This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X190, 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 SI160X190
The AirTAC SI160 Standard Cylinder SI160X190 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 SAI160X190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X190
The AirTAC SI160X190 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 190 mm stroke, delivering 10053 N of push force at 0.5 MPa. It features a 40 mm carbon steel rod, M36x2 thread, and a G3/4 air port. Because this legacy unit lacks a magnet (-S), it cannot accept position sensors. AirTAC replaced it with the SAI160X190, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, stroke, and port.
The SAI160X190 introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also adds lock variants (SAIL, BSAI) absent in the SI line, and a Viton H seal option raises operating temperature to 150 C.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160X190 Is Used
Heavy Press Operations
Drives large forming and stamping presses requiring up to 18095 N of thrust at 0.9 MPa, utilizing the 50 mm adjustable cushion to decelerate massive inertia smoothly.
Automated Assembly Forming
Provides the robust linear motion needed for riveting heavy structural components, taking advantage of the 160 mm bore's 14074 N output at 0.7 MPa.
Replacing the Airtac SI160 Standard Cylinder SI160X190 with the SAI160X190
To replace the SI160X190, order the SAI160X190, confirming the ISO 15552 mounting interface, 190 mm stroke, and G3/4 port (PT/G/NPT). Verify your mounting accessory (LB, FA, TC) and note this non-magnetic SKU cannot support CS1-B/DS1-B sensors. For sizing both ways: a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for held loads. At 190 mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X190
- ✓ 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 SI160X190 FAQ
Yes, the SI160X190 is discontinued. The direct replacement is the SAI160X190. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 190 mm stroke, output force, G3/4 port, and mounting interface to fit existing fixtures directly.
This double-acting cylinder has a G3/4 air port. The thrust ratings are: 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. Operating speed is 30-500 mm/s.
