This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX210, 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 SI200AX210
The AirTAC Airtac SI200 Standard Cylinder SI200AX210 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 210mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX210, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX210
The AirTAC SI200AX210 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 210mm stroke. It delivers 15708N push and 15080N pull at 0.5MPa, utilizing a G3/4 port. AirTAC replaced this legacy unit with the SAI200AX210, a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI200AX210 features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU uses a SUS420J2 stainless rod (-A) and lacks a magnet, meaning it cannot accept a CS1-B/DS1-B sensor.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAI200AX210 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI200 Standard Cylinder SI200AX210 Is Used
Heavy Press Forming
Applies the 21991N push force at 0.7MPa for stamping and forming large metal panels in automotive assembly lines.
Pallet Lifting
Raises loaded pallets up to the 801kg vertical lift capacity, relying on the robust 40mm piston rod for stability.
Mining Equipment Actuation
Utilizes the SUS420J2 stainless rod option to resist corrosion while actuating heavy separation gates in mineral processing.
Replacing the Airtac SI200 Standard Cylinder SI200AX210 with the SAI200AX210
To replace the SI200AX210, order the SAI200AX210. Verify your ISO 15552 mounting fixture, the 210mm stroke, and the G3/4 port. Because this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B switches; order a magnet-equipped SAI if sensing is required. The -A rod specifies SUS420J2 stainless steel for corrosion resistance. Sizing down, a 160mm bore yields 10053N push at 0.5MPa; sizing up is not available in standard ISO 15552 ranges. For stroke lengths over 300mm, guide external rods to prevent side-load bending. A plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX210
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
