This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1500, 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 SI200X1500 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 SAI200X1500, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI200X1500 is a discontinued double-acting ISO 15552 profile cylinder with a 1500 mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. AirTAC replaced this legacy unit with the SAI200X1500. The SAI is a direct upgrade: it preserves the exact ISO 15552 mounting interface, bore, stroke, output force, port size and accessories, so it fits existing fixtures perfectly.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this SKU lacks a magnet, so it cannot accept position sensors. If high-temperature operation is needed, a Viton H seal option raises the operating range to 0-150 C.

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).
Provides the massive 15708 N push at 0.5 MPa needed to eject large formed parts from heavy industrial presses over a 1500 mm travel distance.
Drives oversized diverter arms on high-capacity bulk material conveyors, utilizing the 50 mm adjustable cushions to decelerate heavy loads at stroke ends.
To replace the SI200X1500, order the SAI200X1500 and verify your ISO 15552 mounting interface, M36x2 rod thread, G3/4 port, and 1500 mm stroke. Because this plain unit has no magnet, it cannot support legacy CS1-B/DS1-B sensors. If you need to downsize, the 160 mm bore offers 10053 N push at 0.5 MPa; if sizing up, consider external solutions. A standard cylinder does not hold load on air loss—the cushion only decelerates—so for holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Finally, at 1500 mm, the 40 mm rod is highly susceptible to bending; always use external guides to prevent side loads.
Replacement checklist
Yes, the SI200X1500 is discontinued. The direct replacement is the SAI200X1500. It features the same ISO 15552 mounting interface, 200 mm bore, 1500 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
The 200 mm bore delivers 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. The G3/4 port and M36x2 rod thread are fixed by the bore.
