This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX475, 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 SI160AX475
The AirTAC Airtac SI160 Standard Cylinder SI160AX475 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 475mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX475, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX475
The AirTAC SI160AX475 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 475 mm stroke. It delivers a thrust of 10053 N at 0.5 MPa. AirTAC replaced this EOL unit with the SAI160AX475. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke, output force, G3/4 port and accessories, fitting existing fixtures perfectly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This SI160AX475 variant uses a SUS420J2 stainless steel rod (option A) for corrosion resistance. It lacks a magnet, so it cannot take a sensor.

Where the Airtac SI160 Standard Cylinder SI160AX475 Is Used
Heavy Machinery Forming
Drives large forming presses and heavy-duty industrial machinery requiring sustained high thrust over a 475 mm extension.
Automated Assembly Actuation
Shifts massive tooling platens and heavy clamping fixtures in automated automotive assembly lines with stable, high-force motion.
Replacing the Airtac SI160 Standard Cylinder SI160AX475 with the SAI160AX475
To replace the SI160AX475, order the SAI160AX475. Confirm the ISO 15552 mounting interface, 475 mm stroke, G3/4 port, and M36x2 rod thread. Because this SKU lacks a magnet (-S), it cannot accept position sensors; if sensing is needed, order an SAI equivalent with the S suffix. The SUS420J2 stainless rod (A) is standard here, differing from the default carbon steel. For loads needing holding on air loss, a plain cylinder drifts; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. With a 475 mm stroke, prevent rod bending by guiding the load externally. If downsizing, a 125 mm bore gives 6136 N push at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX475
- ✓ 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 SI160AX475 FAQ
Yes, the SI160AX475 is discontinued. The direct replacement is the SAI160AX475. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 475 mm stroke, output force, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 port. It delivers a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa the push force is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical maximum force is 2050 kgf at 1.0 MPa.
