This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1500S, 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 SI200X1500S
The AirTAC SI200 Standard Cylinder SI200X1500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X1500S
The AirTAC SI200X1500S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 1500mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X1500S. This direct successor shares the exact ISO 15552 mounting interface, bore, and output force. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure, and introduces SAIL, SAIF, and BSAI lock variants the SI lacked.
The original -S magnet supports CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. Rod material options include carbon steel, SUS420J2, or SUS304, with Viton H seals for high-heat duties.

Where the Airtac SI200 Standard Cylinder SI200X1500S Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring high thrust, utilizing the 21991 N push force at 0.7 MPa to shape heavy gauge materials.
Bulk Material Diversion
Shifts massive diverters on high-capacity bulk conveyor lines, relying on the 1500mm stroke to clear wide transport paths.
Replacing the Airtac SI200 Standard Cylinder SI200X1500S with the SAI200X1500S
To replace the SI200X1500S, order the SAI200X1500S keeping the identical 200mm bore, 1500mm stroke, M36x2 thread, G3/4 port, and ISO 15552 mounting. Verify your port thread (PT, G, or NPT) and mounting accessory. Because this is a 1500mm stroke, external guides are critical to prevent rod bending and side-load damage. A plain cylinder drifts without air and the 50mm cushions only decelerate; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. If downsizing, a 160mm bore yields 10053 N push at 0.5 MPa; if upsizing is needed, note 200mm is the largest standard profile.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X1500S
- ✓ 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 SI200X1500S FAQ
Yes, the SI200X1500S is discontinued. The direct replacement is the SAI200X1500S. It is dimensionally interchangeable per the ISO 15552 mounting interface, matching the 200mm bore, 1500mm stroke, force, G3/4 port, and mounting fixtures.
This double-acting cylinder uses a G3/4 air port. It generates 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 maximum of 3204 kgf at 1.0 MPa.
