This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X890, 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.
Airtac SI160 Standard Cylinder SI160X890
The AirTAC SI160 Standard Cylinder SI160X890 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 890mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X890, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X890
The AirTAC SI160X890 is a discontinued double-acting ISO 15552 profile cylinder with an 890 mm stroke, delivering 10053 N push force at 0.5 MPa through its G3/4 port. AirTAC replaced this legacy unit with the SAI160X890, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, and output. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
This non-magnet SKU cannot accept a position sensor. If high-temperature operation is needed, Viton H seals raise the range to 0-150 C.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |

Where the Airtac SI160 Standard Cylinder SI160X890 Is Used
Heavy Press Systems
Drives large stamping and forming presses requiring up to 14074 N thrust at 0.7 MPa over a long 890 mm travel distance.
Bulk Material Diversion
Actuates large-scale heavy-duty diverters on assembly lines, utilizing the 50 mm adjustable cushions to brake high inertia smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160X890 with the SAI160X890
To replace the SI160X890, order the SAI160X890, confirming the ISO 15552 mounting interface, 160 mm bore, 890 mm stroke, and G3/4 port. Because this 890 mm stroke is long, use external guides to prevent rod bending and side-load damage. Sizing down, the 125 mm bore yields 6136 N push at 0.5 MPa; sizing up, the 200 mm bore yields 15708 N. 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 variants. This non-S model cannot take CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X890
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X890 FAQ
Yes, the SI160X890 is discontinued. The direct replacement is the AirTAC SAI160X890. It shares the identical ISO 15552 mounting interface, 160 mm bore, 890 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
This double-acting cylinder uses a G3/4 air port. It 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 maximum of 2050 kgf at 1.0 MPa.
