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 600mm stroke. Built for heavy-duty thrust, it delivers a push force of 15708 N at 0.5 MPa. AirTAC replaced this legacy unit with the SAI200AX600, a direct upgrade retaining the exact G3/4 port, M36x2 rod thread, and ISO 15552 mounting interface.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU lacks a magnet (-S), so it cannot accept position sensors. For load holding, note that the air cushion only decelerates; use an external rod lock or pilot check valve.

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 SI200AX600 Is Used
Heavy Stamping Press
Drives large metalforming dies requiring massive push force, using the 50mm adjustable cushions to absorb high kinetic energy at stroke ends.
Large Mold Clamping
Secures substantial injection molds with 15708 N thrust at 0.5 MPa, relying on the robust 40mm carbon steel rod for rigid holding.
Replacing the Airtac SI200 Standard Cylinder SI200AX600 with the SAI200AX600
To replace the SI200AX600, order the SAI200AX600. Verify your ISO 15552 mounting fixtures, the G3/4 air port, and the M36x2 rod thread. Because this 600mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load wear. This non-magnetic SKU cannot take switches; if you need sensing, select an SAI model with the S suffix for current AirTAC sensors. For sizing, a 160mm bore offers 10053 N push at 0.5 MPa, while stepping up is unnecessary here. If your application requires the SUS420J2 stainless rod (the -A option), specify it on the SAI order. For load holding on air loss, explore the SAIL or BSAI lock variants, as standard cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX600
- ✓ 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 SI200AX600 FAQ
Yes, the AirTAC SI200AX600 is discontinued. The direct replacement is the SAI200AX600. It shares the same ISO 15552 mounting interface, 200mm bore, 600mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
This double-acting cylinder uses a G3/4 air port. It generates a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force is 21991 N, and the theoretical maximum is 3204 kgf at 1.0 MPa.
