This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX100S, 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 SI160BX100S
The AirTAC SI160 Standard Cylinder SI160BX100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX100S
The AirTAC SI160BX100S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 100 mm stroke. It delivers a robust 10053 N push force at 0.5 MPa through its G3/4 port. The direct replacement is the SAI160BX100S, which matches the exact ISO 15552 mounting interface, bore, stroke, force, and port size for immediate fixture compatibility.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This specific SKU includes a SUS304 stainless piston rod (-B) for corrosion resistance and a magnet (-S) for 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 SI160BX100S Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large steel fabrications during heavy-duty machining or welding operations.
Injection Mold Ejection
Uses the 100 mm stroke and SUS304 rod to eject dense molded components, resisting moisture and plant corrosion.
Replacing the Airtac SI160 Standard Cylinder SI160BX100S with the SAI160BX100S
To replace this SI160BX100S, order the SAI160X100SB to retain the SUS304 rod and magnet. Confirm the ISO 15552 mounting interface (foot, flange, or trunnion), the G3/4 port, and the 100 mm stroke. Sizing both ways: this 160 mm bore yields 10053 N push at 0.5 MPa; if less force is needed, a 125 mm bore offers 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end. For load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve. The SAI family also adds the SAIF valve option for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX100S
- ✓ 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 SI160BX100S FAQ
Yes, the SI160BX100S is discontinued. The direct replacement is the SAI160BX100S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 100 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
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 max is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s. The G3/4 port and 50 mm cushions manage the flow.
