This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X220STC, 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 SI200X220STC
The AirTAC SI200 Standard Cylinder SI200X220STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 220mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X220STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X220STC
The AirTAC SI200X220STC is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 220 mm stroke. It delivers 15708 N of push force at 0.5 MPa through a G3/4 port. Because this legacy unit is end-of-life, you should order the direct replacement: SAI200X220STC. It preserves the original ISO 15552 mounting interface, TC trunnion accessory, M36x2 rod thread, and output force, dropping directly into existing fixtures.
The SAI upgrade features a modernized piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. The original -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family introduces SAIL, SAIF, and BSAI lock variants that the SI line lacked.

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 SAI200X220STC 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 SI200X220STC Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 15708 N of push force at 0.5 MPa with stable TC trunnion alignment.
Palletizer Lowerator
Lowers heavy product pallets, using the 50 mm adjustable air cushions to decelerate the 220 mm stroke safely at high speeds.
Replacing the Airtac SI200 Standard Cylinder SI200X220STC with the SAI200X220STC
To replace the SI200X220STC, order the SAI200X220STC. Verify your existing setup matches the ISO 15552 interface dimensions, the 200 mm bore, 220 mm stroke, G3/4 port, and TC trunnion mount. The -S code indicates a piston magnet for CS1-B/DS1-B switches; the SAI replacement uses current AirTAC sensors. If you need to size both ways, the neighboring 160 mm bore yields 10053 N push at 0.5 MPa, whereas this 200 mm bore reaches 21991 N at 0.7 MPa. Since this is a plain double-acting cylinder, it cannot hold a load without live air—the 50 mm adjustable cushions only decelerate near stroke end. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X220STC
- ✓ 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 SI200X220STC FAQ
Yes, the AirTAC SI200X220STC is discontinued. The direct replacement is the SAI200X220STC. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 220 mm stroke, G3/4 port, TC mount, and output force.
At 0.5 MPa it pushes 15708 N and pulls 15080 N. At 0.7 MPa push is 21991 N, and at 0.9 MPa it is 28274 N. The theoretical maximum force is 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, operating pressure is 0.15-1.0 MPa, and proof pressure is 1.5 MPa.
