This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X710S, 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 SI160 Standard Cylinder SI160X710S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 710mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X710S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160X710S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 710 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X710S, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force, and port.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X710S 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).
Applies the 14074 N push at 0.7 MPa for heavy-duty metal pressing and forming operations requiring sustained high force.
Drives large 710 mm vertical lifting gates on heavy palletizers, moving loads up to the 512 kg vertical lift limit safely.
Actuates large heavy-duty diverter arms on bulk material conveyors, utilizing the robust 40 mm piston rod.
To replace the SI160X710S, order the SAI160X710S direct, confirming the ISO 15552 interface, 710 mm stroke, G3/4 port, and M36x2 rod thread. Because this is a 710 mm stroke, use external guides to prevent rod bending and side-load damage. Sizing both ways: a 200 mm bore offers more force, while a 125 mm bore provides 6136 N push at 0.5 MPa. The air cushion only decelerates; it does not hold load on air loss, so use an external rod lock or pilot check valve for holding. The SAI family includes the SAIL air-released lock and BSAI clamp-lock variants if integrated holding is required.
Replacement checklist
Yes, the SI160X710S is discontinued. The direct replacement is the SAI160X710S. It shares the same ISO 15552 mounting interface, 160 mm bore, 710 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 160 mm bore delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s. It uses a G3/4 port and M36x2 rod thread.
