This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X900TC, 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 SI200X900TC
The AirTAC SI200 Standard Cylinder SI200X900TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X900TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X900TC
The AirTAC SI200X900TC is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 900mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this EOL unit with the SAI200X900TC, a direct upgrade retaining the exact ISO 15552 mounting interface, TC trunnion mount, and output force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants absent in the SI line. Note this SKU lacks a magnet and cannot take a sensor.

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 SAI200X900TC 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 SI200X900TC Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 15708 N of push force at 0.5 MPa to shape thick steel plates.
Automated Assembly Line
Shifts heavy machinery frames along the production floor using the TC trunnion mount to handle articulated pivot motion.
Replacing the Airtac SI200 Standard Cylinder SI200X900TC with the SAI200X900TC
To replace the SI200X900TC, order the SAI200X900TC. Verify the ISO 15552 TC trunnion interface, 200mm bore, 900mm stroke, G3/4 port (PT/G/NPT thread), and M36x2 rod thread. Because this is a non-magnet SKU, it cannot accept CS1-B/DS1-B sensors; order a -S variant if position sensing is required. Sizing both ways: a 160mm bore yields 10053 N push at 0.5 MPa, while a 200mm bore hits 21991 N at 0.7 MPa. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 900mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X900TC
- ✓ 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 SI200X900TC FAQ
Yes, the SI200X900TC is discontinued. The direct replacement is the SAI200X900TC. It is dimensionally interchangeable per ISO 15552, matching the 200mm bore, 900mm stroke, G3/4 port, TC mount, and output force, so it fits existing fixtures directly.
The 200mm bore uses a G3/4 port. It generates 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical max force is 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
