This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X230TC, 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 SI160X230TC
The AirTAC SI160 Standard Cylinder SI160X230TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 230mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X230TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X230TC
The AirTAC SI160X230TC is a discontinued double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a push force of 10053 N at 0.5 MPa. It features a 160mm bore, 230mm stroke, and a G3/4 air port. The direct replacement is the SAI160X230TC, which shares identical ISO 15552 mounting interface dimensions, output force, and TC trunnion mount.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S), so it cannot accept position sensors.

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

Where the Airtac SI160 Standard Cylinder SI160X230TC Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 10053 N of push force at 0.5 MPa to deform thick plate stock.
Mold Clamping Stations
Secures heavy injection molds via the TC trunnion mount, handling high kinetic energy with 50mm cushions.
Replacing the Airtac SI160 Standard Cylinder SI160X230TC with the SAI160X230TC
To replace the discontinued SI160X230TC, order the SAI160X230TC. Verify your existing fixture's ISO 15552 TC trunnion interface, 160mm bore, 230mm stroke, and G3/4 port. The SAI family also offers the SAIL air-released lock and BSAI clamp-lock variants if your application requires load holding, as a standard cylinder drifts without live air and its cushion only decelerates. If downsizing, a 125mm bore yields 6136 N push at 0.5 MPa; if upsizing, a 200mm bore provides 15708 N. For any stroke at or above 300mm, incorporate external guide rails to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X230TC
- ✓ 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 SI160X230TC FAQ
Yes, the SI160X230TC is discontinued. The direct replacement is the SAI160X230TC. It features the same ISO 15552 mounting interface, 160mm bore, 230mm stroke, G3/4 port, and force ratings, fitting existing TC trunnion fixtures perfectly.
The 160mm bore delivers a push of 10053 N and pull of 9425 N at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a maximum theoretical force of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
