This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX190, 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 SI160BX190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX190, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160BX190 is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 190mm stroke. Delivering 10053N push force at 0.5MPa, it uses a G3/4 port and M36x2 rod thread. The direct replacement is SAI160BX190, matching the exact ISO 15552 mounting interface, force, and stroke.
This SKU lacks a magnet and cannot take a sensor. The SUS304 stainless rod resists corrosion. The SAI upgrade features two Y-shaped piston seals for low start-up pressure.

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 10053N of thrust at 0.5MPa, utilizing the 190mm stroke for deep draw operations.
Indexes heavy loaded pallets on conveyors where the 160mm bore provides the necessary force to overcome static friction and move substantial weights.
Secures large fabricated components during welding or machining, using the robust SUS304 stainless rod for corrosion resistance in harsh environments.
To replace the SI160BX190, order the SAI160BX190. Confirm the ISO 15552 mounting interface, 190mm stroke, and G3/4 port. This SKU has no magnet (-S), so it cannot accept a CS1-B/DS1-B sensor; order a magnet-equipped SAI if position detection is needed. Neighbouring bores are 125mm (6136N @0.5MPa) and 200mm (15708N @0.5MPa). The 190mm stroke is under the 300mm side-load threshold, but always guide the load to prevent rod bending. For load holding on air loss, use an external rod lock or pilot check valve, or specify the SAIL/BSAI lock variant, as cushions only decelerate.
Replacement checklist
Yes, the AirTAC SI160BX190 is discontinued. The direct replacement is the SAI160BX190. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 190mm stroke, 10053N force, G3/4 port, and mounting interface.
The 160mm bore uses a G3/4 port. Force ratings are: 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max of 2050kgf at 1.0MPa. Speed is 30-500mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI160BX190 replacement — usually within 7-8 hours.
