This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X700S, 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 SI200X700S
The AirTAC Airtac SI200 Standard Cylinder SI200X700S 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 SAI200X700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X700S
The AirTAC SI200X700S is a discontinued double-acting ISO 15552 profile cylinder delivering 15708 N push force at 0.5 MPa through a 200 mm bore and 700 mm stroke. It features a G3/4 port, M36x2 rod thread, and 50 mm adjustable air cushions. AirTAC replaced this legacy unit with the SAI200X700S, a direct upgrade retaining the exact ISO 15552 mounting interface, output force, and porting.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also adds SAIL and BSAI lock variants absent from the SI line, while the original -S magnet supports legacy 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 | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAI200X700S 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 SI200X700S Is Used
Heavy Stamp Pressing
Generates up to 21991 N at 0.7 MPa for forming and stamping thick metal components in automated fabrication lines.
Large Mold Clamping
Secures heavy injection molds via the ISO 15552 interface, providing rigid 15708 N holding at 0.5 MPa.
Replacing the Airtac SI200 Standard Cylinder SI200X700S with the SAI200X700S
To replace the SI200X700S, order the SAI200X700S. Verify your existing fixture matches the ISO 15552 mounting interface, 200 mm bore, 700 mm stroke, G3/4 port, and -S magnet configuration. If you need higher force, the adjacent bore is 160 mm (10053 N push @0.5 MPa); if you need less, consider dropping to 125 mm (6136 N push @0.5 MPa). Because this is a 700 mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X700S
- ✓ 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 SI200X700S FAQ
Yes, the AirTAC SI200X700S is discontinued. The direct replacement is the SAI200X700S. It shares the identical ISO 15552 mounting interface, 200 mm bore, 700 mm stroke, force, and G3/4 port, fitting existing fixtures perfectly while upgrading the piston seal.
This double-acting cylinder uses 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 theoretical max of 3204 kgf at 1.0 MPa. It operates at 30-500 mm/s.
