This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X220S, 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 SI200X220S
The AirTAC SI200 Standard Cylinder SI200X220S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 220mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X220S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X220S
The AirTAC SI200X220S is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 220 mm stroke. Delivering 15708 N push force at 0.5 MPa, it features a G3/4 port, M36x2 rod thread, and a piston magnet for CS1-B/DS1-B switches. AirTAC replaced this EOL unit with the SAI200X220S.
The SAI200X220S is a direct replacement matching the ISO 15552 mounting interface, bore, stroke, output force, and port size. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life.

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 SI200X220S Is Used
Heavy Stamping
Drives large presses and stamping dies requiring 15708 N push force at 0.5 MPa with stable 220 mm travel.
Injection Molding
Actuates heavy molds and clamping fixtures where the G3/4 port and 50 mm cushions manage high volume air flow.
Replacing the Airtac SI200 Standard Cylinder SI200X220S with the SAI200X220S
To replace the SI200X220S, order the SAI200X220S and confirm the ISO 15552 mounting interface, G3/4 port, and magnet option match your fixture. The SAI family adds SAIL (air-released lock) and BSAI (clamp-lock) variants the SI lacked; use these or an external pilot check valve for load holding, as a plain cylinder drifts on air loss and its cushion only decelerates. At 220 mm stroke, side-load and rod-bending risks are low, but ensure guide alignment. If downsizing, neighbor bores (160 mm) offer 10053 N push at 0.5 MPa; if upsizing, note the 3204 kgf max force at 1.0 MPa.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X220S
- ✓ 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 SI200X220S FAQ
Yes, the SI200X220S is discontinued. The direct replacement is the SAI200X220S. It shares the same ISO 15552 mounting interface, 200 mm bore, 220 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The SI200X220S delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a maximum theoretical force of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
