This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX10S, 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 SI200AX10S
The AirTAC SI200 Standard Cylinder SI200AX10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 10mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX10S
The AirTAC SI200AX10S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 10mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. AirTAC replaced it with the SAI200AX10S, a direct upgrade sharing the exact ISO 15552 mounting interface, M36x2 thread, and 50mm cushions.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. This specific unit has a SUS420J2 stainless rod (-A) and a magnet (-S) for CS1-B/DS1-B sensors.

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 SI200AX10S Is Used
Heavy Press Clamping
Generates 21991 N at 0.7 MPa to secure large fabricated steel panels during robotic welding and machining operations.
Pallet Ejection
Provides the robust push force needed to eject loaded pallets from heavy-duty packaging conveyors without bounce.
Mold Separation
Uses the short 10mm stroke and high pull force to break loose large injection molds during initial part ejection.
Replacing the Airtac SI200 Standard Cylinder SI200AX10S with the SAI200AX10S
To replace the SI200AX10S, order the SAI200AX10S, confirming the ISO 15552 interface, 200mm bore, 10mm stroke, G3/4 port, and SUS420J2 rod. It drops into existing fixtures. If you need less force, the 160mm bore offers 10053 N [email protected]; if more, note this bore maxes at 3204 kgf. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for holding, or specify the SAIL or BSAI lock variant. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX10S
- ✓ 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 SI200AX10S FAQ
Yes, the SI200AX10S is discontinued. The direct replacement is the SAI200AX10S. It is dimensionally interchangeable per ISO 15552, keeping the same 200mm bore, 10mm stroke, force, G3/4 port, and mounting accessories.
It uses a G3/4 port. Force output is 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 is 3204 kgf at 1.0 MPa.
