This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X160TC, 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 SI160X160TC
The AirTAC SI160 Standard Cylinder SI160X160TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X160TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X160TC
The AirTAC SI160X160TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 160 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X160TC, sharing the exact TC trunnion mounting, M36x2 thread, and dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Without a magnet, this SKU cannot take a sensor. For high heat, Viton H seals raise limits 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 SAI160X160TC 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 SI160X160TC Is Used
Heavy Stamping Press
Drives large heavy-duty stamping and forming presses requiring up to 14074 N of thrust at 0.7 MPa.
Pallet Lift Station
Lifts loaded pallets in automated distribution hubs, safely handling vertical loads around 512 kg.
Mold Clamping Fixture
Secures large injection molds using the rigid TC trunnion mount to handle high lateral stability needs.
Replacing the Airtac SI160 Standard Cylinder SI160X160TC with the SAI160X160TC
To replace the SI160X160TC, order the SAI160X160TC to retain the ISO 15552 TC trunnion mount, 160 mm stroke, and G3/4 port. This non-magnet SKU cannot accept CS1-B/DS1-B sensors. If sizing down, the 125 mm bore yields 6136 N at 0.5 MPa; if sizing up, the 200 mm bore gives 15708 N. The cushion only decelerates; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants. At 160 mm stroke, rod bending is minimal, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X160TC
- ✓ 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 SI160X160TC FAQ
Yes, the SI160X160TC is discontinued. The direct replacement is the SAI160X160TC. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 160 mm stroke, G3/4 port, and TC trunnion mounting.
This double-acting cylinder uses a G3/4 port. It generates 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
