This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X80H, 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 SI160X80H
The AirTAC SI160 Standard Cylinder SI160X80H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X80H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X80H
The AirTAC SI160X80H is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke and a high-temperature Viton H seal. It delivers 10053 N push force at 0.5 MPa through its G3/4 port. The direct replacement is the SAI160X80H, which shares the same ISO 15552 mounting interface, bore, stroke, force, and port.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks a magnet (-S) and cannot support legacy CS1-B/DS1-B sensors.

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 SI160X80H Is Used
Heavy Stamping Press
Drives heavy tooling in automated stamping lines, utilizing the 10053 N push force at 0.5 MPa to form thick metal components reliably.
High-Temperature Molding
Actuates large mold halves in hot environments up to 150 C, leveraging the Viton H seals to maintain structural integrity without degrading.
Replacing the Airtac SI160 Standard Cylinder SI160X80H with the SAI160X80H
To replace the SI160X80H, order the SAI160X80H. Confirm the ISO 15552 mounting interface, the 160 mm bore, the 80 mm stroke, the G3/4 port, and your Viton H high-temperature seal requirement (0-150 C). Because this SKU lacks a magnet, it cannot accept position sensors; if sensing is needed, specify an SAI model with the S suffix for current AirTAC switches. A plain cylinder does not hold load on air loss—the cushion only decelerates—so for load holding, consider the SAIL lock, BSAI clamp-lock variant, or an external pilot check valve. If sizing up or down, neighbouring bores (125 mm or 200 mm) offer different force classes, but the 160 mm bore uniquely provides a 14074 N push at 0.7 MPa. For any stroke over 300 mm, add external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X80H
- ✓ 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 SI160X80H FAQ
Yes, the AirTAC SI160X80H is discontinued and end-of-life. The direct replacement is the SAI160X80H. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 80 mm stroke, 10053 N force, G3/4 port, and mounting interface. You can order the SAI160X80H as a direct fit for existing fixtures.
This double-acting cylinder features a G3/4 air port and a 40 mm piston rod. The thrust ratings are: 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 force of 2050 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
