This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX950, 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 SI160AX950
The AirTAC Airtac SI160 Standard Cylinder SI160AX950 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 950mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX950, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX950
The AirTAC SI160AX950 is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 950mm stroke. Delivering 10053N push force at 0.5MPa, it features a 40mm SUS420J2 stainless rod, M36x2 thread, and G3/4 port. The direct replacement is the SAI160AX950, matching the interface, force, and mounting exactly.
This SKU lacks a magnet (-S), so it cannot accept position sensors like the legacy CS1-B/DS1-B. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. For load holding, note the cushion only decelerates; use SAIL or 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 SI160AX950 Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring sustained 10053N thrust at 0.5MPa with a robust 40mm stainless rod.
Pallet Diversion
Actuates heavy-duty pallet stops and diverters over the 950mm travel, relying on external guides to manage side loads.
Replacing the Airtac SI160 Standard Cylinder SI160AX950 with the SAI160AX950
To replace the SI160AX950, order the SAI160AX950. Confirm the ISO 15552 mounting interface, 950mm stroke, G3/4 port, and accessory type. This non-magnetic SKU cannot take switches; if sensing is needed, specify an SAI160X950S. The SUS420J2 rod (-A) resists corrosion versus standard carbon steel. At 0.5MPa it yields 10053N push and 9425N pull; sizing down to bore 125 gives 6136N. The 950mm stroke demands external guides to prevent rod-bending under side loads. For dead-load holding, select SAIL or BSAI lock variants, as standard cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX950
- ✓ 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 SI160AX950 FAQ
Yes, the SI160AX950 is discontinued. The direct replacement is the SAI160AX950. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 950mm stroke, force, G3/4 port, and mounting fixtures.
It features a G3/4 air port. Force ratings are: 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max of 2050 kgf at 1.0MPa. Speed is 30-500 mm/s.
