This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X560STC, 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 SI200X560STC
The AirTAC SI200 Standard Cylinder SI200X560STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 560mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X560STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X560STC
The AirTAC SI200X560STC is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 560mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, its direct replacement is the SAI200X560STC. This current-production SAI model maintains the exact TC trunnion mounting, M36x2 rod thread, and 50mm cushions, ensuring a true dimensional interchange per ISO 15552.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches.

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 SI200X560STC Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 21991 N push force at 0.7 MPa to shape thick plate materials.
Mold Clamping Station
Secures heavy injection molds via the TC trunnion mount, utilizing the 50mm adjustable cushions for deceleration.
Replacing the Airtac SI200 Standard Cylinder SI200X560STC with the SAI200X560STC
To replace the SI200X560STC, order the SAI200X560STC. Confirm the ISO 15552 TC trunnion interface, 200mm bore, 560mm stroke, G3/4 port, and the -S magnet. If sizing both ways, neighbouring bores shift the 0.5 MPa push force significantly (160mm yields 10053 N; no larger standard bore exists). Because this is a 560mm stroke, external guides are strongly recommended to prevent rod bending and excessive side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X560STC
- ✓ 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 SI200X560STC FAQ
Yes, the AirTAC SI200X560STC is discontinued. The direct replacement is the SAI200X560STC. It is dimensionally interchangeable per ISO 15552, keeping the same 200mm bore, 560mm stroke, G3/4 port, and TC mounting interface.
The 200mm bore features a G3/4 port. It 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 theoretical max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
