This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X10S, 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 SI200X10S
The AirTAC Airtac SI200 Standard Cylinder SI200X10S 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 SAI200X10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X10S
The AirTAC SI200X10S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 10mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200X10S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI family introduces lock and valve variants (SAIL, BSAI) absent in the SI line.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |

Where the Airtac SI200 Standard Cylinder SI200X10S Is Used
Heavy Press Operations
Generates 21991 N at 0.7 MPa for high-force stamping, forming, and riveting tasks in automated fabrication lines.
Industrial Clamp Systems
Provides robust 15708 N clamping force at 0.5 MPa to secure heavy castings or large structural components during machining.
Short-Stroke Plunging
The 10mm stroke delivers immediate, high-impact insertion or seating of large industrial components on assembly floors.
Replacing the Airtac SI200 Standard Cylinder SI200X10S with the SAI200X10S
To replace the SI200X10S, order the SAI200X10S and verify the ISO 15552 mounting interface, 10mm stroke, G3/4 port, and M36x2 rod thread. This -S SKU uses a piston magnet for CS1-B/DS1-B switches; the SAI replacement utilizes current AirTAC switches. If sizing down, a 160mm bore yields 10053 N push at 0.5 MPa; if sizing up is impossible, 200mm is the maximum profile option. A plain cylinder drifts on air loss since the 50mm air cushion only decelerates at stroke end, so specify an external rod lock or pilot check valve for load holding. The SAIL or BSAI lock variants offer integrated holding if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
