This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X415S, 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 SI200X415S
The AirTAC SI200 Standard Cylinder SI200X415S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 415mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X415S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X415S
The AirTAC SI200X415S is a discontinued double-acting ISO 15552 profile cylinder. Built with an extruded aluminum barrel, it delivers 15708 N push force at 0.5 MPa through a 200 mm bore, 415 mm stroke, and G3/4 port. Because this legacy SI unit is end-of-life, the direct replacement is the SAI200X415S. It shares the same ISO 15552 mounting interface, bore, stroke, output force, port size, and accessories, fitting existing fixtures perfectly.
The SAI upgrade introduces an advanced piston seal featuring two Y-shaped one-way elements for low start-up pressure and extended life. The original SI utilized CS1-B/DS1-B sensors via its magnet, while the SAI family also adds SAIL lock and BSAI clamp-lock variants absent in the legacy 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 SAI200X415S 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 SI200X415S Is Used
Heavy Press Stamping
Drives large tonnage metal forming and stamping presses where the 21991 N push force at 0.7 MPa is required for deep draw operations.
Large Mold Clamping
Secures heavy injection molds or industrial fixtures, relying on the 3204 kgf theoretical maximum force at 1.0 MPa operating pressure.
Replacing the Airtac SI200 Standard Cylinder SI200X415S with the SAI200X415S
To replace the SI200X415S, order the SAI200X415S. Confirm the ISO 15552 mounting interface, the 415 mm stroke, the G3/4 port, and your mounting accessory (such as LB foot or TC trunnion). The -S magnet equips it for current AirTAC switches, replacing the legacy CS1-B/DS1-B sensors. Sizing both ways: a neighboring 160 mm bore yields 10053 N push at 0.5 MPa, while stepping up is unnecessary as this 200 mm bore already hits 21991 N at 0.7 MPa. Remember, a plain cylinder drifts without live air; for load holding, specify the SAIL or BSAI lock variant, or use an external rod lock. Finally, at 415 mm stroke, prevent rod bending by guiding the load externally to avoid side-loading.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X415S
- ✓ 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 SI200X415S FAQ
Yes, the AirTAC SI200X415S is discontinued. The direct replacement is the SAI200X415S. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 415 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 port and generates 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa it pushes 21991 N, and at 0.9 MPa it reaches 28274 N. The theoretical maximum force is 3204 kgf at 1.0 MPa.
