This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX600S, 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 SI200AX600S
The AirTAC SI200 Standard Cylinder SI200AX600S 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 SAI200AX600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX600S
The AirTAC SI200AX600S is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore, 600mm stroke, and a SUS420J2 stainless piston rod. Delivering 15708 N push at 0.5 MPa, its direct replacement is the SAI200AX600S, retaining the same G3/4 port and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

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 SI200AX600S Is Used
Heavy Press Systems
Generates up to 21991 N at 0.7 MPa for high-tonnage forming, stamping, and heavy-duty press operations.
Massive Mold Handling
Moves large injection molds and dies over its 600mm travel, requiring external guides to prevent rod bending.
Replacing the Airtac SI200 Standard Cylinder SI200AX600S with the SAI200AX600S
To replace the SI200AX600S, order the SAI200AX600S. Confirm the ISO 15552 interface, 600mm stroke, G3/4 port, and the built-in magnet for position sensing. The original -A rod denotes SUS420J2 stainless steel; specify this on the SAI if corrosion resistance is required. If sizing alternatives, neighbouring bores shift the 0.5 MPa push force significantly (160mm yields 10053 N, 200mm yields 15708 N). For this 600mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve. The original -S magnet works with legacy CS1-B/DS1-B switches, while the SAI uses current AirTAC sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX600S
- ✓ 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 SI200AX600S FAQ
Yes, the SI200AX600S is discontinued. The direct replacement is the SAI200AX600S. It is dimensionally interchangeable per ISO 15552, keeping the same 200mm bore, 600mm stroke, G3/4 port, and mounting fixtures.
It features a G3/4 port and delivers 15708 N push / 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.
