This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X600STC, 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 SI200X600STC
The AirTAC SI200 Standard Cylinder SI200X600STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X600STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X600STC
The AirTAC SI200X600STC is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 600mm stroke. Generating 15708 N push force at 0.5 MPa, it is replaced direct by the SAI200X600STC, retaining the identical TC trunnion mount, G3/4 port, and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

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 SAI200X600STC 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 SI200X600STC Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 15708 N push force at 0.5 MPa over a 600mm cycle.
Large Assembly Fixture
Actuates massive clamps via the TC trunnion mount, handling the 3204 kgf max theoretical force at 1.0 MPa.
Replacing the Airtac SI200 Standard Cylinder SI200X600STC with the SAI200X600STC
To replace the SI200X600STC, order the SAI200X600STC ensuring the ISO 15552 interface, 200mm bore, 600mm stroke, G3/4 port, TC trunnion mount, and -S magnet match. The SAI uses current AirTAC switches instead of the legacy CS1-B/DS1-B sensors. Neighbouring bores are 160mm (10053 N @0.5 MPa) and no larger standard size. At 600mm stroke, use external guides to prevent rod bending and side-load wear. The air cushion only decelerates; it does not hold load on air loss, so add a pilot check valve or SAIL/BSAI lock variant for holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X600STC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
