This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X60FB, 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 SI160X60FB
The AirTAC Airtac SI160 Standard Cylinder SI160X60FB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X60FB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X60FB
The AirTAC SI160X60FB is a discontinued double-acting ISO 15552 profile cylinder with an FB flange mount, delivering a push force of 10053 N at 0.5 MPa. Because this legacy series is end-of-life, AirTAC supplies the SAI160X60FB as the direct replacement. It preserves the exact 160mm bore, 60mm stroke, G3/4 port, M36x2 rod thread and 50mm cushions, dropping straight into your existing fixtures.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. As this SKU lacks the -S magnet, it cannot accept a CS1-B or DS1-B sensor. If high-temperature operation is needed, Viton H seals raise the range to 150 C.

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 SI160X60FB Is Used
Heavy Press Operations
Drives high-tonnage pressing and forming tasks using its 14074 N push force at 0.7 MPa to seat heavy components securely.
Pallet Lift Gates
Actuates robust lifting gates on conveyors, moving loads safely within the 512kg vertical lift margin calculated at 0.5 MPa.
Mold Clamping Stations
Holds large injection molds via the FB flange mount, utilizing the 50mm adjustable air cushions to decelerate the 40mm rod smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160X60FB with the SAI160X60FB
To replace the SI160X60FB, order the SAI160X60FB and verify the ISO 15552 FB flange interface, 160mm bore, 60mm stroke and G3/4 port. If you need to re-size, neighbouring bores offer different force classes, but this 160mm bore yields 10053 N push at 0.5 MPa. Note that a plain double-acting cylinder drifts on air loss; the 50mm cushions only decelerate near stroke end. For load holding, use an external pilot check valve, a rod lock, or the SAI family's SAIL or BSAI lock variants. Since the stroke is under 300mm, rod-bending side loads are minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X60FB
- ✓ 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 SI160X60FB FAQ
Yes, the SI160X60FB is discontinued. The direct replacement is the SAI160X60FB. It is dimensionally interchangeable per ISO 15552, maintaining the same 160mm bore, 60mm stroke, FB mount, G3/4 port and output force.
This double-acting cylinder uses a G3/4 air port. 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 maximum of 2050 kgf at 1.0 MPa.
