This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X200SH, 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 SI200X200SH
The AirTAC SI200 Standard Cylinder SI200X200SH 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 SAI200X200SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X200SH
The AirTAC SI200X200SH is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 200mm stroke. It delivers 15708 N push and 15080 N pull at 0.5 MPa, utilizing a G3/4 air port and M36x2 rod thread. The direct replacement is the SAI200X200SH, matching the interface, force, and port exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SI unit includes a -S magnet for CS1-B/DS1-B switches and a -H Viton seal rated for 0-150 C. Note that a plain cylinder drifts without live air; use an external rod lock or SAIL/BSAI variant for load holding.

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 SAI200X200SH 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 SI200X200SH Is Used
Heavy Press Forming
Generates 15708 N at 0.5 MPa for stamping and forming heavy-gauge metal components in automated fabrication lines.
Pallet Actuation
Provides the high push force needed to lift, index, or divert fully loaded pallets weighing up to 800 kg in distribution hubs.
High-Temp Molding Eject
The Viton H high-temperature seal allows reliable operation up to 150 C for ejecting molded rubber or composite parts.
Replacing the Airtac SI200 Standard Cylinder SI200X200SH with the SAI200X200SH
To replace the SI200X200SH, order the SAI200X200SH direct. Confirm the ISO 15552 mounting interface (LB, FA, TC, etc.), the 200mm stroke, G3/4 port (PT/G/NPT), and the -S/-H options. At 0.5 MPa it yields 15708 N push; if downsizing, a 160mm bore gives 10053 N. If uprating to 0.7 MPa provides 21991 N. Because the stroke is 200mm, verify guide alignment to prevent rod bending. The cushion only decelerates; it does not hold load on air loss, so specify a pilot check valve or the SAIL/BSAI lock variant if drift is unacceptable. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X200SH
- ✓ 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 SI200X200SH FAQ
Yes, the AirTAC SI200X200SH is discontinued. The direct replacement is the SAI200X200SH. It is dimensionally interchangeable per ISO 15552, matching the 200mm bore, 200mm stroke, 15708 N force, G3/4 port, and mounting accessories. You simply order the SAI equivalent.
