This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X395TC, 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 SI160X395TC
The AirTAC SI160 Standard Cylinder SI160X395TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 395mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X395TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X395TC
The AirTAC SI160X395TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore, 395 mm stroke, and TC trunnion mount. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI160X395TC. This direct upgrade shares the exact ISO 15552 mounting interface, bore, and stroke.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This no-magnet SKU cannot take a sensor, unlike legacy CS1-B/DS1-B setups. For high heat, Viton H seals raise the limit to 150 C.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X395TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X395TC Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large metal castings during machining operations.
Pallet Diverting
Uses the TC trunnion mount to pivot heavy pallets smoothly on high-throughput packaging lines.
Replacing the Airtac SI160 Standard Cylinder SI160X395TC with the SAI160X395TC
To replace the SI160X395TC, order the SAI160X395TC. Confirm the ISO 15552 TC trunnion interface, 160 mm bore, 395 mm stroke, G3/4 port (PT/G/NPT), and M36x2 rod thread. This SKU lacks a magnet (-S), so it cannot accept position sensors. For sizing both ways: a 125 mm bore yields 6136 N [email protected], while a 200 mm bore yields 15708 N. At 395 mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X395TC
- ✓ 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 SI160X395TC FAQ
Yes, the SI160X395TC is discontinued. The direct replacement is the SAI160X395TC. It shares the same ISO 15552 TC mounting interface, 160 mm bore, 395 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical max is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, with a 50 mm adjustable air cushion at both ends.
