This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX110, 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 SI200AX110
The AirTAC Airtac SI200 Standard Cylinder SI200AX110 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 110mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX110, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX110
The AirTAC SI200AX110 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 110mm stroke. Built for heavy-duty tasks, it delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200AX110, matching the bore, stroke, force, and ISO 15552 mounting interface for existing fixtures.
This SKU features a SUS420J2 stainless steel rod (option A) for corrosion resistance but lacks a magnet, meaning it cannot accept a position switch. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |

Where the Airtac SI200 Standard Cylinder SI200AX110 Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring substantial thrust, utilizing the 15708 N push force at 0.5 MPa to shape thick metal components reliably.
Large Mold Clamping
Secures oversized injection molds on production lines, using the robust 40mm SUS420J2 stainless rod to resist corrosion in humid industrial environments.
Replacing the Airtac SI200 Standard Cylinder SI200AX110 with the SAI200AX110
To replace the SI200AX110, order the SAI200AX110, confirming the ISO 15552 interface, 200mm bore, 110mm stroke, G3/4 port, and SUS420J2 rod. Because this SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; you must use external physical stops or add a sensing setup. If dropping down to a 160mm bore reduces the footprint, expect about 10053 N push at 0.5 MPa. If upsizing is needed, the 200mm bore already maxes out the standard line at 3204 kgf. Note that a plain cylinder drifts on air loss; the 50mm cushions only decelerate. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX110
- ✓ 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 SI200AX110 FAQ
Yes, the SI200AX110 is discontinued. The direct replacement is the SAI200AX110. It features the same ISO 15552 mounting interface, 200mm bore, 110mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
This double-acting cylinder uses a G3/4 air port. It delivers a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force is 21991 N, and the theoretical maximum force is 3204 kgf at 1.0 MPa.
