This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX130S, 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 SI160BX130S
The AirTAC SI160 Standard Cylinder SI160BX130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 130mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX130S
The AirTAC SI160BX130S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 130mm stroke. Delivering 10053N push force at 0.5MPa via a G3/4 port, it is replaced by the SAI160BX130S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors, and the -B rod is SUS304 stainless steel.

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 SAI160BX130S 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 SI160BX130S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping and forming presses requiring 10053N push force at 0.5MPa with stable 130mm travel.
Large Clamp Actuation
Actuates robust clamping mechanisms in fabrication cells, utilising the SUS304 stainless rod for corrosion resistance.
Replacing the Airtac SI160 Standard Cylinder SI160BX130S with the SAI160BX130S
To replace this SI160BX130S, order the SAI160BX130S. Confirm the ISO 15552 mounting interface, 130mm stroke, G3/4 port (PT/G/NPT thread options), mounting accessory, and the -S magnet for CS1-B/DS1-B switches. The -B code specifies the SUS304 stainless piston rod for corrosion resistance, versus the default carbon steel rod. Sizing both ways: this 160mm bore yields 10053N push at 0.5MPa; a neighbouring 125mm bore yields 6136N, while a 200mm bore yields 15708N. For load holding, note a plain cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX130S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
