This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X200STC, 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 SI200X200STC
The AirTAC SI200 Standard Cylinder SI200X200STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X200STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X200STC
The AirTAC SI200X200STC is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 200mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200X200STC, matching the bore, stroke, force, port and TC trunnion mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family adds SAIL lock and BSAI clamp variants absent in the SI line. Your -S magnet works with 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 SAI200X200STC 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 SI200X200STC Is Used
Heavy Press Forming
Applies the 21991 N push at 0.7 MPa for stamping or forming heavy gauge metal components securely.
Mold Clamping
Holds large industrial molds in place during injection or casting cycles using the 15080 N pull force.
Pallet Lifting
Drives robust lifting arms in automated warehousing, safely moving loads near the 801 kg vertical limit.
Replacing the Airtac SI200 Standard Cylinder SI200X200STC with the SAI200X200STC
To replace the SI200X200STC, order the SAI200X200STC. Verify the ISO 15552 TC trunnion interface, 200mm stroke, G3/4 port, and -S magnet. If downsizing, a 160mm bore yields 10053 N push at 0.5 MPa; if upsizing is impossible, 200mm is the maximum standard profile. For load holding, note that a plain cylinder drifts on air loss as the cushion only decelerates; use an external pilot check valve or the SAIL/BSAI lock variant. At 200mm stroke, side-load is moderate, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X200STC
- ✓ 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 SI200X200STC FAQ
Yes, the SI200X200STC is discontinued. The direct replacement is the SAI200X200STC. It features the same ISO 15552 mounting interface, 200mm bore, 200mm stroke, output force, G3/4 port and TC trunnion mounting, fitting existing fixtures perfectly.
The 200mm bore provides 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s. It uses a 40mm rod, M36x2 thread, and 50mm cushions.
