This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X700N, 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 SI200X700N
The AirTAC Airtac SI200 Standard Cylinder SI200X700N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X700N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X700N
The AirTAC SI200X700N is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 700mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI200X700N, a direct replacement sharing the exact ISO 15552 mounting interface, M36x2 rod thread, and 50mm cushions. This SKU uses NBR seals (-N) for -20 to +70 C operation and lacks a magnet, so it cannot accept position switches.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. If you need load holding on air loss, explore the SAIL or BSAI lock variants, as standard cushions only decelerate.

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 SAI200X700N 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 SI200X700N Is Used
Heavy Press Systems
Drives large industrial presses requiring 21991 N push at 0.7 MPa to form thick metal components reliably.
Large Mold Handling
Shifts substantial injection molds over a 700mm span, relying on external guides to prevent rod bending.
Replacing the Airtac SI200 Standard Cylinder SI200X700N with the SAI200X700N
To replace the discontinued SI200X700N, order the SAI200X700N. Verify your ISO 15552 mounting fixtures, the G3/4 air port, and the M36x2 rod thread. Because this 700mm stroke is long, use external guides to prevent rod bending and side-load damage. For sizing, a 160mm bore yields 10053 N push at 0.5 MPa, while stepping up is impossible as 200mm is the largest. Note this non-magnetic SKU cannot take CS1-B/DS1-B sensors. Since standard cylinders drift without air, use a pilot check valve or the SAIL lock variant for suspended loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X700N
- ✓ 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 SI200X700N FAQ
Yes, the SI200X700N is discontinued. The direct replacement is the SAI200X700N. It shares the same ISO 15552 mounting interface, 200mm bore, 700mm stroke, force, G3/4 port, and accessories, fitting directly into existing fixtures.
It features a G3/4 port and provides 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 theoretical max of 3204 kgf at 1.0 MPa.
