This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X700CB, 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 Airtac SI160 Standard Cylinder SI160X700CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X700CB, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160X700CB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 700 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a 40 mm rod, M36x2 thread, and a G3/4 port. The direct replacement is the SAI160X700CB, which shares the exact same ISO 15552 mounting interface, CB clevis mount, and output force.
This SKU lacks the -S magnet option, meaning it cannot accept position sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure, and adds SAIL, SAIF, and BSAI lock variants the SI lacked.

The SAI160X700CB 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 presses and forming fixtures requiring up to 10053 N of thrust at 0.5 MPa, utilizing the 160 mm bore for substantial metal deformation tasks.
Actuates heavy-duty diverter arms on high-capacity bulk conveyors, relying on the 700 mm stroke to clear wide product flows completely.
To replace the SI160X700CB, order the SAI160X700CB and confirm the ISO 15552 CB clevis mounting, 700 mm stroke, and G3/4 port. Because this unit has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify a magnet on the new SAI. When sizing, neighboring bores offer different forces: the 125 mm bore provides 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Finally, at 700 mm stroke, prevent rod bending by guiding the load externally to avoid side-loading.
Replacement checklist
Yes, the SI160X700CB is discontinued. The direct replacement is the SAI160X700CB. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 700 mm stroke, CB clevis mount, G3/4 port, and output force.
The G3/4 port supplies a 40 mm rod. Force output is 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.
