This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X470S, 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 SI160X470S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 470mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X470S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160X470S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 470mm stroke. Delivering 10053N push force at 0.5MPa via a G3/4 port, it is replaced by the SAI160X470S. This direct upgrade matches the exact mounting interface, bore, stroke, force and accessories.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants the SI lacked. This -S SKU uses CS1-B/DS1-B sensors.

| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X470S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 10053N push force needed to eject heavy molded parts or stampings from large industrial presses.
Drives 470mm downstroke motions in heavy-duty assembly stations, forming, or riveting applications requiring massive force.
Handles the substantial 512kg vertical lift capacity to position heavy structural components or pallets in automated warehouses.
To replace the SI160X470S, order the SAI160X470S. Verify the ISO 15552 mounting interface, 470mm stroke, M36x2 rod thread, G3/4 port, and your mounting accessory (LB, FA, TC, etc.). The -S suffix means a magnet for CS1-B/DS1-B switches; the SAI uses current AirTAC switches. Sizing both ways: the 125mm bore yields 6136N push at 0.5MPa, while the 200mm bore yields 15708N. At 470mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts without live air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
Yes, the SI160X470S is discontinued. The direct replacement is the SAI160X470S. It is dimensionally interchangeable per ISO 15552, matching the 160mm bore, 470mm stroke, G3/4 port, and mounting interface, but features an upgraded two Y-shaped element piston seal.
At 0.5MPa, push force is 10053N and pull is 9425N. At 0.7MPa push is 14074N, and 18095N at 0.9MPa. The theoretical max is 2050kgf at 1.0MPa. Speed is 30-500mm/s. The air cushion is 50mm, and the G3/4 port handles the required air volume.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI160X470S replacement — usually within 7-8 hours.
