This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1400, 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.

The AirTAC SI200 Standard Cylinder SI200X1400 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1400mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1400, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI200X1400 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 1400 mm stroke. Generating 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X1400. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI200X1400 features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Since this specific SI SKU lacks the -S magnet suffix, it cannot accept a position switch.

The SAI200X1400 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Drives large stamping and forming presses requiring up to 28274 N of thrust at 0.9 MPa over a long 1400 mm travel.
Indexing heavy automotive subframes or large machinery beds over extended 1.4 meter strokes with guided tooling.
To replace the SI200X1400, order the SAI200X1400 and verify your ISO 15552 mounting interface, M36x2 rod thread, G3/4 port, and 50 mm cushions. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; add the S suffix on SAI if you need switches. When sizing both ways, a 160 mm bore yields 10053 N push at 0.5 MPa, while a 200 mm bore hits 21991 N at 0.7 MPa. Note that a plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding. Finally, the 1400 mm stroke demands external guides to prevent rod bending and side-load damage.
Replacement checklist
Yes, the SI200X1400 is discontinued. The direct replacement is the SAI200X1400, which shares the identical ISO 15552 mounting interface, 200 mm bore, 1400 mm stroke, output force, G3/4 port, and accessories.
It features a G3/4 port and provides 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical maximum of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI200X1400 replacement — usually within 7-8 hours.
