This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX700, 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 SI160AX700
The AirTAC SI160 Standard Cylinder SI160AX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX700
The AirTAC SI160AX700 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 700 mm stroke. It delivers 10053 N push and 9425 N pull at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160AX700, matching the interface, force, and mounting. This SKU uses an SUS420J2 stainless piston rod (-A) for corrosion resistance, but lacks a magnet (-S) and cannot accept a position switch.
The SAI160AX700 upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. For load holding, note that the air cushion only decelerates; use an external rod lock or SAIL/BSAI variant.

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 SI160AX700 Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring up to 14074 N thrust at 0.7 MPa, utilizing the robust 40 mm SUS420J2 stainless rod.
Automated Material Lifts
Hoists 512 kg payloads vertically over 700 mm cycles, relying on external guides to prevent rod bending during transit.
Large Assembly Actuation
Shifts heavy industrial subassemblies along 700 mm strokes, where the 50 mm adjustable cushions absorb high kinetic energy at end-stops.
Replacing the Airtac SI160 Standard Cylinder SI160AX700 with the SAI160AX700
To replace the SI160AX700, order the SAI160AX700. Confirm the ISO 15552 mounting interface, 160 mm bore, 700 mm stroke, G3/4 port, and M36x2 rod thread. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify an SAI with the magnet. The 700 mm stroke demands external guide rails to prevent rod bending under side loads. Sizing down, a 125 mm bore yields 6136 N push at 0.5 MPa; sizing up, a 200 mm bore provides 15708 N. For suspended loads that must not drift on air loss, select the SAIL or BSAI lock variant, as standard cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX700
- ✓ 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 SI160AX700 FAQ
Yes, the SI160AX700 is discontinued. The direct replacement is the SAI160AX700. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 700 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder uses a G3/4 port. It generates 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 maximum force of 2050 kgf at 1.0 MPa.
