This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X900, 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 SI160X900
The AirTAC SI160 Standard Cylinder SI160X900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X900
The AirTAC SI160X900 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 900 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a 40 mm carbon steel rod, M36x2 thread, and a G3/4 air port. AirTAC replaced this legacy unit with the SAI160X900, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for lower start-up pressure and extended life. For load-holding, note that a plain cylinder drifts on air loss—the cushion only decelerates—so consider the SAIL lock or BSAI clamp-lock variants. This non-magnet SKU cannot accept a sensor.

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 SI160X900 Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring substantial thrust, utilizing the 14074 N push force at 0.7 MPa to manipulate heavy steel components.
Palletized Load Transfer
Shifts bulk palletized goods along extended 900 mm transitions, relying on external guides to prevent rod bending during high-mass horizontal indexing.
Replacing the Airtac SI160 Standard Cylinder SI160X900 with the SAI160X900
To replace the SI160X900, order the SAI160X900 direct equivalent, verifying your ISO 15552 mounting accessory (LB, FA, or TC), G3/4 port, and 900 mm stroke. This SKU lacks a magnet (-S), so it cannot support position sensing; if required, switch to an SAI-S model and use current AirTAC switches instead of the legacy CS1-B/DS1-B. For sizing alternatives, the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore provides 15708 N. Because the 900 mm stroke invites rod bending, ensure external guides absorb side loads. Remember that standard cylinders do not hold loads without live air; for fail-safe holding, specify the SAIL or BSAI lock variant, or add an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X900
- ✓ 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 SI160X900 FAQ
Yes, the SI160X900 is discontinued. The direct replacement is the AirTAC SAI160X900. It shares the identical ISO 15552 mounting interface, 160 mm bore, 900 mm stroke, output force, G3/4 port, and accessories, fitting directly into existing fixtures.
This double-acting cylinder has a 160 mm bore, 40 mm rod, M36x2 thread, G3/4 port, and operates at 30-500 mm/s. Force ratings are: push 10053 N and pull 9425 N at 0.5 MPa, push 14074 N at 0.7 MPa, push 18095 N at 0.9 MPa, with a theoretical maximum of 2050 kgf at 1.0 MPa.
