This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X80SH, 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 SI200X80SH
The AirTAC SI200 Standard Cylinder SI200X80SH 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 SAI200X80SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X80SH
The AirTAC SI200X80SH is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 80 mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X80SH. This direct upgrade shares the exact ISO 15552 mounting interface, M36x2 thread, and 50 mm cushions. The -H denotes Viton seals for 0-150 C heat, while -S adds a piston magnet for CS1-B/DS1-B sensors.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI 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 SAI200X80SH 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 SI200X80SH Is Used
Heavy Stamping
Drives large presses and stamping dies requiring 21991 N output at 0.7 MPa, using the 50 mm cushions to absorb high impact energy.
High-Temp Actuation
Operates in 0-150 C thermal environments using the Viton H seal option to maintain reliable 15708 N push force without degradation.
Replacing the Airtac SI200 Standard Cylinder SI200X80SH with the SAI200X80SH
To replace the SI200X80SH, order the SAI200X80SH, confirming the ISO 15552 mounting interface, 80 mm stroke, G3/4 port, and magnet. If you need to scale, neighbouring bores shift the 0.5 MPa push force significantly: a 160 mm bore yields 10053 N, while a 125 mm bore provides 6136 N. Because this is a plain cylinder, it will not hold a load without live air; the 50 mm cushions only decelerate near stroke end. For secure holding, specify an external pilot check valve or the SAIL/BSAI lock variant. The -H Viton seal handles 0-150 C environments.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X80SH
- ✓ 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 SI200X80SH FAQ
Yes, the SI200X80SH is discontinued. The direct replacement is the SAI200X80SH. It shares the identical ISO 15552 mounting interface, 200 mm bore, 80 mm stroke, output force, G3/4 port, and accessories, fitting directly into existing fixtures.
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. 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. Operating speed is 30-500 mm/s.
