This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1380S, 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 SI160X1380S
The AirTAC SI160 Standard Cylinder SI160X1380S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1380mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1380S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1380S
The AirTAC SI160X1380S is a discontinued double-acting ISO 15552 profile cylinder. Built for heavy-duty tasks, it delivers 10053 N push force at 0.5 MPa through a 160 mm bore and 1380 mm stroke. AirTAC replaced this legacy unit with the SAI160X1380S direct replacement, retaining the identical interface, G3/4 port, and M36x2 rod thread.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors, while Viton H seals can raise the operating ceiling 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 SI160X1380S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping presses requiring 10053 N of push force at 0.5 MPa to form thick metal components reliably.
Pallet Diversion
Actuates robust pallet diversion gates on high-capacity conveyor lines, utilizing the 1380 mm stroke to clear wide loads.
Replacing the Airtac SI160 Standard Cylinder SI160X1380S with the SAI160X1380S
To replace the SI160X1380S, order the SAI160X1380S direct, verifying the ISO 15552 mounting interface, 1380 mm stroke, G3/4 port, and M36x2 thread. If downsizing, a 125 mm bore yields 6136 N at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N. Note that a plain cylinder drifts on air loss since the 50 mm adjustable cushion only decelerates near stroke end. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variant. Because the 1380 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1380S
- ✓ 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 SI160X1380S FAQ
Yes, the SI160X1380S is discontinued. The direct replacement is the SAI160X1380S, which shares the identical ISO 15552 mounting interface, 160 mm bore, 1380 mm stroke, output force, and G3/4 port. It fits directly into existing fixtures.
This double-acting cylinder features a G3/4 port and delivers 10053 N push and 9425 N pull at 0.5 MPa. At 0.7 MPa the push is 14074 N, and the theoretical maximum force is 2050 kgf at 1.0 MPa.
