This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX60S, 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 SI160BX60S
The AirTAC SI160 Standard Cylinder SI160BX60S 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 SAI160BX60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX60S
The AirTAC SI160BX60S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 60 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a SUS304 stainless piston rod, an integrated magnet for CS1-B/DS1-B sensors, and a G3/4 air port. AirTAC replaced this EOL unit with the SAI160BX60S, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force, and port.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. For load holding, note that a plain cylinder drifts without live air; the cushion only decelerates. Use an external rod lock or pilot check valve, or step up to the SAIL or BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160BX60S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI160BX60S 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 SI160BX60S Is Used
Heavy Press Clamping
Generates 10053 N at 0.5 MPa to secure heavy metal fabrications during machining or welding operations.
Stamping Ejection
Uses the 60 mm stroke and SUS304 rod to eject formed parts from humid or washdown stamping dies.
Replacing the Airtac SI160 Standard Cylinder SI160BX60S with the SAI160BX60S
To replace the SI160BX60S, order the SAI160BX60S. Confirm the ISO 15552 mounting interface, 60 mm stroke, G3/4 port, and your mounting accessory (LB, FA, CA, TC). The -S magnet enables CS1-B/DS1-B sensors, though the SAI uses current AirTAC switches. The -B rod is SUS304 stainless steel. If sizing up or down, neighboring bores are 125 mm and 200 mm; at 0.5 MPa this 160 mm bore yields 10053 N push and 9425 N pull. For any load requiring holding on air loss, add a pilot check valve or specify the SAIL or BSAI lock variant, as standard cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX60S
- ✓ 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 SI160BX60S FAQ
Yes, the SI160BX60S is discontinued. The direct replacement is the SAI160BX60S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 60 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 160 mm bore provides 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 maximum theoretical force of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, with a 50 mm adjustable cushion at each end.
