This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X190STC, 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 SI160X190STC
The AirTAC SI160 Standard Cylinder SI160X190STC 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 SAI160X190STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X190STC
The AirTAC SI160X190STC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 190 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X190STC, retaining the same TC trunnion mount, M36x2 thread, and dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. For high heat, Viton H seals raise limits to 150 C. The -S magnet works with CS1-B/DS1-B sensors.

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 SI160X190STC Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to securely hold large metal castings during machining operations.
Mold Ejection Systems
Drives robust ejection pins in injection molding lines using the TC trunnion for pivot alignment.
Replacing the Airtac SI160 Standard Cylinder SI160X190STC with the SAI160X190STC
To replace the SI160X190STC, order the SAI160X190STC. Verify the ISO 15552 TC trunnion interface, 190 mm stroke, G3/4 port, and -S magnet. At 0.5 MPa it pushes 10053 N; the neighboring 125 mm bore yields 6136 N, while the 200 mm bore gives 15708 N. A plain cylinder drifts without live air; use an external rod lock or pilot check valve for load holding, or specify the SAIL/BSAI lock variant. At 190 mm, side-load risk is low, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X190STC
- ✓ 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 SI160X190STC FAQ
Yes, the SI160X190STC is discontinued. The direct replacement is the SAI160X190STC. It shares the identical ISO 15552 mounting interface, 160 mm bore, 190 mm stroke, G3/4 port, and TC mount, fitting existing fixtures perfectly.
This double-acting cylinder operates at 30-500 mm/s. Force outputs 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; with a theoretical max of 2050 kgf at 1.0 MPa.
