This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X120TC, 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 SI160X120TC
The AirTAC SI160 Standard Cylinder SI160X120TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 120mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X120TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X120TC
The AirTAC SI160X120TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 120 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160X120TC, which shares the exact ISO 15552 mounting interface, TC trunnion, and output force.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure, and the family adds SAIL and BSAI lock variants the SI lacked.

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 SI160X120TC Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring 10053 N of push force at 0.5 MPa with robust TC trunnion mounting.
Large Mold Handling
Shifts heavy industrial molds on production lines, utilizing the 120 mm stroke to index substantial loads safely.
Industrial Clamp Systems
Secures oversized fabricated components during welding or machining, benefiting from the 160 mm bore's 9425 N pull force.
Replacing the Airtac SI160 Standard Cylinder SI160X120TC with the SAI160X120TC
To replace this SI160X120TC, order the SAI160X120TC and confirm the ISO 15552 TC trunnion mount, 120 mm stroke, and G3/4 port. This non-magnetic SKU cannot hold a position switch; order an -S magnet if sensing is needed. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding. If downsizing, a 125 mm bore yields 6136 N at 0.5 MPa; if upsizing, a 200 mm bore yields 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X120TC
- ✓ 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 SI160X120TC FAQ
Yes, the AirTAC SI160X120TC is discontinued. The direct replacement is the SAI160X120TC. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 120 mm stroke, TC mounting, and G3/4 port for a direct fixture fit.
The 160 mm bore uses a G3/4 port and a 40 mm rod. It generates 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, and a theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
