This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX35, 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 SI160AX35
The AirTAC SI160 Standard Cylinder SI160AX35 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 35mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX35, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX35
The AirTAC SI160AX35 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 35 mm stroke. Delivering 10053 N push force at 0.5 MPa through a G3/4 port, it is replaced by the SAI160AX35. This direct upgrade matches the original ISO 15552 mounting interface, bore, stroke, force, port and accessories. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific -A variant uses a SUS420J2 stainless steel piston rod for corrosion resistance. With no -S suffix, this SKU cannot take a magnetic sensor.
The SAI family expands on the legacy SI line by adding variants like the SAIL air-released lock, SAIF built-in 4M valve, and BSAI clamp-lock. For high-temperature environments, a Viton H seal option raises the operating range to 0-150 C. Note that a plain cylinder does not hold load on air loss; the 50 mm adjustable air cushions only decelerate near stroke end. For load holding, consider an external pilot check valve or the SAIL/BSAI lock variants.

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 SI160AX35 Is Used
Heavy Stamping
Generates 14074 N at 0.7 MPa to drive heavy-duty stamping and forming presses requiring high impact force.
Pallet Diverting
Shifts loaded pallets on conveyors using the 9425 N pull force at 0.5 MPa with a robust 40 mm rod.
Injection Molding
Actuates large mold cores and heavy platens where the SUS420J2 stainless rod resists environmental moisture.
Replacing the Airtac SI160 Standard Cylinder SI160AX35 with the SAI160AX35
To replace the discontinued SI160AX35, order the SAI160AX35. Confirm the ISO 15552 mounting interface, 160 mm bore, 35 mm stroke, G3/4 port (PT/G/NPT thread options), and your mounting accessory. This -A variant specifies the SUS420J2 stainless rod; omit -A for the default carbon steel rod. Because this SKU lacks the -S magnet, it cannot accept position sensors; if sensing is needed, order the SAI160AX35S and use current AirTAC switches. Sizing both ways: the 160 mm bore yields 10053 N push and 9425 N pull at 0.5 MPa (max 2050 kgf at 1.0 MPa). If lower force is acceptable, a 125 mm bore provides 6136 N push. For load holding on air loss, a plain cylinder drifts—use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX35
- ✓ 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 SI160AX35 FAQ
Yes, the AirTAC SI160AX35 is discontinued. The direct replacement is the SAI160AX35. It shares the same ISO 15552 mounting interface, 160 mm bore, 35 mm stroke, force, G3/4 port, and SUS420J2 stainless rod, fitting existing fixtures perfectly.
The 160 mm bore uses a G3/4 port. Force output is 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 theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
