This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X900S, 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 SI200X900S
The AirTAC SI200 Standard Cylinder SI200X900S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X900S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X900S
The AirTAC SI200X900S is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa through a 200 mm bore and 900 mm stroke, it features a G3/4 port and M36x2 rod thread. The direct replacement is the SAI200X900S, matching the interface, bore, stroke, force, port and mounting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF and BSAI variants the SI lacked. This -S model uses CS1-B/DS1-B sensors.

Where the Airtac SI200 Standard Cylinder SI200X900S Is Used
Heavy Press Systems
Generates up to 28274 N at 0.9 MPa for high-tonnage forming, stamping and heavy industrial press operations.
Large Payload Lifts
Raises substantial masses with a safe vertical lift capacity around 801 kg, ideal for heavy material elevation.
Bulk Material Routing
Shifts heavy pallets or large structural components across production lines over its 900 mm extension.
Replacing the Airtac SI200 Standard Cylinder SI200X900S with the SAI200X900S
To replace this SI200X900S, order the SAI200X900S. Confirm the ISO 15552 mounting interface, 200 mm bore, 900 mm stroke, G3/4 port (PT/G/NPT) and mounting accessory. The -S magnet enables CS1-B/DS1-B switches; the SAI uses current AirTAC switches. Sizing both ways: the 160 mm neighbor yields 10053 N push at 0.5 MPa, while this 200 mm bore hits 21991 N at 0.7 MPa. A plain cylinder drifts without live air; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. For the 900 mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X900S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
