This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX160, 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 SI160BX160
The AirTAC SI160 Standard Cylinder SI160BX160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX160
The AirTAC SI160BX160 is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 160mm stroke. It delivers 10053 N push and 9425 N pull at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160BX160, which matches the exact interface, force, and mounting hardware.
This SKU features a SUS304 stainless piston rod (-B) but lacks a magnet, so it cannot accept CS1-B or DS1-B sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure.

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 SI160BX160 Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large steel plates during machining or welding operations.
Injection Mold Ejection
Uses the SUS304 stainless rod to resist moisture while pushing heavy molded parts out of industrial tooling.
Replacing the Airtac SI160 Standard Cylinder SI160BX160 with the SAI160BX160
To replace the SI160BX160, order the SAI160BX160. Verify the ISO 15552 mounting interface, 160mm stroke, and G3/4 port. Because this SKU lacks an -S magnet, it cannot support position sensing; if switches are needed, specify a magnet on the new unit. The 160mm bore yields 10053 N push at 0.5 MPa; if less force is acceptable, a 125mm bore provides 6136 N. For load holding, note that a standard cylinder drifts on air loss—the cushion only decelerates. Use an external pilot check valve or the SAIL/BSAI lock variants. The SUS304 rod offers corrosion resistance, and a Viton H seal raises operating temperature to 150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX160
- ✓ 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 SI160BX160 FAQ
Yes, the SI160BX160 is discontinued. The direct replacement is the SAI160BX160. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 160mm stroke, 10053 N force, and G3/4 port.
It 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, at 0.9 MPa it is 18095 N, and the theoretical max is 2050 kgf at 1.0 MPa.
