This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX80S, 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 SI200BX80S
The AirTAC SI200 Standard Cylinder SI200BX80S 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 SAI200BX80S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX80S
The AirTAC SI200BX80S is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke, delivering 15708 N of push force at 0.5 MPa through its G3/4 port. AirTAC replaced this legacy unit with the SAI200BX80S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, port and accessories, fitting existing fixtures perfectly.
The SAI replacement features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life. The -B rod option specifies SUS304 stainless steel, and the -S magnet supports legacy CS1-B/DS1-B sensors.

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 SAI200BX80S 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 SI200BX80S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping presses requiring 15708 N of push force at 0.5 MPa with stable 80 mm strokes.
Automotive Assembly Jigs
Clamps major automotive chassis components securely in welding jigs using its 801 kg vertical lift capacity.
Palletizer Actuation
Actuates robust palletizer lift gates, moving substantial loads with a theoretical maximum force of 3204 kgf.
Replacing the Airtac SI200 Standard Cylinder SI200BX80S with the SAI200BX80S
To replace the SI200BX80S, order the SAI200BX80S. Confirm the ISO 15552 mounting interface, 200 mm bore, 80 mm stroke, G3/4 port (PT/G/NPT thread), and mounting accessory. The -S magnet enables CS1-B/DS1-B switches, though the SAI uses current AirTAC sensors. Sizing both ways: a 160 mm bore yields 10053 N push @0.5 MPa, while a 200 mm bore at 0.7 MPa yields 21991 N. A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SUS304 -B rod offers corrosion resistance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX80S
- ✓ 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 SI200BX80S FAQ
Yes, the SI200BX80S is discontinued. The direct replacement is the SAI200BX80S. It shares the same ISO 15552 mounting interface, bore, stroke, output force, G3/4 port and mounting, fitting existing fixtures perfectly.
This double-acting cylinder 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 it pushes 21991 N, and 28274 N at 0.9 MPa. The theoretical max force is 3204 kgf at 1.0 MPa.
