This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX30, 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 SI200AX30
The AirTAC Airtac SI200 Standard Cylinder SI200AX30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX30
The AirTAC SI200AX30 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 30mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200AX30. This direct successor shares the exact ISO 15552 mounting interface, bore, and output force, fitting existing fixtures perfectly.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU uses an SUS420J2 stainless steel rod (-A) and lacks a magnet, meaning it cannot accept position sensors.

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 SI200AX30 Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring massive force, utilizing the 21991 N push capability at 0.7 MPa for reliable heavy-duty actuation.
Industrial Clamp Systems
Secures oversized fabricated components during machining or welding, where the robust 40mm SUS420J2 stainless rod resists corrosion and side loading.
Massive Platen Lowering
Controls the descent of heavy industrial platens, relying on the 50mm adjustable air cushions to smoothly decelerate the load near the stroke end.
Replacing the Airtac SI200 Standard Cylinder SI200AX30 with the SAI200AX30
To replace the SI200AX30, order the SAI200AX30. Verify the ISO 15552 mounting interface, the 200mm bore, 30mm stroke, G3/4 port, and your specific mounting accessory. Because this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, select an SAI model with the S suffix. When sizing, note the 15708 N push force at 0.5 MPa; if stepping down to a 160mm bore, the force drops to 10053 N. For load holding on air loss, note that the air cushion only decelerates; it does not lock. Use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX30
- ✓ 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 SI200AX30 FAQ
Yes, the SI200AX30 is discontinued. The direct replacement is the SAI200AX30. It shares the same ISO 15552 mounting interface, 200mm bore, 30mm stroke, output force, and G3/4 port, fitting directly into your existing fixtures.
This double-acting cylinder features a G3/4 port and delivers a push force of 15708 N and pull of 15080 N at 0.5 MPa. At 0.7 MPa push is 21991 N, and 28274 N at 0.9 MPa. The theoretical max force is 3204 kgf at 1.0 MPa.
