This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX190S, 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 SI160AX190S
The AirTAC SI160 Standard Cylinder SI160AX190S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX190S
The AirTAC SI160AX190S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 190 mm stroke. It delivers a push force of 10053 N at 0.5 MPa and uses a G3/4 air port. The direct replacement is the SAI160AX190S, which maintains the same interface, force, and port size.
This SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SI160AX190S includes a SUS420J2 stainless steel rod and a magnet for CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160AX190S Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring up to 10053 N of push force at 0.5 MPa.
Mold Handling
Shifts large injection molds on production lines using the robust 40 mm SUS420J2 stainless piston rod.
Replacing the Airtac SI160 Standard Cylinder SI160AX190S with the SAI160AX190S
To replace the SI160AX190S, order the SAI160AX190S. Confirm the ISO 15552 mounting interface, 190 mm stroke, G3/4 port, and mounting accessory. The SAI is a direct. If downsizing, a 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, a 200 mm bore yields 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The -A suffix denotes the SUS420J2 rod, and -S means a magnet for CS1-B/DS1-B switches (SAI uses current AirTAC switches).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX190S
- ✓ 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 SI160AX190S FAQ
Yes, the SI160AX190S is discontinued. The direct replacement is the SAI160AX190S. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 190 mm stroke, 10053 N force, and G3/4 port.
The SI160AX190S delivers a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical max force is 2050 kgf at 1.0 MPa, with an operating speed of 30-500 mm/s.
