This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X80TC, 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 SI200X80TC
The AirTAC Airtac SI200 Standard Cylinder SI200X80TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X80TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X80TC
The AirTAC SI200X80TC is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke. Built with an extruded aluminum barrel and a TC trunnion mount, it delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200X80TC, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, and output force.
The SAI replacement features an upgraded piston seal utilizing two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S), so it cannot accept CS1-B or DS1-B sensors. For high heat, Viton H seals raise the operating range to 150 C.

Where the Airtac SI200 Standard Cylinder SI200X80TC Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring up to 21991 N of thrust at 0.7 MPa, utilizing the 80 mm stroke for rapid high-force cycles.
Large Mold Clamping
Secures substantial injection molds or heavy fabrication tooling, benefiting from the 50 mm adjustable air cushions to prevent end-of-stroke impact.
Replacing the Airtac SI200 Standard Cylinder SI200X80TC with the SAI200X80TC
To replace the SI200X80TC, order the SAI200X80TC and confirm the TC trunnion mounting, G3/4 port, and M36x2 rod thread match your existing fixture. This direct maintains the ISO 15552 interface for effortless swapping. If you need position feedback, select an SAI variant with the magnet (-S) since this legacy SKU cannot host a sensor. A plain cylinder drifts on air loss because the cushion only decelerates near stroke end; for load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve. If downsizing, a 160 mm bore offers 10053 N push at 0.5 MPa. If upsizing is required, verify your supply can handle the 200 mm bore volume.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X80TC
- ✓ 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 SI200X80TC FAQ
Yes, the SI200X80TC is discontinued. The direct replacement is the SAI200X80TC. It shares the identical ISO 15552 mounting interface, 200 mm bore, 80 mm stroke, G3/4 port, and output force, fitting existing fixtures perfectly while adding an upgraded piston seal.
This double-acting cylinder features a G3/4 air port and an M36x2 rod thread. The thrust output is 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
