This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X510, 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 SI160X510
The AirTAC SI160 Standard Cylinder SI160X510 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 510mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X510, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X510
The AirTAC SI160X510 is a discontinued double-acting ISO 15552 profile cylinder. It delivers 10053 N push force at 0.5 MPa through a 160 mm bore and 510 mm stroke. The direct replacement is the SAI160X510, matching the exact interface, port, and force.
This SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Note this SKU lacks a magnet and cannot take a sensor; legacy CS1-B/DS1-B switches required the -S option.

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 SAI160X510 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 SI160X510 Is Used
Heavy Press Systems
Drives large industrial presses requiring up to 14074 N push force at 0.7 MPa for metal forming and stamping operations.
Large Mold Handling
Actuates 510 mm stroke movements to position heavy injection molds, relying on external guides to prevent rod bending.
Replacing the Airtac SI160 Standard Cylinder SI160X510 with the SAI160X510
To replace the SI160X510, order the SAI160X510. Verify the ISO 15552 mounting interface, 510 mm stroke, G3/4 port, and M36x2 rod thread. Because this SKU lacks the -S magnet, it cannot accept position sensors. For sizing, the neighboring 200 mm bore yields 15708 N push at 0.5 MPa, while the 125 mm bore yields 6136 N. At 510 mm stroke, use external guides to prevent rod bending and side loads. 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 → SAI160X510
- ✓ 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 SI160X510 FAQ
Yes, the SI160X510 is discontinued. The direct replacement is the SAI160X510. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 510 mm stroke, G3/4 port, and mounting accessories.
It features a G3/4 air port. The force output is 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 maximum of 2050 kgf at 1.0 MPa.
