This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX195S, 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 SI160BX195S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 195mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX195S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160BX195S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 195mm stroke. It delivers 10053N push and 9425N pull at 0.5MPa via a G3/4 port. The direct replacement is the SAI160BX195S, matching the interface, stroke and force exactly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This SI unit has a SUS304 stainless rod (-B) and a piston magnet (-S) for CS1-B/DS1-B legacy sensors. The 195mm stroke is nonstandard. Note that plain cylinders drift without live air; use an external rod lock or the SAIL/BSAI lock variant for load holding. Viton H seals raise the temperature range to 150C.

The SAI160BX195S 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 forming dies and heavy-duty presses requiring up to 14074N of push force at 0.7MPa with stable ISO 15552 mounting.
Operates in humid or washdown environments using the SUS304 piston rod option to prevent corrosion while moving heavy jigs.
To replace the SI160BX195S, order the SAI160BX195S. Confirm the ISO 15552 mounting interface, 160mm bore, 195mm stroke, G3/4 port, and the -B SUS304 rod. The -S magnet means it accepts CS1-B/DS1-B switches, though the SAI uses current AirTAC sensors. Because the 195mm stroke is nonstandard, verify lead times. For sizing, neighboring bores are 125mm (6136N push @0.5MPa) and 200mm (15708N push). Since the stroke is under 300mm, severe rod-bending side loads are less critical than on long strokes, but always guide the load. A plain cylinder does not hold load on air loss; the cushion only decelerates. For secure holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
Yes, the AirTAC SI160BX195S is discontinued. The direct replacement is the SAI160BX195S. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 195mm stroke, 10053N force, G3/4 port, and mounting accessories.
At 0.5MPa it provides 10053N push and 9425N pull. At 0.7MPa push is 14074N, and at 0.9MPa it is 18095N. The theoretical max force is 2050kgf at 1.0MPa. Operating speed is 30-500mm/s, and it uses a G3/4 port.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI160BX195S replacement — usually within 7-8 hours.
