This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX105, 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 SI160AX105
The AirTAC Airtac SI160 Standard Cylinder SI160AX105 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 105mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX105, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX105
The AirTAC SI160AX105 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 105 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160AX105, which matches the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This SKU lacks a magnet, so it cannot take CS1-B/DS1-B sensors. It has an SUS420J2 stainless rod (option A).

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 SAI160AX105 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 SI160AX105 Is Used
Heavy Press Forming
Generates 14074 N of push force at 0.7 MPa to form thick metal plates and stamp heavy industrial components.
Injection Mold Clamping
Holds large mold halves securely in place during high-pressure plastic injection molding cycles.
Replacing the Airtac SI160 Standard Cylinder SI160AX105 with the SAI160AX105
To replace the SI160AX105, order the SAI160AX105. Verify the ISO 15552 mounting fixture, 105 mm stroke, G3/4 port, and SUS420J2 rod. Because this non-magnet SKU cannot accept position sensors, add external limit switches if needed. For sizing, the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. Note that a plain cylinder drifts on air loss; the 50 mm cushions only decelerate. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants. The Viton H seal option raises heat resistance to 150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX105
- ✓ 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 SI160AX105 FAQ
Yes, the SI160AX105 is discontinued. The direct replacement is the SAI160AX105. It shares the identical ISO 15552 mounting interface, 160 mm bore, 105 mm stroke, output force, G3/4 port, and accessories, fitting directly into existing fixtures.
The cylinder operates at 30-500 mm/s. At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical maximum force is 2050 kgf at 1.0 MPa.
