This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X15, 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 SI200X15
The AirTAC Airtac SI200 Standard Cylinder SI200X15 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 15mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X15, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X15
The AirTAC SI200X15 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 15mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. As an end-of-line unit, it is replaced by the SAI200X15 direct, which maintains identical ISO 15552 mounting dimensions, bore, stroke, and output force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and longevity. This SKU lacks a magnet and cannot take a sensor. For high heat, Viton H seals extend operation to 150 C.

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

Where the Airtac SI200 Standard Cylinder SI200X15 Is Used
Heavy Press Operations
Drives high-tonnage stamping and forming presses where the 15708 N output at 0.5 MPa is required to shape thick plate metal.
Massive Payload Elevation
Lifts heavy industrial platens or molds, utilizing the computed 801 kg vertical lift capacity to move substantial loads safely.
Robotic Clamping Stations
Secures oversized fabrications in automated welding cells, providing rigid holding via the 40mm rod without lateral deflection.
Replacing the Airtac SI200 Standard Cylinder SI200X15 with the SAI200X15
To replace the SI200X15, order the SAI200X15 and verify your ISO 15552 mounting interface, M36x2 rod thread, and G3/4 port. Because this specific SKU lacks a magnet (-S), it cannot accept CS1-B/DS1-B sensors; order a magnet-equipped version if position detection is required. Sizing down, a 160mm bore yields 10053 N at 0.5 MPa; sizing up is not possible as 200mm is the largest. Note that a plain cylinder drifts on air loss—the 50mm cushions only decelerate. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X15
- ✓ 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 SI200X15 FAQ
Yes, the SI200X15 is discontinued. The direct replacement is the SAI200X15. It shares the identical ISO 15552 mounting interface, 200mm bore, 15mm stroke, G3/4 port, and force ratings, fitting directly into existing fixtures.
It 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, at 0.9 MPa it is 28274 N, and the theoretical max is 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
